[Embodiment] 1 is a perspective view of a degaussing device 1 of a first embodiment, FIG. 2 is a perspective view of an internal structure of the degaussing device 1, and FIG. 3 is an explanatory view of a magnetic field direction. 1 is a casing 2 having a rectangular box shape. An opening 4 is provided in the center of the front surface of the casing 0 2, and an operation button 3 is provided on the upper left side thereof. The opening 4 is a surface of the bottom sill 5 housed inside. The cover 7 is plugged. The center of the surface cover 7 is provided with a handle 6 which protrudes toward the front.

Further, the recording medium accommodating case 8 can receive the hard disk 9 or the like from the upper opening portion thereof. Magnetic recording media. On the inner side of the opening portion 4 (refer to FIG. 1) on the front surface of the casing 2, the insertion hole portion 11 into which the recording medium storage case 8 of the substrate g 5 is inserted and removed is provided. A plurality of coils 21a to 29b (not shown) are disposed in the vicinity of the side surface of one side of the insertion hole portion 11, that is, nine coils 21a to 29a are arranged in a matrix of three equal intervals. The nine coils 21a to 29a are arranged in the left-right direction (width direction), and the arrangement of the magnetic directions of all the coils 21a to 29a of the nine coils 21a to 29a is the same.
於插人孔部11之另一側面之左側面，亦以9個線圈 21b〜29b(省略圖示）與上述線圈21a〜29a相同之配置，使 左右對稱。因此，線圈21a〜29b亦配置成前後上下各3 個等間隔之矩陣狀。又，線圈21a〜29b皆以軸朝左右方向 (寬度方向）配置。又，線圈21a〜29b之所有線圈21b〜29b 之磁場方向與上述線圈21a〜29a之配置相同。 又，·隔著***孔部11而相對之線圈21a與線圈21b， 其構成乃為1對之線圈對21。同樣地，隔著***孔部n 而相對之全部線圈22a〜29a、22b〜29b(省略圖示），以符 號「a」與符號「b」為一對而構成線圈對22〜29。對此線 圈對21〜29所配置之成對線圈間之空隙間隔L全部相同。 線圈對21藉由於線圈…、21b所通過之相同方向之 電流1 如圖3所示，產生磁場方向G.之磁力。在此， 線圈21 a .、2lb之車由s灸·in mt 孕 為相同亚磁性串聯配置。因此，後 圈21a、21b如為！桐紿m上 、、承 ”、、们、、表圈般，於線圈對21整體產生磁場 方向之磁力。因此，***孔部ιι(與***於此内部之記 200809799 錄媒體收容盒8内之硬碟9)於線圈對21中位於磁力最高 之線圈21a與線圈21b間，以接收到強大磁力。 圖4係頒示消磁裝置1之電路方塊圖。 消磁裝置1連接至交流電源45。於此交流電源45後 段，設有與操作按紐3(參考圖υ連動之操作開關46。於此 ‘作開關46之後段設有整流電^ 44。此整流電路為藉 由二極體橋等之交流電壓全波整流電路。X，於該整流電 路44亦可設置適當之電源變壓器等。 於整流電路44徭與，泰六^ 聯。於電容tin磁二;^ 43與磁場產生部20並 消磁開關4 2藉由省略二：間設置消磁開關4 2。此 磁埸姦 圖不之蚪序電路以控制ΟΝ/OFF。 磁％·產生部2〇女、—a,, 對21〜29分別連接開：3二圈對21〜29並聯。各線圈 線圈對21之線圈21a、2]h炎+ 圈對22〜29亦為成· b為黾性亚聯。同樣地，線 性並聯。 對之2個線圈22a〜29a、22b〜29b電 開關31〜39藉由診'接於省略圖示之切換控制電路。各 ΟΝ/OFF。藉由換控制電路之控伽執行個別切換 圈對21〜29中 制電路之⑽OFF控制，係依據線 ΟΝ/OFF，或於線隱敏 刀隔以母數個一組依序執行切換 於物理性分隔 > 乂 一個個執行切換0N/0FF。 時，例如，可將最之每數個一組依序執行切換ON/OFF ON，接著僅有線圈線圈對21、23、25、27、29為 24、26、28為QN予以具體化。 200809799 其他亦可僅使線圈對21、23為ON，接著僅有線圈對 24、26為ON ’接著僅有線圈對27、29為on，接著僅有 線圈對22、28為ON，最後僅有線圈對25為ON予以具 體化。又，此切換控制電路之控制構成亦可為包含上述時 序電路之消磁開關420N/0FF。 對於如此物理性分隔之線圈對於同時產生磁場時，由 於線圈對為分離狀態，因此可抑制彼此磁場之相互干涉， 而有效地消磁。又，相較於每個線圈對之依序執行，更可 於短時間結束硬碟9整體之消磁。 藉由以上構成，使用者可握住把手6拉出隔底匣5， 於記錄媒體收容盒8中放人欲;肖除磁㈣訊(欲消磁）之硬 碟9，將隔底匣5之記錄媒體收容盒8部分往***孔部u ***到底，操作按鈕3 一按，即可啟動消磁裝置i之消磁 並為^裝诗鈕3按下時絲轉作開關46 電。此時，1^= 4241之電壓全波整流向電容器43充 了肩磁開關42為OFF狀態。 田絰過_定時間，藉由省略 磁開關42從0FF切施支⑽ 町斤包硌之驅動，消 換為〇Ν，而將蓄積於電容ρ 43 > + 壓鉍加於磁場產生部2〇。 之電 、每產生部20藉由省略圖示切掩_制 31^39 ^ 開關31〜39相 刀·、、、，電谷斋43對與為ON之 ^ 相對應之線圈對21〜29之線圈2la〜29h π + 施加電摩。 α 29b同時 11 200809799 此時，線圈21 a〜29b每個產生約1萬高斯之磁場，而 線圈對21〜四因係為2個線圈21a〜29b以每2個磁性串 聯於軸S上所成，故1個線圈對整體可產生約1.5·萬高斯 磁場。因此，相較於利用1個線圈產生1.5萬高斯磁場， 可於低.電壓使線圈對產生1.5萬高斯之磁場。 在此，對電容器43施加電壓，可藉由開關31〜39之 ON快速進行。又，由於電容器43與線圈21a〜29b構成 共振電路，因此通過線圈21a〜29b之電流於正負交替變換 同時，波高值會隨著時間經過而缓慢下降成為衰減交流 電。因此，藉由線圈21a〜29b所產生之磁場，當磁極於正 負交替變換同時，磁束密度會緩慢下降而成為衰減交流磁 場。於是，硬碟9内之磁碟中受到衰減交替磁場之區域會 因被消磁而消除此區域之磁性貧訊。 又，於時序電路與切換控制電路，對於所有線圈對21 〜29依序重複至上述行動執行為止；對於硬碟9之所有區 域，則藉由消磁執行磁性資訊之消除。 如此，如圖5之說明圖之(A)所示，於硬碟9(參考圖 2)之磁碟D以水平方式記錄磁性資訊J時，以通過線圈對 21之磁場方向G的磁力而如圖5(B)所示進行消磁。藉此， 可消除磁性資訊J。 又，如圖5(C)所示，於硬碟9(參考圖2)之磁氣光碟D 以垂直方式記錄磁性資訊J時，亦可以通過對線圈21之磁 場方向G的磁力而如圖5之(D)所示進行消磁。特別是， 於如此以垂直方式記錄磁性資訊J時，本實施例之消磁裝 12 200809799 置1可起有效作用。 又，於上述實施例中，線圈對21〜29之數目為9個， 然亦可不限於此而以其他複數個進行。於此情形時，亦可 達到相同效果。 又，於線圈對21〜29，以每複數組施加電壓於部分單 位進行消磁時，其構成亦可為以相同組數之線圈對單位依 序施加電壓。此時，因可將切換施加之電壓總是設為相同 電壓，故可將電路簡略化^On the left side surface of the other side surface of the insertion hole portion 11, the nine coils 21b to 29b (not shown) are arranged in the same manner as the coils 21a to 29a, and are bilaterally symmetrical. Therefore, the coils 21a to 29b are also arranged in a matrix shape of three equal intervals. Further, the coils 21a to 29b are arranged such that the axes are oriented in the left-right direction (width direction). Further, the magnetic field directions of all the coils 21b to 29b of the coils 21a to 29b are the same as those of the coils 21a to 29a. Further, the coil 21a and the coil 21b which are opposed to each other via the insertion hole portion 11 are configured as a pair of coil pairs 21. Similarly, all of the coils 22a to 29a and 22b to 29b (not shown) are opposed to each other via the insertion hole portion n, and the pair of symbols "a" and "b" are paired to form the pair of coils 22 to 29. The gap intervals L between the pair of coils to which the coil pairs 21 to 29 are arranged are all the same. The coil pair 21 is caused by the current in the same direction through which the coils ..., 21b pass, as shown in Fig. 3, and generates a magnetic force in the direction of the magnetic field G. Here, the coil 21 a., 2 lb of the vehicle is configured by the same sub-magnetic series by the s moxibustion. Therefore, the rear rings 21a, 21b are as follows! In the case of the Tonglu m, the bearing, the ",", and the bezel, the magnetic force of the magnetic field direction is generated in the coil pair 21 as a whole. Therefore, the insertion hole portion ιι (with the insertion into the internal memory of the 200809799 recording medium storage box 8) The hard disk 9) is located between the coil 21a and the coil 21b having the highest magnetic force in the coil pair 21 to receive a strong magnetic force. Fig. 4 is a circuit block diagram showing the degaussing device 1. The degaussing device 1 is connected to an AC power source 45. The rear part of the AC power supply 45 is provided with an operation button 3 (refer to the figure υ linkage operation switch 46. Here, the rectification electric power is provided in the rear section of the switch 46. The rectification circuit is an exchange by a diode bridge or the like. The voltage full-wave rectifying circuit X, in the rectifying circuit 44, may also be provided with a suitable power transformer, etc. in the rectifying circuit 44 徭 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , 4 2 By omitting the two: setting the degaussing switch 4 2. This magnetic smashing circuit does not control the circuit to control ΟΝ / OFF.

Each coil coil pair 21 coil 21a, 2] h inflammation + The circle pairs 22 to 29 are also the same as the b-type sub-links. Similarly, the linear parallel connection. The two coils 22a to 29a, 22b to 29b, the electric switches 31 to 39 are switched by the diagnosis. Control circuit, each ΟΝ/OFF. The (10) OFF control of the circuit in the 21~29 circuit is performed by the control gamma of the control circuit, according to the line OFF/OFF, or the line hidden sensitive knife is separated by the number of the mother The group performs the switching to the physical separation in sequence, and performs the switching 0N/0FF one by one. For example, the switching of the most recent groups can be performed ON/OFF ON sequentially, and then only the coil coil pair 21, 23, 25, 27, and 29 are 24, 26, and 28 for the QN to be embodied. 200809799 Others may only make the coil pairs 21, 23 ON, then only the coil pairs 24, 26 are ON' and then only the coil pair 27 29 is on, then only the coil pair 22, 28 is ON, and finally only the coil pair 25 is turned on. Further, the control structure of the switching control circuit may also be the degaussing switch 420N/0FF including the above sequential circuit. For such physically separated coils, when the magnetic field is generated simultaneously, the coil pairs are separated. Therefore, the mutual interference of the magnetic fields of each other can be suppressed, and the degaussing can be effectively performed. Further, the degaussing of the entire hard disk 9 can be ended in a short time compared to the sequential execution of each coil pair. Holding the handle 6 and pulling out the bottom 匣 5, placing the human in the recording medium storage box 8; removing the hard disk 9 of the magnetic (four) signal (to be demagnetized), inserting the recording medium storage box 8 of the bottom 匣 5 into the The hole portion u is inserted into the bottom, and the operation button 3 is pressed to start the degaussing of the degaussing device i and the wire is turned into the switch 46 when the button 10 is pressed. At this time, the voltage full-wave rectification of 1^= 4241 supplies the capacitor 43 with the shoulder magnetic switch 42 in the OFF state. The field 绖 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Hey. The electric power and the generating unit 20 are omitted from the illustrations by the omission of the illustrations 31 to 39 ^ The switches 31 to 39 are connected to each other, and the electric grids 43 are paired with the pair of coils 21 to 29 which are ON. The coils 2la to 29h π + apply electric friction. α 29b at the same time 11 200809799 At this time, the coils 21 a to 29b each generate a magnetic field of about 10,000 Gauss, and the coil pairs 21 to 4 are two coils 21a to 29b which are formed by connecting each of the two magnetic series on the axis S. Therefore, one coil pair can generate a magnetic field of about 1.5 million Gauss. Therefore, compared to the use of 1 coil to generate 15,000 Gaussian magnetic field, the coil pair can generate a magnetic field of 15,000 Gauss at a low voltage. Here, applying a voltage to the capacitor 43 can be quickly performed by ON of the switches 31 to 39. Further, since the capacitor 43 and the coils 21a to 29b constitute a resonance circuit, the currents passing through the coils 21a to 29b are alternately converted between positive and negative, and the wave height value gradually decreases with time to become an attenuated alternating current. Therefore, by the magnetic field generated by the coils 21a to 29b, when the magnetic poles alternate between positive and negative, the magnetic flux density gradually decreases to become an attenuated alternating magnetic field. Thus, the area of the disk in the hard disk 9 that is subjected to the decaying alternating magnetic field is demagnetized to eliminate the magnetic poorness in this area. Further, in the sequential circuit and the switching control circuit, all of the coil pairs 21 to 29 are sequentially repeated until the above-described action is performed; for all areas of the hard disk 9, the magnetic information is eliminated by degaussing. Thus, as shown in FIG. 5 (A), when the magnetic disk D of the hard disk 9 (refer to FIG. 2) records the magnetic information J in a horizontal manner, the magnetic force passing through the magnetic field direction G of the coil pair 21 is as Degaussing is performed as shown in Fig. 5(B). Thereby, the magnetic information J can be eliminated. Further, as shown in FIG. 5(C), when the magnetic optical disc D of the hard disk 9 (refer to FIG. 2) records the magnetic information J in a vertical manner, it is also possible to pass the magnetic force of the magnetic field direction G of the coil 21 as shown in FIG. Degaussing is performed as shown in (D). In particular, when the magnetic information J is thus recorded in a vertical manner, the degaussing device 12 200809799 of the present embodiment can be effectively used. Further, in the above embodiment, the number of the pair of coils 21 to 29 is nine, but it is not limited thereto and may be performed in other plural. In this case, the same effect can be achieved. Further, when the pair of coils 21 to 29 are demagnetized by applying a voltage to each unit in a plurality of arrays, the voltage may be applied in the same order by the number of coil pairs. At this time, since the voltage applied by the switching can always be set to the same voltage, the circuit can be simplified.

However, the four coils may be arranged in a magnetic arrangement in series to form one coil pair, that is, It is also possible to form a coil pair by a plurality of other coil groups. At this time, the insertion hole portion 11 is provided in the central portion of the plurality of coils connected in series, and the same effect can be obtained. [Embodiment 2] In the insertion hole portion 11A, the coils 21a to 23b are disposed in a different magnetic field. Circle pairs 21~23. Fig. 6 is a perspective view showing the internal structure of the degaussing device X1A of the second embodiment. The degaussing device 1A has a spherical shape and has an inner hollow insertion hole portion UA. The opening portion provided on the front surface of the degaussing device 1A can be operated by the pivoting portion 10A. The direction and the XYZ direction of the 3rd dimension are mutually arranged. The coils 21a to 23b respectively constitute a line. The degaussing apparatus 1A is provided with a box-shaped housing which is not scented by the syllabary-^^^ sentence, and is provided with a thumbnail on the front side. Operation button. Further, in addition, the magnetic magnetic device 1A has the above-described insertion hole portion or the like inside the casing. 13 200809799 The circuit configuration of the degaussing device 1A is the same as that of the first embodiment except that the number of the coil pairs 21 to 29 and the switches 31 to 39 of the magnetic field generating portion 20 (refer to Fig. 4) is different. With the above configuration, the user opens the surface cover 7A, inserts a magnetic recording medium such as a micro-driver 9A having a small hard disk into the insertion hole portion 11A as indicated by a broken line, and covers the surface cover 7A, and presses the operation omitted from the illustration. With the button, the degaussing device 1A can be activated to start the degaussing action. The degaussing device 1A generates a magnetic force in the X direction, the Y direction, and the Z direction by the coil pair 21 to 23. Therefore, the magnetic information of the micro-actuator 9A inserted into the insertion hole portion 11A can be surely eliminated. That is, with respect to the micro-driver 9 A, since the magnetic force can be irradiated from various directions, it is possible to prevent a part of the residual from occurring due to the failure to completely eliminate the time information. Further, in the second embodiment, the number of coil pairs is three, but the present invention is not limited thereto, and a plurality of components may be arranged in a spherical shape around the insertion hole portion 11. The same effect can be obtained in the case. [Embodiment 3] Next, a description will be given of a demagnetization device 1B of Embodiment 3 and a perspective view of Fig. 7. The degaussing device 1B is the same as the first embodiment except for the arrangement of the coils 21a and 21b, and the same reference numerals are given to the same members, and the detailed description thereof will be omitted. Around the insertion hole portion 11, the coils 21a and 21b are magnetically arranged in series on the shaft S in the direction in which the bottom cymbal 5 is inserted. Therefore, the insertion hole portion 11 is provided in the shaft of the coils 21a and 21b. The coils 21a and 21b are configured as a coil pair 14 having the same magnetic direction. The circuit structure of the degaussing device 1B is not opened 31 to 39 except for the magnetic field generating portion 2 (refer to FIG. 4), and the coil pairs 21 to 29 are only The first coil pair 21 is the same as that of the first embodiment, and thus detailed description thereof will be omitted. According to the above configuration, as in the first embodiment, a strong magnetic force can be generated at a low voltage to achieve a demagnetization effect. Further, in the third embodiment, the coil pair 21 uses two coils 21a and 21b. Alternatively, three or more coils may be magnetically arranged in series, that is, a plurality of other pairs may be aligned. This situation can also achieve the same effect. Further, the configuration of each of the above embodiments is such that the AC voltage full-wave rectification is in the form of a direct current. However, the present invention is not limited thereto, and the configuration may be an alternating current. In this case, the current through each coil can be set to positive and negative alternately = alternating current, and the magnetic pole can be set to positive and negative = alternating magnetic field by the magnetic field generated by each coil. Further, if the applied AC voltage is gradually attenuated, the current passing through each coil can be attenuated as an alternating current, and the alternating magnetic field can be generated by each coil. [Embodiment 4] Other embodiments will be described with respect to the connection of each coil.

The magnetic properties recorded by the recording medium are recorded by the strong magnetic direction in this direction. Fig. _ is an example in which the coils 21a, 21b are electrically connected in series. In the shape of the horizontal hole portion u sandwiched between the coils 21a, 21b, a direction is obtained. In particular, since the coils 21a, 2bb are connected in series, it is possible to generate a magnetic field synchronously with the magnetic field. Therefore, it is possible to easily obtain a strong magnetic force in one direction by using the multiplication effect of the coiling, the hunger, and the field. By hunting the strong magnetic force in one direction, the magnetic data recorded by the magnetic recording medium inserted into the horizontal hole u can be eliminated. Figure 8 (C) is the coil 2la, ? 1h ® 91 91K is a private sub-continent, and it turns from the magnetic field of each line to the reverse. At this time, the magnetic field of the magnetic field P is collided with the horizontal hole U, and the magnetic force recorded by the magnetic recording medium inserted into the horizontal hole 11 can be eliminated by the magnetic force of the disorder. Fig. 9(A) shows an example in which the switch 41 for switching to the same direction by the coil d is provided. At this time, as shown in Fig. S, if the closing 41 is connected to the contact on the - side, the current passed by the coil 21b will be in the same direction as the coil 21a, and a magnetic field will be generated in the same direction. By this, a strong magnetic field in the direction of the horizontal hole portion 11 can be obtained, and the recording of the magnetic recording medium received in the horizontal hole portion η can be eliminated. As shown in Fig. 9(B), if the switch 41 is connected to the contact on the other side, the current passed by the collar will be opposite to the reverse of the coil 2U, and the magnetic Lb will be generated in the opposite direction. U causes the magnetic fields to collide, and the magnetic material of the magnetic recording medium accommodated in the horizontal hole portion 11 can be eliminated. Thus, by switching the positive and negative switching of the direction of current flow by the switch 41, the magnetic fields respectively generated by the coils 16 200809799 21a, 21b can be switched in the same direction or in the opposite direction. Moreover, if the switching is performed several times, the magnetic data can be virtually eliminated by performing magnetic interaction by the magnetic field in the same direction and the magnetic data elimination by the collision magnetic field.

Around the insertion hole portion 111, a coil 112 is disposed in the direction of the axis S in the direction in which the bottom sill 105 is inserted. Therefore, the insertion hole portion 111 is provided in the shaft of the coil 112. The coil 112 can generate a magnetic force in the direction of the magnetic field G from the front side to the back side. 17 200809799 In addition, this reverse magnetic field can also be generated.

Further, the inner surface of the inner casing 133 has a larger front and rear direction and a vertical direction than the hard disk 139. Thereby, the hard disk 139 can move back and forth in the inner box 133. Further, the cushioning material 131 placed on the hard disk 139 can be prevented from falling out of the inner casing 133. 18 200809799 On the outer side of the left and right sides of the inner box 133, the left and right symmetrical adjustment protrusions 134 are provided at the center.

A polarity inversion reverse switching switch 142 and a degaussing switch 141 are provided between the capacitor 1 § 143 and the coil 112. The polarity inverting switch 142 performs switching control by a switching control circuit (not shown). Thereby, the polarity inverting switch I" can positively and negatively switch the polarity direction from the discharge of the capacitor 143 to the coil 112. Further, the degaussing switch 141 performs ΟΝ/OFF control by switching the fish terminal circuit (not shown). Fig. 15 is a flow chart showing the execution of the degaussing device 101.

However, the shape of the spherical shape is not limited to the form of embedding, and the position of the inner two (3) hard disk 139 does not move back and forth. In addition, a voltage is applied to the capacitor U3, which can be quickly driven by the degaussing switch 14] ON. Since the capacitor 143 and the coil 112 form a resonance electric current, the current passing through the coil 112 alternates between positive and negative, and the private slow decline with time. Become attenuated AC. Therefore, with the magnetic field generated by 2009709799 112, when the magnetic pole alternates between positive and negative, the magnetic flux density will slowly decrease and become an attenuated alternating magnetic field. Thus, the area of the 2 disks 139a in the hard disk 139 that is subjected to the attenuation of the alternating magnetic field (all areas other than the shaded area E1) is demagnetized to eliminate the magnetic information of the area. ★ Next, the degaussing device 101 starts to charge the capacitor 143 again (step ^ and the field voltage state 143 is fully charged, then the polarity is reversed by switching the polarity control switch 142, and by the sequential circuit, The storage voltage of the capacitor 143 is turned to the second direction (the direction of the arrow b in Fig. u) (step S5). At this time, the magnetic field flows in the direction of the arrow B shown in Fig. 17, as shown in Fig. 16(b) = explanatory diagram It is shown that the magnetic disk 139a in the hard disk 139 is demagnetized by the magnetic field Gb in a portion other than the shadow area. Further, the metal hard disk 139 is shown by the magnetic field Gb as shown in the right side of the longitudinal section of Fig. 18. At this time, since the cushioning material 131 is present, the hard disk 139 cannot move to the front side in the inner casing 133, but moves entirely inside the inner casing 133. Although the inner casing 133 is positive with the outer casing 108 The panel 10a is in conflict with each other, but the shock can be relieved by the cushioning material m. Further, by the inner casing 133 moving toward the front side, the back side of the inner casing 133 is detached from the support projection 125. The disc 139 is located in the inner box 133. After the square, the center of gravity is located further behind the branch #axis 123, and the inner box 133 Rotating backward and downward by gravity, about 30. The downward tilting state is supported by the support shaft 123. At this time, the position of the adjustment protrusion 134 is located at the central curved portion of the adjustment guide 124. Next, the degaussing device 101 performs again. The capacitor 143 is charged (step 21 200809799 S6). Further, when the capacitor 143 is fully charged, the polarity reversing switch 142 is switched by the switching control circuit to return the polarity reversal to the initial state again, by the sequential circuit 'the storage voltage of the capacitor 143' The third direction (the direction of the arrow C in the figure) is discharged (step S7). At this time, the magnetic field flows in the direction of the arrow c shown in Fig. 18, and the magnetic field in the hard disk 139 is shown in the explanatory diagram of Fig. 16(C). The disk 139a is demagnetized by a magnetic field Gc in a portion other than the shaded area E3. Further, the metal hard disk 139 is moved to the back side by the magnetic field Gc and the inner case 133, and the buffer member 126 is provided to relieve the impact. By the above operation, the magnetic disk 139 can be irradiated with magnetic % from the three directions in sequence, and the magnetic information recorded on the magnetic disk 139a can be eliminated. Since the magnetic disk 139a is rotationally driven, the rotary driving portion 139b is provided at the center. The magnetic field irradiation in the i direction can generate the magnetic field yoke by rotating the driving portion 139b, and the magnetic field is irradiated by the magnetic field irradiation from other directions, thereby completely eliminating the magnetic information. In this embodiment, By irradiating the magnetic field from the three directions, as shown in the explanatory diagram of Fig. 19, all overlapping regions of the shaded regions El E2 and E3 are zeroed, and the magnetic information can be surely eliminated. Further, in this embodiment, metal is made. The hard disk 139 can be switched between the positive and negative directions of the magnetic field irradiation only by the force of the magnetic flux, and the angle at which the hard disk 139 is irradiated with the magnetic field can be switched. Therefore, for example, if the angle of 1% of the hard disk is gradually changed to a specified angle with the device/input motor, the comparison can be made at a lower price. Moreover, since it is not necessary to connect the stepping motor to a 'brake' angle circuit, the circuit structure can be simplified, and this can also reduce the cost of 200809799. In addition, the capacitor 143 cannot be charged during the passage of the stepping motor current due to the angle change, so that the magnetic information can be eliminated in a short time. In addition, there is no need to consider that the stepper motor or its control circuit is affected by the strong magnetic field used to eliminate the magnetic information of the hard disk 139. So, no

The magnetic field synthesized by the magnetic field is shown in Fig. 24(C) as a magnetic field in which the direction and intensity of the magnetic field GA and the direction and intensity of the magnetic field are combined. If the timing is not shown in Fig. 24 (9), the irradiation direction of the combined magnetic field Gs can be reduced, and the irradiation magnetic field can be continuously changed by 10 ° degrees. = This, for example, when there is a hard disk for the magnetic recording medium to eliminate magnetic information ^ 'will not appear in the center of the fine rotation near the rotating scene: magnetic information that can not be eliminated, can remove the dead angle will be magnetic information:; J and 'hard disk The magnetic recording mode may be a magnetic two-flat recording along the circumference of the optical disc or a magnetic vertical type recorded in a direction orthogonal to the optical disc, by 360. Omni-directional magnetic gas illumination can virtually eliminate magnetic information. When the magnetic field directions of the first coil 211A and the second coil 211B are placed and arranged, the combined magnetic field in the multi-directional direction can be generated by the alternating current. 2 25 200809799 In the present embodiment, the first coil 211A and the second coil are used. Since the direction of the magnetic field of the coil 211B is straight, it is possible to effectively cause the direction of the combined magnetic field Gs to change 360° in all directions. Further, since the first coil 211A and the second coil 211B are supplied with alternating current having the same number of cycles, the direction of the combined magnetic field Gs can be stabilized and changed. [Embodiment 7] In the sixth embodiment, the first coil 211A of the first system and the second coil 211B of the second system are each constituted by one coil. Therefore, each of the plurality of coils of each system is used. The composition of the combination is explained. In this case, as shown in the arrangement diagram of Fig. 25(A) and the magnetic field diagram of Fig. 25(B), the configuration of each of the system coils 211A and 211B may be magnetically arranged in series. Further, the circuit configuration at this time may be electrically connected in parallel to the first system and the second system as shown in the block diagram of Fig. 26, and the coils 211 (211A, 211B) may be electrically connected in parallel in each system. The other configuration is the same as that of the sixth embodiment, and thus detailed description thereof will be omitted. In the case of such a configuration, the same effects as in the sixth embodiment can be obtained. In addition, the capacitance of the supply coil 211 power can also be reduced. In other words, when one system is constituted by one coil 211, it is necessary to supply large capacitance power to the coil 211 in order to generate a strong magnetic force. However, by arranging a plurality of small coils 211 in magnetic arrangement, as long as small capacitance power is supplied to each coil 211, the magnetic forces of the coils 211 arranged in series can be combined to obtain a strong magnetic force. 26 200809799 [Embodiment 8] The system of the first system and the second system in the sixth embodiment is constructed such that the magnetic field direction 36 进行 is performed on the secondary element plane. Rotating, as shown in the drawings (A) to (C) of Fig. 27, the third coil 211C of the third system may be provided, and the coil 211 (211A, 211B, 211C) of the three systems that irradiate the magnetic field in three directions may be provided. ). In this case, as shown in FIG. 28(A), each of the coils 211 can illuminate the individual magnetic fields GA, GB, and Gc in the x-axis, the γ-axis, and the z-axis, respectively. In this case, the electric circuit can be disposed with the coils 211A, 211B. Parallel coil 2UC. Further, in the coils 211A, 211B, in order to change the intensity of the magnetic field gs of the coils 211A, 211a, as described in the sixth embodiment, the alternating current of each phase cycle number can be periodically changed to the maximum current peak. The high peak value conversion circuit of the value. The other configuration is the same as that of the sixth embodiment, so the detailed description thereof will be omitted.

Further, in each of the above embodiments, an AC power source in which the current is continuously changed is used. However, the capacitor may be used and a DC power source may be used. In this case, the current is positive and negative, and the coil 211 is attached with a different single DC at an appropriate period. When the direct current type is used, since the capacitor and the coil 211 constitute a resonance circuit, the current of the over coil 211 is alternately converted between positive and negative, and the wave height value gradually decreases as time passes to become the attenuated alternating current. Therefore, by the magnetic field generated by the coil 211, when the magnetic pole alternates between positive and negative, the magnetic flux density gradually decreases to become an attenuating alternating magnetic field. Thus, the configuration may be such that the direct current type can be used to change the direction of the combined magnetic field synthesized by the magnetic fields generated by the respective coils 211 into various directions. Further, Embodiments 6 to 8 are used as the degaussing device 201, and the degaussing device 201 may be used as a magnetic device for attaching a voltage of one pulse to the coil 211 to generate a magnetic body.
