[Industrial Application Field] The present invention relates to an information processing device and an information recording method, and particularly to an information processing device and an information processing device using an optical recording element capable of highly reliable and high-density recording using a highly molecularly oriented organic thin film. This relates to an information recording method. [Prior Art] Recently, optical disks have been attracting attention as a central player in office automation (OA). The reason is that a single optical disk can store a large amount of documents,
This is because it can record (or memorize) documents, etc.
Therefore, if an information storage device using optical disks is introduced, it will be easier to organize documents and documents in the office.
This will bring about a major change in management. Furthermore, as recording elements for optical disks, elements made of organic materials, which have characteristics such as low cost, ease of manufacture, and high-density recording, are attracting attention. Among the conventional techniques using such organic recording materials,
In particular, a two-component optical recording element that utilizes a color reaction caused by contact between a color former and an auxiliary colorant has been reported (Nikkei Sangyo Shimbun, October 18, 1981). An example of a recording process by an information storage device using the conventional optical recording element will be explained based on the drawings.The optical recording element has a coloring agent layer 7 and an auxiliary coloring agent layer 5 as shown in FIG. 2a. are stacked on a substrate 1 separated by a light absorption layer 6. The coloring agent (leuco compound) and auxiliary colorant are colorless or light-colored when each exists alone. When recording on the optical recording element, a laser beam 8 is irradiated onto a desired position of the light absorption layer 6 as shown in FIG. It absorbs, melts, and tears, leaving small holes. As a result, as shown in FIG. 2c, the color forming agent and the auxiliary color agent, which were separated by the light absorbing layer 6, mix through the small holes and develop a color. Information is recorded or stored in the form of coloring points 9, and reading is performed by scanning the recording element with another light source and detecting changes in reflectance, transmittance, etc. due to the coloring points. [Problems to be Solved by the Invention] In the above information storage device, in order to achieve high recording density, the optical recording element has a light absorbing layer 6 that is as thin as possible, flat, and without unevenness in film thickness. desirable. However, in conventional optical recording elements,
Since the light absorption layer is coated on the substrate by, for example, a vacuum evaporation method or a spin coating method, the thickness may be reduced.
If an attempt is made to reduce the thickness to 200 to 500 Å or less, pinholes tend to occur frequently, and the two components, the color former and the auxiliary color, come into contact with each other at these pinholes and develop color, resulting in a lack of reliability. Furthermore, since the molecular distribution orientation within the film of each layer formed by the conventional coating method described above is random, light scattering occurs within the film with light irradiation, and when viewed microscopically, each light irradiation The degree of chemical reaction that occurs differs each time. moreover,
The above-mentioned coating method has drawbacks such as unevenness in film thickness and uneven recording quality when increasing the area of the substrate of the optical disk. Therefore, as an optical recording element, it is desirable that the molecular distribution and orientation within the film be uniform, that there are no pinholes, and that the film thickness is uneven, and that the film thickness be as thin as possible to achieve high recording density. Required for high reliability. The present invention was made in view of such demands,
An object of the present invention is to provide an information processing apparatus and an information recording method using an optical recording element capable of highly reliable and high density recording. Another object of the present invention is to provide an information processing apparatus and an information recording method using an optical recording element that is easy to manufacture and inexpensive. Still another object of the present invention is to provide an information processing apparatus and an information recording method using a large-area optical recording element. [Means for Solving the Problems] and [Operation] That is, the present invention provides a layer A containing a color-forming compound that is normally colorless or light-colored, and a layer B containing an auxochrome compound that develops a color when in contact with the color-forming compound. an optical recording element comprising a layer A, a light absorption layer, and at least one of the A layer, the B layer and the light absorption layer is a monomolecular film of a constituent material or a cumulative film thereof; This is an information processing apparatus characterized by having an information writing means for writing information and an information reading means for reading the information written on the optical recording element. Furthermore, the present invention irradiates the optical recording element with infrared rays according to the information to be recorded, melts or sublimates the light absorption layer, and brings the color-forming compound and the auxochrome compound into contact to develop color. An information recording method and an optical recording element characterized in that:
This information recording method is characterized by irradiating infrared rays according to the information to be recorded, and causing a color-forming compound and an auxochromic compound to react with each other to generate color due to the heat generated in the light-absorbing layer. . The present invention will be explained in detail below. FIG. 1 is a block diagram showing an example of an information processing apparatus according to the present invention. In FIG. 1, the information processing device of the present invention includes a layer A containing a normally colorless or light-colored color-forming compound, a layer B containing an auxochrome compound that develops a color when in contact with the color-forming compound, and a light-absorbing layer. An information writing device comprising an optical recording element having a layer, and at least one of the A layer, the B layer, and the light absorption layer is a monomolecular film of a constituent material, and is composed of a cumulative film thereof, a control circuit 27, and an optical pickup optical system. and an information reading means consisting of an output circuit 28 and an optical pickup optical system. Writing is performed as follows. Control circuit 27
controls the oscillation of the semiconductor laser 26. Therefore,
The input information is converted into an optical signal by the control circuit 27 and the semiconductor laser 26. The optical signal 29 passes through the optical pickup optical system shown in FIG. 5, forms an image on the recording layer of the synchronously rotating optical disk 18, and is recorded in color by the coloring mechanism described above. Reading is performed as follows. Low-power continuous wave light emitted from the semiconductor laser 26 is used as reading light. This is because, since the output is low, color recording is not performed during reading. Alternatively, other visible light sources may be used as the reading light source. The reading light beam forms an image on the substrate surface of the optical disk 18 and is reflected, but since the reflectance differs between the coloring point and the non-coloring point, this reflected light is passed through the optical pickup optical system to the light receiving surface of the photodiode 25. By applying the signal, it is converted into an electrical signal and read out for reproduction. In order to increase the contrast of the reproduced signal and improve the image quality, it is preferable to provide a metal reflective layer of aluminum or the like on the substrate of the optical recording element. The thickness of the metal reflective layer is preferably 1000 Å to 2000 Å. In addition, a dielectric mirror may be used as necessary. Furthermore, a protective layer may be provided on the surface of the outermost layer to protect the A layer, B layer, light absorption layer, etc. of the optical recording element. Suitable materials for such a protective layer include dielectrics such as SiO 2 , plastic resins, and other polymerizable LB films. The optical recording element used in the present invention is usually composed of a layer A containing a color-forming compound that is colorless or light-colored, a layer B containing an auxochrome compound that develops color when in contact with the color-forming compound, and a light absorption layer. Basically, it is required to use a combination of substances that develop color when brought into contact with and mixed with each other in the A layer and the B layer. Specific examples of the normally colorless to light-colored color-forming compound in layer A and the auxochrome compound that develops color when in contact with the color-forming compound in layer B, which have this relationship, are as follows: (a) Acidic substance (layer B) and the leuco form (dye precursor) of the dye that develops color when it comes into contact with the acidic substance (layer A) (b) The oxidizing agent (layer B) and the leuco form of the dye that develops color when it comes into contact with the oxidizing agent. Leuco body (layer A) (c) Reducing agent (layer B) and leuco body of a dye that develops color upon contact with the reducing agent (layer A) (d) Reducing agent (layer B) and stearic acid secondary Examples include oxidizing agents (layer A) that develop color when reduced, such as iron (e) oxidizing agents (layer B), and reducing agents (layer A) that develop color when oxidized, such as gallic acid. To give a more detailed example of the case (a) above, the acidic substance in layer B that reacts with the leuco form of the dye to develop color is an aromatic sulfonic acid compound such as benzenesulfonic acid, or an aromatic compound such as benzoic acid. Higher fatty acid carboxylic acids such as carginic acids, palmitic acid (C 15 H 31 COOH), stearic acid (C 17 H 35 COOH), arachidic acid (C 19 H 39 COOH),
pt-butylphenol, α-naphthol, β
- Naphthol, phenolphthalein, bisphenol A, 4-hydroxydiphenoxide, 4-
Examples include phenolic compounds such as hydroxyacetophenone. Next, examples of the leuco dyes in the A layer that react with the acidic substance include triphenylmethane, fluoran, phenothiazine, auramine, and spiropyran. The details of the compounds are shown in Table 1.

で示されるミトラーズヒドロール１部を[Table] Next, as the light-absorbing substance used to form the light-absorbing layer in the present invention, any light-absorbing dye that absorbs infrared rays may be used, such as a fusible light-absorbing material that absorbs infrared rays and melts. A dye, a sublimable light-absorbing dye that absorbs infrared rays and sublimes, a non-melting dye, a non-sublimable dye, etc. can be used. Examples of such light-absorbing dyes include metal phthalocyanines such as copper phthalocyanine and vanadium phthalocyanine, and xanthene dyes such as fluorescein. In the optical recording element used in the present invention, at least one of the A layer, B layer, and light absorption layer is composed of a monomolecular film of each constituent material or a cumulative film thereof.
It has three characteristics. Therefore, layer A,
When the B layer or the light-absorbing layer forms a monomolecular film or a cumulative film thereof, the above-mentioned color-forming compound, auxochrome compound, or light-absorbing substance has a hydrophilic group or a hydrophobic group at an appropriate site within the molecule. It is necessary to use a derivative into which one or both groups are introduced. Any commonly used hydrophobic group and hydrophilic group can be used, but
Particularly preferably, the hydrophobic group has 5 to 30 carbon atoms.
The long-chain alkyl group and hydrophilic group are preferably carboxyl groups and metal salts thereof (eg, cadmium salts). On the other hand, if the A layer, the B layer, or the light absorption layer does not form a monomolecular film or a cumulative film thereof, any film can be used as each layer as long as it is formed by a conventional coating method. Among them, a layer consisting of a deposited film such as a vapor deposited film, a coating film, a dipping film, or a laminate is preferred. The thickness of the A layer and the B layer is preferably in the range of 200 Å to 10 μm, preferably in the range of 1000 Å to 1 μm, regardless of whether a monomolecular film, a cumulative film thereof, or a deposited film is used. On the other hand, when using a monomolecular film or a cumulative film thereof, the thickness of the light absorption layer is preferably in the range of 30 Å to 1000 Å, preferably in the range of 50 Å to 200 Å,
When a deposited film is used, the thickness is preferably in the range of 90 Å to 1000 Å, preferably in the range of 140 Å to 400 Å. In addition, materials used for the substrate in the present invention include semiconductor materials such as silicon, metal materials such as aluminum, preferably reinforced glass, and more preferably acrylic (PMMA), polycarbonate (PC), polypropylene, and polychloride. Plastic materials such as vinyl (PVC) and polystyrene, and ceramic materials are preferred. As mentioned above, the optical recording element used in the present invention is
One feature is that at least one of the A layer containing a color-forming compound, the B layer containing an auxochrome compound, and the light absorption layer is composed of a monomolecular film of a constituent material or a cumulative film thereof. . As a method for creating a monomolecular film or a cumulative film thereof having such high orderliness and high orientation of molecules,
For example, Langmuir developed by I.Langmuir et al.
The Blodget method (LB method) is used. The Langmiur-Blodget method is based on the Langmiur-Blodget method, in which, for example, in a molecule with a structure that has a hydrophilic group and a hydrophobic group within the molecule, when the balance between the two (balance of amphiphilicity) is maintained appropriately, the molecule lowers the hydrophilic group on the water surface. This is a method of creating a monomolecular film or a cumulative film of monomolecular molecules by utilizing the fact that they form a monomolecular layer toward the target. A monolayer on the water surface has the characteristics of a two-dimensional system. When the molecules are sparsely dispersed, the area per molecule A and the surface pressure Π
The equation for a two-dimensional ideal gas, ΠA=kT, holds between and becomes a "gas film". Here, k is Boltzmann's constant and T is absolute temperature. If A is made sufficiently small, the intermolecular interaction will be strengthened, resulting in a two-dimensional solid "condensation film (or solid film)". The condensed film can be transferred layer by layer onto the surface of carriers having various materials and shapes, such as plastic substrates and glass substrates. Next, a method for forming a monomolecular film of an organic molecule having both a hydrophilic group and a hydrophobic group, which is a chromogenic compound, an auxochrome compound, or a light-absorbing substance used in the present invention, or a cumulative film thereof will be described in further detail. First, the organic molecule is dissolved in a volatile solvent such as benzene, chloroform, etc., and spread on the aqueous phase 11 in the water tank 10 of the monomolecular cumulative film forming apparatus schematically shown in FIG. 3 using a cylinder or the like. As the solvent evaporates, the organic molecule has 1 hydrophilic group.
2 is directed toward the aqueous phase, and the hydrophobic group 13 is developed onto the aqueous phase 11 with the hydrophobic group 13 directed toward the gas phase. Next, in order to prevent the precipitates (organic molecules) from freely diffusing on the aqueous phase 11 and spreading too much, a partition plate (or float) 14 is provided to limit the spread area and control the aggregation state of the membrane substance. Obtain the surface pressure Π proportional to the collective state. By moving the partition plate 14, the developed area can be reduced to control the aggregation state of the film material, and the surface pressure can be gradually increased to set the surface pressure Π suitable for producing a cumulative film. By gently vertically moving the clean substrate 14 up and down while maintaining this surface pressure, the monomolecular film 16 is transferred onto the substrate. The monomolecular layer 16 is manufactured in the above manner, and the monomolecular phase cumulative film 17 is formed by repeating the above operations to form a desired cumulative number of monomolecular layer cumulative films. For example, when a substrate 15 with a hydrophilic surface is pulled out of water in a direction across the water surface, a monomolecular layer 16 with the hydrophilic groups of the organic molecules facing the substrate 15 is formed on the substrate 15.
Formed on 5. When the substrate 15 is moved up and down as described above, the monomolecular layers 16 are stacked one by one in each step. Since the orientation of the film-forming molecules is reversed between the pulling process and the dipping process, this method forms a so-called Y-shaped film in which the hydrophilic groups of the organic molecules face each other, and the hydrophobic groups of the organic molecules face each other between the layers. (Figure 4a). The Y-type film is strong because the hydrophilic groups and hydrophobic groups of the organic molecules face each other. On the other hand, there is also a method in which the organic molecules are transferred to the substrate surface only when the substrate 15 is lowered into water. In this method, even if accumulated, there is no change in the direction of the film-forming molecules, and in all layers, the hydrophobic groups are on the substrate 15.
A side-facing X-shaped membrane is formed (FIG. 4b). On the other hand, a cumulative film in which the hydrophilic groups in all layers face the substrate 15 side is called a Z-type film (FIG. 4c). The Z-type film is obtained by transferring organic molecules onto the surface of the substrate only when the substrate 15 is lifted out of the water. The monomolecular film and monomolecular layer stack formed on the substrate by the above method have high density and a high degree of order and orientation, and these films can constitute the recording layer. Accordingly, a recording element having a high-density, high-resolution recording function that is possible with photothermal recording can be obtained. Further, as can be seen from the principle, these film forming methods are very simple methods, and a recording element having the above-mentioned excellent recording function can be provided at low cost. The substrate on which the monomolecular film or monomolecular cumulative film in the present invention is formed as described above is not particularly limited, but if a surfactant is attached to the surface of the substrate,
When the monomolecular layer is transferred from the water surface, the monomolecular film is disturbed and a good monomolecular film or monomolecular layer accumulation film cannot be formed, so it is necessary to use a substrate with a clean surface. The monomolecular film or monomolecular layer accumulation film on the substrate is sufficiently strongly fixed and rarely peels or peels off from the substrate. An adhesive layer can also be provided between the layer stacks. Furthermore, the adhesion force can be strengthened by selecting the monomolecular layer formation conditions, such as the hydrogen ion concentration of the aqueous phase, the ion species, the water temperature, the rate of raising and lowering the carrier, or the surface pressure. Next, the deposited film and the formation method of layer A, layer B, or light absorption layer are as follows: A water mixture obtained by adding a binder and water to the above-mentioned color-forming compound, auxochrome compound, or light-absorbing substance is mixed with a ball mill or the like. After pulverizing and mixing, it is applied onto a substrate or the like using a conventional method. The binder used in the present invention includes natural polymers such as gelatin and starch, cellulose derivatives such as nitrate woven cellulose and carboxymethyl cellulose, and semi-synthetic polymers such as natural rubber plastics such as chlorinated rubber and cyclized rubber. Molecular substances, polyisobutylene, polystyrene, terpene resin, polyacrylic acid, polyacrylic ester, polymethacrylic ester, polyacrylonitrile, polyacrylamide, polyvinyl acetate, polyvinyl alcohol, polyvinylpyrrolidone, polyacetal resin, polyvinyl chloride , polyvinylpyridine, polyvinylcarbazole, polybutadiene, polystyrene-butadiene, butyl rubber, polyoxymethylene, polyethyleneimine, polyethyleneimine hydrochloride, poly(2-acryloxyethyldimethylsulfonium chloride), etc., polymerizable synthetic polymers, phenolic resins, Condensation polymerization type synthetic polymers such as amino resin, toluene resin, alkyd resin, unsaturated polyester resin, allyl resin, polycarbonate, polyamide resin, polyether resin, silicon resin, furan resin, thiol rubber, etc., polyurethane, polyurea, epoxy resin Examples include addition polymerization type resins such as. As a method for forming the reflective layer in the present invention, conventional methods can be used, and among these, vacuum evaporation, sputtering, etc. are preferable. In addition, the method for forming the protective layer in the present invention can be any conventionally practiced method, including, for example, plasma CVD method, photo CVD method,
A vacuum deposition method, a sputtering method, a coating method, etc. are preferred. The optical recording element according to the present invention can be easily manufactured by sequentially combining the methods for forming each layer described above according to the intended structure. Next, embodiments of the structure of the optical recording element used in the present invention will be shown below. () Figure 5 a shows an example of an embodiment, which is composed of an A layer 2 containing a color-forming compound, a B layer 4 containing an auxochrome compound, and a light absorption layer 3 interposed between the A layer and the B layer. A laminate is supported on the substrate 1 via the B layer 4 and laminated in the order of substrate/B layer/light absorption layer/A layer. Furthermore, as another example, the A layer of the laminate may be supported on a substrate, and the laminate may be laminated in the order of substrate/A layer/light absorption layer/B layer, or the laminate may be stacked in two or more stages so that the bottom layer is Layer A or layer B may be supported on the substrate. In the above configuration, the A layer and B layer of the laminate
At least one of the layers and the light absorption layer is formed of a monomolecular film of each constituent material or a cumulative film thereof, and the other layers are formed of deposited films or the like. Specific examples thereof are as follows. (1) The A layer, the B layer, and the light absorption layer are all monomolecular films or their cumulative film (hereinafter referred to as "LB film"). (2) The A layer, the light absorption layer are LB films, and the B layer is a deposited film. (3) Light absorption film, B layer is LB film, A layer is deposited film (4) A layer, B layer is LB film, light absorption layer is deposited film (5) A layer is LB film, B layer is light absorption The layer is a deposited film (6) The light absorption layer is a LB film, the A layer, and the B layer are deposited films. (7) The B layer is an LB film, the A layer, and the light absorption layer are deposited films. Since the optical recording element used is constructed by separating layers A and B by a light absorption layer, the light absorption layer can be melted or sublimated by infrared irradiation to create holes at desired positions. As a result, the color-forming compound of layer A comes into contact with the auxochrome compound of layer B, a color-forming reaction progresses, and a color-forming point is formed at the position, thereby making it possible to record information. () Figure 5b shows a laminate in which a layer A 2 containing a color-forming compound and a layer B 4 containing an auxochrome compound are laminated, and a light absorption layer 3 is further provided on the layer B 4. It is supported on a substrate 1 via the light absorption layer 3, and is laminated in the order of substrate/light absorption layer/B layer/A layer. In this case, the A layer 2 and the B layer 4 may be reversed and laminated in the order of substrate/light absorption layer/A layer/B layer. Furthermore, to show another example, as shown in FIG.
The B layer 4 is supported on the substrate 1, and the substrate/B layer/A
It is formed by laminating layers/light absorption layer in this order.
In this case, similarly to the above, the A layer 2 and the B layer 4 may be reversed and laminated in the order of substrate/A layer/B layer/light absorption layer. Furthermore, in any of the configurations shown in FIGS. 5b and 5c, the laminates may be stacked in two or more stages and supported on the substrate. In the configuration () above, A of the laminate
At least one layer among the B layer and the light absorption layer is formed of a monomolecular film of each constituent material or a cumulative film thereof, and the subsequent layers are formed of deposited films. To give a specific example, (1) of the above embodiment ()
- As described in (7). The optical recording element having the structure () above is constructed by closely adhering the A layer made of a color-forming compound and the B layer made of an auxochrome compound, but such a structure is not possible with conventional technology. It was considered possible. However, in the present invention, since the A layer and/or the B layer are formed of a monolayer having a high degree of molecular order and orientation and a cumulative film thereof, The above configuration was made possible because the reactive sites could be separated from each other. Furthermore, since the optical recording element used in the present invention having the structure () above is constructed by laminating layers A and B in close contact with each other and further providing a light absorption layer on the outside, it is possible to The light absorption layer is then heated, and due to the heat conduction, the color-forming compound of the A layer and the B layer are heated.
A coloring reaction progresses through heating contact with the auxochromic compound in the layer, forming coloring points at predetermined positions and allowing information to be recorded. In this case, non-melting dyes and non-sublimating dyes are suitable as the light-absorbing substance.

From the results in Table 2, when comparing No. 1 (when the light absorption layer is made of a monomolecular film) and No. 11, it is recognized that No. 1 is significantly superior in signal/noise ratio. Although No. 1 and No. 11 have almost the same thickness of each layer, the difference in performance appears to be because No. 1 has fewer defects such as pinholes. Similarly, in comparing No. 2 to No. 10 (when the light absorption layer is composed of a monomolecular cumulative film) and No. 12, No. 2 to No.
It is recognized that 10 is superior in signal/noise ratio. [Invention and Effects] As explained above, in the information processing device according to the present invention, at least one layer among the A layer, the B layer, and the light absorption layer is composed of a monomolecular film of a constituent material or a layer consisting of a cumulative film thereof. Since the optical recording element is used, there are excellent effects as shown below. (1) Compared to optical recording elements that do not use conventional monomolecular films or their cumulative films, the signal/noise ratio is higher and the reliability of recording can be improved. (2) Physical defects such as pinholes in optical recording elements can be significantly reduced. (3) Higher density recording is possible than with conventional optical recording elements. (4) It is possible to increase the area of the optical recording element. (5) When the light absorbing layer is not interposed between the A layer and the B layer, color development efficiency and fidelity are improved. (6) By adopting a configuration in which the light absorption layer is not interposed between the A layer and the B layer, the recording layer can be made thinner, and higher density recording becomes possible. (7) Chemically changes (synthesizes) materials that have good coloring efficiency and are excellent as coloring agents, but are difficult to form monomolecular films or their cumulative films, or derivatives that are easy to form monomolecular films or their cumulative films. There is an advantage that materials which are difficult to manufacture due to cost can be used for the deposited film. (8) Since a deposited film is used in a part of the laminate, sensitivity is improved, material selection and width are wide, and manufacturing is easy, and there is no difference between contrast and non-contrast during reading. It has effects on optical properties such as easy adhesion.
