That is, in a predetermined radius larger than the outer diameter of the mesoporous, the resin having the viscosity is dropped into the coating (the ring is just called the coating. Then, it is preferably followed by the spin coating. As the resin material) It is preferable to use an ultraviolet curable resin. The ultraviolet curable resin has high transparency and a short curing time, and is preferable in terms of production. Examples of the ultraviolet curable resin include a radical ultraviolet curable resin and a cationic ultraviolet curable resin.

The film which is cured by UV irradiation of the material line is the transfer layer 6. In order to make the transfer layer 6 have a light transmittance of laser light incident on the recording and reproducing functional layer 2, it is preferable to use a material which ensures sufficient transparency to the above-mentioned laser light. Here, in the present embodiment, "translucent (or transparent)" means that the laser light having the recording/reproducing functional layer 2 has sufficient penetration.

The pressure of the stamper 4 is _ above ^ = \ for the wavelength 400 (four), 100%. 1 0 / 〇 or more. The ideal upper limit of the tooth permeability is the stamper 4 In order to stipulate various materials from the resin tape, for example, 'available as a resin to be used, a carbonated resin can be directly used as a polyacrylic resin which is usually used as a substrate of a disc. In addition, in order to ensure that the stamper 4 and the usable (four) smoke are used It is a material of resin or polystyrene tree, which reduces the surface energy of the stamper 4. As described above, the shape is as follows: the mold is used for the mold 4, and the practical use is like amorphous two-two-dilute smoke. Resin (for example, ze〇nex (registered trademark) and • (° main volume trademark) (both manufactured by Nippon Co., Ltd.) 〇 Amorphous cyclic polyolefin has good peelability and is industrially excellent. Material: However, amorphous cyclic polyolefin is a special material, so The price, because the cost of the mold 4 will increase, and the resin mold 4 is not recyclable, so in fact, the cost of the stamper 4 in the optical recording medium as a whole is burdened by moxibustion. A resin which is as inexpensive as possible is used. Generally, a polycarbonate resin or an acrylic resin is used in terms of cost, and in terms of peelability, a polyolefin resin or polystyrene 312 χ ρ / invention is preferably used. Instruction Manual (Supplement)/96-06/96111269 27 200814050 Resin. In the present invention, when the transfer layer 6 is obtained, the ultraviolet curable dendritic film 5 is first semi-hardened. Thereafter, the ultraviolet uv is irradiated to ultraviolet rays. The curable resin film 5 is cured to obtain the transfer layer 6. According to the study of the present inventors, as described above, the transfer layer 6 can be improved by subjecting the ultraviolet curable resin film 5 to a semi-hardened state once. The peeling property of the stamper 4. The reason for this is not clear, but it is presumed that it may be caused by the following phenomenon.

In the case where the pressure is applied to the ultraviolet curable resin film 5, a chemical bond is generated between the stamper 4 and the ultraviolet curable resin film 5 to produce a crosslinked portion. Then, it is considered that the result may cause deterioration in peelability of the transparent pressure-drawing and hardening resin. In particular, when the material of the polar weight 4 is used, the chemical bond is more likely to occur at the interface between the stamper 4 and the ultraviolet curable resin film. In this case, it is considered to be subjected to intense irradiation of ultraviolet rays uv. In the environment of oxygen concentration, ultraviolet uv or the like is subjected to rapid hardening: the operation month is made to cure the ultraviolet curable resin film slowly (semi-hardening) @; The reaction of the tree Lai.

As described above, in the present invention, in the present invention, it is easy to ensure the releasability of the stamper 4 and the transfer layer 6 by semi-curing the ultraviolet curable resin, and the degree of freedom of the material used in the stamper 4 is exhibited. When it is enlarged, as described above, in terms of reducing the surface energy of the stamper 4, the polyolefin can be preferably used as the material of the stamper 4, but in the present invention, the above-mentioned highly functional resin can be used.

Further, the material of the stamper 4 may be used singly or in combination of two or more kinds depending on the combination and the ratio. & 壬 • Although not shown in Fig. 1(b), the stamper 4 is generally formed in a disk shape having a center hole formed in the center portion. ^ Furthermore, in the case of producing the stamper 4, the manufacturing method is arbitrary. For example, in the case where the stamper 4 is a resin stamper, a metal stamper (for example, a nickel stamper) having a (negative) concave-convex pattern opposite to that of the stamper* can be used. The stamper 4 is produced by injection molding or the like. Further, the thickness of the bunker 4 used in the present embodiment is generally desirably 〇3 mm or more in terms of shape stability and ease of handling. However, the yield is usually less than 5 mm. If the thickness of the stamper 4 is within this range, then it is easy to ensure sufficient light transmission. UXP/Invention Manual (Supplement)/96-06/96111269 29 200814050 Therefore, even if the ultraviolet uv is irradiated through the stamper 4 as described below, the ultraviolet curable resin or the like can be effectively cured, and the productivity can be easily improved. [2. Ultraviolet curable resin film 5] The ultraviolet curable resin film 5 is usually formed by the following method. In other words, the ultraviolet curable resin film 5 can be applied to the stamper 4 with a concave-convex shape for transfer by an additive (for example, an additive such as a photopolymerization initiator or a sensitizer) or a solvent. Formed in the face. The coating method is not particularly limited, and a spin coating method is usually used for the purpose of forming a uniform film thickness and being suitable for industrial production. In the case of using the spin coating method, the viscosity of the composition of the ultraviolet curable resin is usually 50 MPa·s or more and 35 Å Mpa· or less. By setting f within the viscosity range, the thickness of the transfer layer 6 can be easily controlled within the range of θ: within the range of X, and the right is set within the above-mentioned viscosity range.

And 35 and 丄 „ ^ A is called the eight r Tian culture specific and Lu, easy to make a thin transfer _, 6 (for example, 5 / πη or so), on the other hand is also easy to make a thick film thickness of the person 1(b), although not shown in the figure, in the case where the stamper is disc-shaped and the center shape=two, it is preferable to form the ultraviolet curable tree by the following method. The towel is coated with a UV resin dispersion into a (disPence) ring shape, and k is preferably used for spin coating. The second ultraviolet: ultraviolet curable tree used in the line hardening chest 5 The heat transfer is particularly limited. In terms of improving the transferability of the mold 4 and the recording characteristics of the upper recording and reproducing functional layer (described below) provided on the transfer layer 312XP/MiS__/_/96111269 3〇200814050 6 Preferably, the transfer layer 6 obtained by hardening is relatively strong in ultraviolet curing, and specifically, it is preferably an ultraviolet curable resin. The underarm=elasticity ratio is 300 MPa or more. The reason is that the resin having a high modulus of elasticity is rigid. Further, the elastic modulus refers to the usual dynamic viscoelasticity. The dynamic elastic modulus measured by the measuring machine. The higher the elastic 10 ratio of the ultraviolet curable resin used in the printing layer 6 is. 150. The elastic modulus of the underarm is preferably 3 (10) Mpa or more.佺33〇]^〇^ or more, and then better 35〇]^1^ or more, and even better 5〇〇]^1^ or more, and more preferably 75〇MPa or more, especially better than 95〇, the best 1000 MPa The above-mentioned gastric elastic modulus is a dynamic elastic modulus measured by a usual dynamic viscoelasticity measuring machine as described above, wherein, in terms of productivity, the elastic modulus of the ultraviolet curable resin at 15 (rc) Usually, it is 25 (8) or less. • In addition, when the modulus of elasticity at 150 ° C is 300 MPa or more, there is a tendency that the glass transition temperature of the resin becomes higher. Specifically, the bomb under i5〇t The glass transition temperature of the resin having a rate of 300 MPa or more is usually 140 C or more. On the other hand, the upper limit of the glass transition temperature is usually 200 〇C, and the shrinkage ratio of the ultraviolet curable resin used in the transfer layer 6 is suppressed. In terms of disc warpage, it is preferable that the shrinkage rate is small. In the ultraviolet curable resin having an elastic modulus, the shrinkage ratio tends to be relatively large. Further, if the shrinkage ratio is increased, the following advantages are easily exhibited. Shrinkage rate 312XP/invention specification (supplement)/96-06/96111269 31 200814050 is usually 6% or more, preferably 9Q/〇 or more, more preferably 95% or more, and more preferably ι〇% or more. The shrinkage ratio is preferably 20°/. or less. Here, the shrinkage ratio means The shrinkage ratio measured by the specific gravity method. The shrinkage ratio can also be measured in accordance with K71126.1, etc. The transfer layer 6 is formed by using an ultraviolet curable resin having a shrinkage ratio of 6% or more. When the stamper 4 is formed on the transfer layer 6, it is preferable to improve the peelability of the self-pressing die 4 when it is formed into a groove for recording tracks. The reason why the peelability of the stamper 4 is good is considered to be, for example, that the resin which has entered the groove of the stamper 4 shrinks during hardening, resulting in slight deformation or gap. As described above, in order to ensure the releasability with the stamper 4, it is preferred that the resin used in the transfer layer 6 has a predetermined shrinkage ratio or more. On the other hand, as a result of forming the transfer layer 6 from a resin having a large shrinkage ratio, shrinkage at the time of film formation of the transfer layer 6 tends to become large. It means that the optical recording medium as a whole becomes easiest. In view of this, the material of the lower intermediate layer 3 can be appropriately controlled to alleviate the warpage of the entire optical recording medium.

The rate of hardening shrinkage is a ratio of density change upon hardening of the density before hardening. Therefore, in order to reduce the shrinkage ratio, the density and cross-linking at the time of hardening can be reduced. Specifically, when an ultraviolet curable resin is formed by using an acrylic monomer, an acrylic oligomer and an acrylic monomer having a large molecular weight per propylene group and a small amount of propylene groups in the molecule can be combined. The content ratio of the acrylic acid-based polymer and the acrylic monomer can be appropriately controlled for the purpose of obtaining a desired elastic modulus. As a specific example of the acrylic oligomer, the same as (4) of the above-mentioned "method of resin having a small modulus of elasticity (for example, 301)" can be used. As a specific example of the acrylic monomer, the above-mentioned "method of obtaining a resin having a small modulus at room temperature (for example, 30T:)" can be used. [3. Semi-hardening of the ultraviolet curable resin film 5] As shown in Fig. 1 (b) (b-1), the ultraviolet ray curable tree 5 provided on the surface of the stamper 4 is irradiated with ultraviolet rays UV to harden the ultraviolet rays. Resin film 312XP / invention manual (supplement) / 96-06/96111269 38 200814050 5 semi-hardening. The method for curing the ultraviolet curable resin film 5 is as follows: /, the body U) The amount of ultraviolet irradiation is reduced. (b) Irradiation of ultraviolet UV in the presence of oxygen. • (c) Use (a) and (b) in combination. - The methods (a) to (c) of 10 are used as appropriate depending on the nature of the type of ultraviolet curable resin used. Fig. 1(b)(b-1) is an example of the above (c). In other words, the amount of ultraviolet irradiation is reduced in an atmospheric environment, and the ultraviolet curable resin film is made into a film. The following describes each method in detail. In the case of reducing the amount of ultraviolet radiation, either or both of the case of reducing the amount of light itself and the case of reducing the irradiation time can be considered. The amount of light of the external light UV is usually 50 mW/cm2 or less, preferably 40 mW/cm2 or less, more preferably 30 mW/cm2 or less. On the other hand, in order to more reliably perform the semi-curing of the ultraviolet curable resin film 5, the amount of ultraviolet light UV is usually lmW/cm2 or more, preferably 5 mW/cm2 or more, more preferably 7 mW/cm2 or more. When it is within the above numerical range, the peeling limit is increased and the industrial production is easy. In order to keep the curing of the ultraviolet curable resin film 5 at an appropriate stage, the irradiation time of the ultraviolet ray UV is usually 1 sec or less, preferably 5 sec or less, more preferably 3 seconds or less. On the other hand, in the case of semi-hardening, ultraviolet UV irradiation 312 χΡ / invention manual (supplement) / 96-06/96111269 39 200814050 time, usually 0.1 second or more, above 0, preferably 0.5 second or more, more preferably 1 If the second is within the above numerical range, the workable 4$ detachable limit can be easily increased, and the thickness can be increased. In the environment of reducing oxygen (for example, nitrogen environment), #,?, shooting the external UV of the rabbit, in 7 soil and h condition slaves to shorten the irradiation time. In this case, the irradiation time is usually (U seconds or more, =] in this b-direction, the irradiation time is preferably 3 seconds or less. In addition, the soil is more than the above. The ultraviolet curable resin is mostly difficult to exist in the presence of oxygen. The hardening property in the environment «. (4) In the case of a free-line curable resin, there is a tendency for oxygen in the air to react with free radicals to prevent hardening. Therefore, it is in the side @, Wei in the milk Irradiation of UV light under the 1st brother is also one of the effective methods for semi-hardening the ultraviolet curable resin film 5. The oxygen concentration in the case of ultraviolet 4tuv irradiation in the presence of oxygen is usually expressed as 〇1 or more in the height ratio. Preferably, it is 2 or more, more preferably 0.25 (about the oxygen concentration in the atmosphere) or more. If it is within this range, the polymerization inhibition by oxygen can be favorably controlled. On the other hand, the upper limit of the oxygen concentration is all of the atmosphere. In the case of the ultraviolet curable resin film 5 side, the ultraviolet ray UV is irradiated to the ultraviolet curable resin film 5 side, but it is of course possible to irradiate the ultraviolet uv from the side of the stamper 4, however, in the case of (b) (b). In the case of irradiating ultraviolet uv from the side of the stamper 4, The best system is to reduce the defects that hinder the ultraviolet irradiation in the stamper 4. [4. Hardening by ultraviolet irradiation in an environment where the oxygen concentration is reduced] In the present embodiment, as shown in Fig. 1 (b) (b-2) In the case where the ultraviolet curable resin film 5 is semi-hardened, the ultraviolet curable resin film 5 is further irradiated with ultraviolet rays 3 nXP/invention specification (supplement)/96-06/96111269 40 200814050 UV in an environment where the oxygen concentration is reduced. In the figure, the transfer layer 6 is obtained as an example of an environment in which the oxygen concentration is reduced, and the ultraviolet curable resin film 5 is further cured by irradiation with ultraviolet rays UV in a nitrogen atmosphere to obtain a transfer layer 6. The hardening of this step + is carried out until the surface of the ultraviolet curable resin film 5 (the surface of the ultraviolet irradiation side in Fig. 1(b) (b-2) is not sticky (adhesiveness). Further, the so-called tack function Specifically, the ultraviolet curable resin film 5 has a surface property in which the surface is not sticky with a finger. In this step, the ultraviolet curable resin film 5 is cured to form a transfer layer 6' Also take advantage of the following advantages. @ When the intermediate layer 3 is transferred to the lower layer, the surface of the transfer layer 6 becomes in a non-adhesive state, so that it becomes ==== in the transfer layer 6. As a result, it is not necessary to suppress the bubble two: The purpose is to make the interlayer 3 and the transfer layer 6 adhere to each other. The second intermediate layer 3 is easily formed in the atmosphere. The adhesion of the layers is in the nitrogen environment.

Alternatively, the peeling property of the transfer layer 6 and the stamper 4 may be impaired, and the transfer layer 6 may be easily hardened. In addition, in order to obtain the transfer layer 6 having a predetermined surface, the amount of light as ultraviolet UV 'is usually 30. mW/cm2 or more, preferably 5 〇mw/cm2 or more, more preferably 70 mww or more. If it is within the above numerical range, the surface hardening of the ultraviolet curable resin film 5 can be sufficiently performed, and transfer having a predetermined surface can be easily formed. Layer 6. The irradiation time of the ultraviolet ray UV can be appropriately controlled for the purpose of obtaining the transfer layer 6 having the surface of (4). Specifically, the irradiation time is usually 2 sec or less, preferably 15 sec or less, more preferably 1 sec or less. Better than $ seconds, especially better than 3 seconds' Preferably, it is less than 2 seconds. 3 UXP/Invention Manual (Supplement)/96-06/96111269 200814050 In another aspect, in order to obtain the transfer layer 6 having a predetermined surface, the irradiation time of ultraviolet UV is usually 0.2 second or more, preferably 〇 5 seconds or more, more preferably 0 · 7 seconds or more. [5. Film thickness of the transfer layer] Through the above steps, the transfer layer 6 is formed on the stamper 4. The thickness of the transfer layer 6 ensures transfer The hardness of the uneven shape and the peeling property of the transfer layer 6 and the stamper 4 are usually larger than 〇Mm, preferably 1 μm or more, more preferably ♦ otherwise, the film thickness of the transfer layer 6 is usually 2 or less, preferably 15 or less, more preferably 10 μm or less, still more preferably 5 or less. When the film thickness of the transfer layer 6 is within the above range, the hardness of the uneven shape of the transfer can be easily ensured, and The peeling property of the transfer layer 6 and the stamper 4 is easy to control the advantage of the embossing of the disc. When the film thickness of the transfer layer 6 is set to 1 〇 or less, the following advantages are easily exhibited. An operation of irradiating ultraviolet ray UV or the like by stretching a violet-external curable resin by spin coating even if omitted It is easy to make the film thickness distribution of the transfer layer 6 a good advantage. Second, since the film thickness of the transfer layer 6 is thinned, it is also advantageous in that the semi-hardened state of the ultraviolet curable resin film 5 is easily obtained. A case where a strong ultraviolet curable resin or an ultraviolet curable resin having a large shrinkage ratio is used in the transfer layer 6 in consideration of transferability or releasability, and in this case, the film of the transfer layer 6 can be thinned. When it is thick, it is easy to reduce the warpage of the entire optical recording medium.

Phase: Fig. Me—“So the transfer layer 6 and the lower intermediate layer 3 are transferred and laminated laminating molds _ placed under the lower intermediate layer 3, the intermediate layer 1 layer 6 and the recording and reproducing functional layer 2 In particular, the 'transfer laminated laminating mold 200 is carried out in any environment in the atmosphere or in a vacuum. Among them, only 8% of the application is carried out, preferably in a decompression environment. In other words, it is preferable to carry out a pressure-reduced environment in a reduced-pressure environment, and specifically, it is a vacuum-like separation. The reason why the reduction is performed in a reduced-pressure environment is as follows. That is, 11 Pa The respective surfaces of the lower intermediate layer 3 are not completely flat and have fine irregularities. Therefore, if the interface between the atmosphere and the intermediate layer 3 may enter, the transfer layer 6 and the lower layer are present in the intermediate sound 7 Such air enters 'will become the bubble door S ..., and, in terms of optical properties, it is better to reduce the above, and to prevent the entry of the above air (in other words, the bubble) than to reduce the wish environment _ carry : : : :: The specific willingness of the decompression environment can be listed as usually below.

For the following, as shown in the second figure rc) (c-2), the adhesion of the lower intermediate layer 3 to the transfer layer 6 can be achieved by the following method. For example, the adhesive is applied to the surface of the lower surface of the lower surface or the surface of the transfer layer 6, or the surface of the interlayer layer 3 of the 馘 ⁄ 丨 丨 丨 丨 四 四 四 四 四 四 四 四 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 Also 'for example, in the lower middle layer = UV-irradiated UV* adhesive under the intermediate layer 3 and the transfer: industrially, the lower intermediate layer 3 and the transfer layer 6 are all made of hard uv, in the middle, and the transfer layer is placed. After the mold is used, the method of irradiating the intermediate layer 3 and the transfer layer 6 by ultraviolet rays is irradiated. Further, in the case of using the method, the intermediate layer is preferably in an unhardened or semi-hardened state. Because the sex is programmed in the lower middle layer 3 and the transfer layer is sticky i ' === raw (adhesive feeling when touched with a finger), so it can be made sticky by making the lower side 5 曰 a face Further, it is easy to carry out the connection = the direction of the ultraviolet irradiation is not particularly limited, and the preferred mold 4 has a light transmissive property against the ultraviolet ray ν on the side of the stamper 4 (4) peeling pressure from the squeegee layer 6 After the step 3 between the layer 4 and the transfer layer 6, the stamper is peeled off from the transfer layer 6. The peeling method is also not particularly limited. Usually, the knife edge is inserted from the outer diameter side of the second plate to the stamper 4 and Between the printing layers 6, the stamper 4 is peeled off from the transfer layer 6 (not shown in Fig. 2 (4)). Further, in the case where the optical recording medium is in the form of a disk, the following side 312XP/ Inventive specification (supplement)/96-06/96111269 45 200814050: In::=Adsorption inner circumference' is cut into the inner circumference of the optical recording medium; /, the transfer layer 分离 and the stamper 4 are separated while blowing air. The burial d = two and the first recording medium 1 〇. The upper layer 7 having the lower intermediate layer 3 and the transfer layer 6 is formed. B. Second Manufacturing Method Next = Medium, the lower intermediate layer is formed in the bonding step. Except that the formation of the lower intermediate layer is different from that of the first manufacturing method described above, i is the same as the first manufacturing method, and the same is true. Therefore, the following is only for the different parts; =,, and the body is the same, in the second manufacturing method, In the middle of the second, the heart is made by the heart of the brother 1 and the recording medium is made into the lower intermediate layer', and the lower intermediate sound is formed when the bonding step is performed. Fig. 3 is a diagram for explaining the second side of the second image 』t, earth && /v, 曰. And the embodiment of the first manufacturing method is shown in the figure. Further, in W 3, the same symbols as those in Fig. 1 or Fig. 2 are denoted by the same reference numerals. Moreover, the composition is required to be hoisted at the center, and the media has been recorded as a disc, forming a middle hole, but the description of the center hole is omitted in FIG. | The outline of each figure is explained below. Fig. 3 (4) shows a state in which the curable resin 8 is applied to the recording. Further, it is shown that the transfer laminated laminate mold 200 is placed on the upper side in order to be placed on the curable tree. 3(b) shows a state in which a curable resin 8 〇 and a transfer layer are placed on the curable resin 80, and a transfer lamination mold is used to stretch the curable resin 8 。. ( Fig. 3(4) shows a state in which the curable resin 8〇 is extended to both end portions of the first transfer laminate lamination mold 200. T嫖版1〇〇 and 312XP/Invention Manual (Supplement)/96-〇6/96 i丨i 269 46 200814050 Figure 3(4) shows how the ultraviolet uv is irradiated to form the lower intermediate layer 3 layer 7. The joining step in the present embodiment between the τ and the following will be described with reference to Fig. 3 . First, as shown in Fig. 3 (a), a curable resin 8 is applied onto a recording medium 100 (recording re-flavor #台bμ^球冉生功层2). As the material of the curable resin 80, the same as the case where the curable resin is used in the intermediate layer 3 of the second manufacturing method in the second manufacturing method can be used. In the present embodiment, other types of curable resin such as a thermosetting resin may be used as the curable tree. Among them, considering the film thickness control of the lower intermediate layer 3, industrial production, etc., the lanthanum-curable resin 8 〇 is an ultraviolet ray, a μ μ + body, a body, and a spring-curable resin. The method of applying the curable resin 80 can also be carried out by a previously known method. Here, in the shape energy φ ^ of the present embodiment, the curable resin 8 主 can be directly applied to the recording/reproducing functional layer 2, and when it is missing, it is necessary to form another layer on the recording and reproducing functional layer 2, and then harden the coating. Resin resin 8 〇. In addition, in Fig. 3(a), although the shape is inferior, the shape is not shown, when the substrate 1 is in the shape of a disk, and the center t is formed into the mesopores, the formation of the Tude, s# soil interdiction layer 3 is hardened. The main distribution band of the resin 80 is preferably carried out in the following manner. That is, it is hardened and applied at a position larger than the outer diameter of the mesoporous body.

On the other hand, the transfer layer is composed of a stamper 4 and a transfer layer 6. On the surface of the stamper 4, the uneven shape of the uneven shape of the opening layer 7 is transferred. Then, the transfer layer 6 is formed on the surface of the uneven shape. The first Vi 00, the transfer laminated lamination mold 200, and the like are the same as those of the first manufacturing method, and thus the description thereof is omitted here. Correct:! As shown in Fig. 3(b), the transfer lamination mold m is placed on the curable resin 80 in a 200 + ± form of the curable resin 80 and the transfer layer 6, preferably as much as possible. The air or the surface that does not enter the bubble is 6# j, which is the first to make the recording and reproducing function layer 2 sound and the p/ surface is almost parallel to the opposite side. Then, the curable resin 8 was dispensed in the gap of each of the following: immediately, the curable resin 8〇 was adhered to the respective surfaces. ^ And think began to extend the hardening resin 8〇. In the present embodiment, the eucalyptus is laminated and the laminate is laminated: Extending the film of the curable tree film by means of the above, ten, and ^ ^ will easily extend the formation of hard pure (4) (9) to the desired range. Of course, the extension of the curable resin 80 can also be carried out by a spin coating method or the like. Further, according to j, as shown in Fig. 3 (4), the curable resin 80 is reached and the transfer laminated laminate mold 2 is reached. . After both ends, the high month & transfer and transfer laminate mold 200' removes the excess hardenable tree moon 80 to the outside. Thereby, it is easy to more precisely control the film thickness of the crucible formed by the hardenable tree = 312XP / invention specification (supplement) / 96-_61 „ „ „ s s s s s s s s s s s s s s s s s s s s s s s s s The resin 80 is shaped like a crucible, and as shown in Fig. 3 (d), the ultraviolet curable resin 80 is cured by ultraviolet rays from the side of the stamper 4, and the curable resin 80 (ultraviolet μ &&& curable resin) is cured. There is a state of the lower intermediate layer 3 between the printing layer 6 and the brother 1 § recording media 1 n rn ', 00 (5 recorded reproduction function layer 2), and the bonding embossing die 200 and the first Recording medium 100. One of the advantages of the second manufacturing method is that the bonding step can be performed in the atmosphere. Specifically, the various operations under the 夂 ρ ^ / hall shown in Fig. 3 (at least Figure 3 (a) to The operation of Fig. 3(c)) can be carried out in the atmosphere. The result is that the composition of the device can be simplified. The reason for the bonding step in the atmosphere is as follows. The transfer layer lamination mold _ is placed between the hard resin 8g and the hard curable resin 8G, and will exist between the hard 4 and the recording and reproducing functional layer 2 The air 'is discharged from the curable resin 80 to the outside of the i-th recording medium i · the laminate lamination mold 200. As a result, it becomes difficult for air to enter between the mold 4 and the curable resin 80 (and thus the lower intermediate layer 3). Thereby, the bubbles generated at the interface between the stamper 4 and the lower intermediate layer 3. As a result, the joining step may not be performed in a vacuum. As described above, the forming of the intermediate layer 7' performs the peeling step of the stamper 4. At this point, It can be the same as the second manufacturing method (refer to Fig. 2(d)). The description of the = step has been omitted, and the description is omitted here. The carving C. The subsequent steps In the present embodiment, as described above, the manufacturing has the surface unevenness.

Furthermore, for the figure and Figure 2 Figure 3 The common constituent elements are denoted by the same reference numerals. As shown in Fig. 4, on the formation of the grooved depressions ## 7), the transfer layer 6 of the upper layer is formed (the intermediate layer 8 is too much connected: The raw functional layer 8. The upper recording and reproducing functional layer Qin 2' is substantially the same as the recording and reproducing functional layer 2.

Preferably, the material is the same as that of the characteristic plate such as the warpage of the optical disk, and the bonding layer 9 is coated with the μ 1 () ^ ′ and the integrated layer 10 is integrated. At this time, the smectite resin used in the outer earth is usually 1000 mils.

According to the number used! Record the media; rumors, there are the following differences. At the first point, the surface of the present embodiment has a concave shape and b b , and the interlayer is formed on the substrate without intervening the recording regenerative work with the intermediate layer of the (4) printing layer. 312XP/Invention Manual (Repair)/96·06/96111269 51 200814050 =' It is not necessary to provide a concave-convex shape on the substrate in advance. Secondly, in the present embodiment, the recording and reproducing functional layer initially disposed on the substrate will become the upper recording and reproducing functional layer. As described above, in addition to the difference in the form of the first recording medium to be used, the method can be manufactured in the same manner as the above-described i-th recording medium having the i-layer recording and reproducing functional layer, and has a surface having a concave-convex shape and having a lower surface. An optical recording medium of an intermediate layer between the intermediate layer and the transfer layer. The necessary explanations have been explained, so the description is omitted here. In the case where a recording medium having a plurality of recording and reproducing functional layers is widely used, the present embodiment "is different from the above-described "recorded and reproduced functional layer". The embodiment of the "recorded media" for producing optical recording media is also different depending on the format of the first recording medium. Specifically, the difference is as follows: First, in the manufacture of the first recording medium (4), by: Forming a plurality of recording and reproducing functional layers to form a dielectric second (two) position/application form, and in the bonding step, 'in the lower middle layer when the transfer layer and the recording and reproducing functional layer are read from the substrate Bonding the transfer laminated lamination mold to the above-mentioned first recording medium. θ As described above, in addition to the form of the recording medium to be used, it is possible to have the first layer of the recording and reproducing functional layer described above!

Then 312XP / invention manual (supplement) / 96-06/96111269 52 200814050 usually The following method is used in the conventional embodiment. The recording medium (4) is used to form a recording and reproducing functional layer on the substrate. (8) The inter-center sound is formed on the recording and reproducing functional layer. (C) Formed on the intermediate layer. The second record 2 (4) is used in the second recording/reproducing functional layer (4) to reproduce the functional layer according to the required recording; the second step is to repeat the above-mentioned (c), (d) layered recording and reproducing function layer number recording and reproducing function. The number of layers in the layer is 10 layers = 1. However, in reality, the number of layers of the regenerative functional layer is usually more than 5 layers. In view of industrial production = preferably 3 layers or more, The number of layers of the optimum recording and reproducing function layer is 2, and the number of layers is 2, and the layer structure and material of the second recording and reproducing θ energy layer can be used. The recording and reproducing function # 2) The phase consists of the same layer of the regenerative function layer (Fig. 1, the figure). In addition, the middle layer after the middle layer of Chengdi 2 is also the material of the layer or Production order, structure of the stamper, by ::: The details of the order of the transfer and the like may be the same as those described above., ",, the hard work of the shoot - 4, the other two t = the == a plurality of implementations y Yafei is limited to the above-mentioned forms, Excessively within the dry circumference of the main body of the present invention, it can be appropriately changed and implemented. For example, the layer configuration of the optical recording medium is not limited to the configuration of 312XP/Invention Duck (Supplement)/96-06/96111269 53 200814050 of the above embodiment. In the range beyond the scope of this report, the addition of other layers, and the purpose of the manufacturing device, there may be different layers to integrate two or more layers. The shape::, also provides a kind of optical recording medium having a surface having a concavo-convex shape: an intermediate layer having a lower intermediate layer and a transfer layer. Specifically, in order to manufacture a transfer layer laminate mold, the following functions are added to the build-up. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The curable resin film is semi-hardened. Further, a second hardening means is added: the ultraviolet curable resin film is further cured by a ring of ultraviolet rays / ampere of <RTIgt; The specific operations of the first hardening means and the second hardening means are the same as those described in the manufacturing method of the above description, and the description thereof is omitted here. Further, the specific device configuration for realizing the first curing means and the second curing means can be suitably used to improve the conventionally known manufacturing apparatus. (Embodiment) Hereinafter, the present invention will be described in more detail based on examples. Furthermore, the present invention is not limited to the following embodiments without departing from the gist thereof. (Example 1) (First recording medium manufacturing step) A polycarbonate substrate having a thickness of j j mm having a groove depth of about 20 nm and a pitch of about 〇·32 μηι was transferred. Forming a rewritable recording and reproducing functional layer on the surface of the substrate formed by the sputtering method 312XP/invention specification (supplement)/96·06/96111269 54 200814050 by sputtering (example 1 of the rewritable medium) , film surface incidence constitutes). The first recording medium is manufactured in this manner. (Transfer Laminated Molding Process Manufacturing Step) A polycarbonate transparent to a groove having a groove depth of about 20 nm and a pitch of about 〇32 Mm is transferred by injection molding, and the outer diameter i2 is transparent. Pressing a die to apply a radical _ 1 external curable resin (radical polymerization type ultraviolet curable resin) A (acrylic resin) to the surface on which the stamper is formed by spin coating The viscosity is about 3〇〇Mpa·s). Then, the above-mentioned radical-based ultraviolet curable resin A is formed into a film shape having a thickness of about 4, and the 彳τ check speed is rotated. As described above, an ultraviolet curable resin film is formed on the stamper. After that, in the atmosphere, the entire surface of the ultraviolet curable resin film was irradiated with φν light having a substantially average intensity distribution of 22 mW/cm 2 (light source, TOSCURE 751 by Hari_Toshiba) for 3 seconds. After the irradiation, the surface of the ultraviolet curable resin film is touched to be in an adhesive state. Then, the uv light 1 which is emitted from a light source having a substantially average intensity distribution of 8 〇 mW/cm is applied to the entire surface of the ultraviolet curable resin film. The transfer layer was thus obtained. The surface state of the transfer layer is a state in which it is difficult to scratch even if it is rubbed with a sharp metal. The transfer laminated laminate was produced as described above. (Joining step) On the surface of the recording and reproducing functional layer of the first recording medium, a radical-based ultraviolet curable resin is placed at a position of a radius of about 35 mm (radical poly 312XP/invention specification (supplement)/96·〇 6/96111269 200814050 Combined UV curable resin) B (Li-acrylic acid A/fn, human w-system sealant, viscosity about 500 MPa · s) is coated in a one-week ring shape. Then, the surface of the ultraviolet ray-curable tree 曰B is opposite to the transfer layer, t, and the type of the free radical ultraviolet ray-curable tree B is placed on the transfer layer > f曰岭盾茔杈.

From the ^ ^, after eight, the entire surface of the self-compressed side is irradiated from the same source of light 80 mW / cm 2 and right husband $ 々 仏 仏 Α ^ ^ ^ There are roughly a thousand average intensity distribution of UV light 6 The second button is used to harden the lower layer. (Peeling step) Thereafter, when the transparent stamper is peeled off from the transfer layer, peeling can be performed in a good state in which the entire surface is not uneven at the interface of the transparent stamper transfer layer. (Formation of the upper recording and reproducing functional layer) Further, a rewritable upper recording and reproducing functional layer is formed on the transfer layer by sputtering (the rewritable medium is exemplified as a film surface incident), and further spin-coated with a resin The law forms a thickness of 75 eves, and the Kun Cui 丨 is shipped with a tree light disc. Further, a double-transfer type blue was produced for the coating layer of 75 Å. (Evaluation) No. The transfer property of the transfer to the transfer layer in the double-transfer type blue-light-disc manufactured by the above-described production method was evaluated. As a result, it was found that the groove signal can be selected, and the entire surface can be transferred well. X (also, Comparative Example 1) In the "transfer layering lamination mold manufacturing step" of the first embodiment, except for only the 312XP/invention specification (supplement)/96-06/96111269 56 200814050 SI: under the initial atmosphere In the same manner as in the first embodiment, 22 mW/cm, UV irradiation (operation without the operation of the double-butting +=), and the case where the shape of the upper recording and reproducing functional layer is not performed is attempted to produce light in the same manner as in the first embodiment, so that it is difficult to peel off. In fact, if the peeling is forcibly carried out = the township monthly stamper, and the mark on the recording and reproducing functional layer = peeling. Then the entire surface of the film of the recording layer formed by the surface is broken (Example 2) except that it will be implemented. In the "transfer layered multilayer mold manufacturing step" of Example 1, the uv light irradiation of the rib mw/cm2 is set to 1 second, and the step material after the "second = regeneration functional layer formation" is not performed, and is implemented. Example 1 The same method was used to make an optical recording medium. As a result, in the peeling step, only the film of the partially deposited recording layer was peeled off, and the peeling of the transfer layer and the transparent stamper was basically performed well. (Example 3: Experiment of changing the resin material of the transfer layer and the lower intermediate layer (first recording medium manufacturing step), x Preparation for transfer of a groove J having a groove depth of about 2 〇 nm and a pitch of about 0.32 jUm a substrate made of polycarbonate of i mm.

A transparent stamper made of polycarbonate having a diameter of 120 mm. The surface of the stamper formed on the grooved surface is coated with a radical type M2XP/invention specification (Supplement 57 200814050 UV curable resin (radical polymerization type) The ultraviolet curable resin c (acrylic resin, viscosity: about 300 MPa · s). Then, the above-mentioned radical 糸I and the external curable resin C are formed into a film having a thickness of about 4 μm, and then the high-speed ejection rotation is stopped. As described above, an ultraviolet curable resin film is formed on the stamper. Then, in the atmosphere, the entire surface of the ultraviolet curable resin film was irradiated with υν light (light source: TOSCURE 751 manufactured by Harison Toshiba) having a substantially uniform intensity distribution of 22 mW/cm 2 for 3 seconds. Touching the surface of the ultraviolet curable resin film to be in a state of adhesion. Then, in the nitrogen atmosphere, the entire surface of the ultraviolet curable resin film is irradiated with a light source having a substantially uniform intensity distribution of 8 〇mW/cm 2 . Light is passed for 1 second. The transfer layer is obtained as described above. The surface state of the transfer layer is a state in which it is difficult to scratch even if rubbed with a sharp metal. The transfer laminated lamination mold is manufactured as described above (joining step) On the surface of the recording and reproducing functional layer of the recording medium, a radical-based ultraviolet curable resin (radical polymerization type ultraviolet curable resin) D (acrylic resin, adhesive MPa) is placed at a radius of about 35 mm. S) is applied to the ring-shaped ring. Then, the ruthenium radical-based ultraviolet curable resin D is placed on the surface opposite to the transfer layer, and the above-mentioned radical-based ultraviolet curable resin D is placed thereon. The layer of the printed layer is multi-layered. After the radical ultraviolet curable resin D is extended to the end of the recording medium and the transfer layer mold, the first recording medium is rotated by 5_, and the excess radical is removed. The ultraviolet curable resin D is discharged to the first recording medium and the 312XP/invention manual (supplement)/96·〇6/961丨丨汹58 200814050 the outer layer of the printed layer _. The surface is irradiated with an intensity distribution of 8 〇mW/cm 2 from the same light source and having a substantially uniform hook; the light is rubbed for 6 seconds to harden the lower intermediate layer. (Peeling step) Thereafter, if the transparent stamper is peeled off from the transfer layer Then, the interface between the transparent stamper and the transfer layer can be peeled off in a good state without unevenness on the entire surface. (Example 4: Experiment of semi-hardening under nitrogen) Xin (first recording medium manufacturing step) Preparation of a polycarbonate having a groove depth of about 2 〇 nm and a pitch of about 32.32 μηι The base is reversed. A rewritable recording and reproducing functional layer (Example 1 of a rewritable medium, incident on a film surface) was formed on the surface of the substrate formed with a groove by the method (4). The ith recording medium is thus manufactured. (Transfer layer lamination mold manufacturing step) By injection molding, a polycarbonate transparent transparent press having a groove width of about 20 nm, a groove having a pitch of about 0 32 Mm, a thickness of 0.6 mm, and an outer diameter of 12 legs is manufactured. mold. A radical-based ultraviolet curable resin (radical polymerization type ultraviolet curable resin) A (acrylic resin, viscosity of about 3 〇〇Mpa·s) is applied onto the surface of the stamper having a groove shape by spin coating. . Then, the above-mentioned radical ultraviolet curable resin A was formed into a film shape having a thickness of about 4, and then rotated at the same speed. As described above, an ultraviolet curable resin film is formed on the stamper. Then, UV light having a substantially uniform intensity distribution (light source, TOSCURE 751 manufactured by Hanson Toshiba) of 10 mW/cm was irradiated to the entire surface of the ultraviolet curable resin film in the air atmosphere for 0.2 seconds. Photograph 312XP/Invention Manual (Supplement)/96-06/96111269 200814050 After the shot, touch the surface of the ultraviolet curable resin film to make it adhere. Then, in the nitrogen atmosphere, the entire surface of the ultraviolet curable resin film was irradiated with uv light of a light source having a substantially uniform intensity distribution of 80 mW/cm 2 for one second. The transfer layer was obtained as described above. The surface state of the transfer layer is a state in which it is difficult to scratch even if it is rubbed with a sharp metal. The transfer laminated laminate was produced as described above. (Joining step) On the surface of the recording/reproducing functional layer of the first recording medium, a radical-based ultraviolet curable resin (radical poly-σ垔糸 external curable resin acrylic resin, viscosity) at a position of a radius of about 35 mm About 1 〇〇〇r^s) is coated as a ring of weeks.

After the mold stick, the 80 mW/cm2 from the _= 冋 source has a substantially uniformity of 6 seconds, and the lower intermediate layer is hardened. X π UV light (peeling step) Thereafter, if the transparent stamper is peeled off from the transfer layer, the interface of the stamp is used to face the entire helmet; ^ β i , can be transparent stamped and transferred (Example 5) All are in good condition for separation. In addition to only Example 4, the transfer of the reed π 9 $ 'the initial illumination of the υ ν 312 ΧΡ / invention instructions (supplement) / 96-06/961 11269 60 200814050 irradiation time (for semi-hardened uv irradiation time) An optical recording medium was attempted in the same manner as in Example 4 except that 2 seconds was changed to seconds. In the peeling step, only the partially deposited recording film is peeled off, and the transfer layer and the transparent stamper are substantially peeled off. The method of forming the transfer layer in the λ yoke examples 4 and 5 has the advantage of not having to change from the atmospheric environment to the nitrogen atmosphere when the transfer layer is irradiated with 2-human UV light. However, in the transfer lamination mold manufacturing step, the difference between the irradiation intensity of the uv light used for the semi-hardening and the irradiation intensity of the UV light used for the further curing (second hardening) is large. . Therefore, if semi-hardening and subsequent hardening are to be carried out using the same UV irradiation device (υν source), there is a tendency that the type of the υν irradiation device (υν source) which can be used in the industry is limited. Further, the range of the ultraviolet irradiation intensity and the irradiation time in the case of the semi-hardening is narrowed, and the manufacturing limit of the optical recording medium tends to be small. In view of the above, it is considered that semi-hardening is preferably carried out in an environment in which oxygen is present. (Reference Example) In addition to the "transfer laminated laminate mold manufacturing step" of the first embodiment, the first step is to irradiate the ink of 200 claws/〇12 to 2 hours in the atmosphere for 2 seconds, and thereafter, it is not carried out in a nitrogen atmosphere. The optical recording medium was attempted in the same manner as in the Example except that the steps of the "second recording and reproducing functional layer t formation" were not performed. Here, in order to confirm the surface state of the ultraviolet curable resin film before the bonding step, the surface of the ultraviolet curable resin film that is touched by the finger is slightly adhered (semi-hardened state). That is, in this experiment, the transfer layer was not formed, but the ultraviolet curable resin film in a semi-hardened state was used. The bonding step was carried out in accordance with the specification (supplement)/96-06/96111269 61 200814050. The sound is “small” and the stripping step is carried out, and only a part of the machine is made into a record missing. “The transfer layer and the transparent layer are basically peeled off.”, and: In addition to the uv light of 1 〇〇mW/cm2, after the peeling step is carried out with the same member, the film of the recording layer of Chengcheng is peeled off as a whole. - From the results of the test, it is known that the film is semi-hardened. The peeling of the Hr I layer and the transparent stamper. However, in the method of the present experiment, the surface of the ultraviolet curable resin film is viscous, and the bonding step is performed. In the case where bubbles are introduced between the transfer layer and the lower intermediate layer, if the amount of irradiation of the uv light is lowered, the peeling of the uv light may be poor. Therefore, in order to ensure productivity, it is necessary to illuminate the clothes with UV light at a cost. Further, it is disadvantageous in that the semi-hardening is further hardened in an environment in which the oxygen concentration is reduced, which is effective in achieving cost reduction in industrial production and improving production stability or yield. _ (Industrial availability) ) Optical recording medium of the present invention The manufacturing method can be preferably applied to various optical recording media such as CD, DVD, BD, etc. Further, the present application is based on the patent application filed on March 31, 2006 (the patent application 2 (10) 6 -1〇〇145), the whole of which is hereby incorporated by reference.
