The target (designated) tray 1 is positioned at a desired position.

  On the other hand, the recording / reproducing apparatus 70 is disposed in the U-groove rail 27, a tray / disk drawer mechanism 35 for pulling out the tray 1, a U-groove rail 27 for guiding the optical disk 5 pulled out from the tray 1, and the U-groove rail 27. A disc stop plate 83 for positioning the optical disc 5 on the clamp unit 31, a recording / reproducing unit 25 for recording / reproducing the optical disc 5 disposed on one side surface of the tray / disc drawer mechanism 35, and the recording / reproducing unit. 25 is mounted on the recording / reproducing unit moving base 28 that can move in the horizontal direction (vertical direction in the figure), and the other side surface of the tray / disc drawer mechanism 35. A clamp moving table 2 provided with clampers 36 for fixing to the 25 clamp portions 31 and movable in the horizontal direction (vertical direction in the figure). It is composed of a. The recording / reproducing unit moving base 28 and the clamp moving base 29 move while being guided by a pair of guides 19.

  Next, as shown in FIG. 4, the tray / disk drawer mechanism 35 is provided in the horizontal movement mechanism 89 that can move in the direction of the cartridge 23 and the horizontal movement mechanism 89. As shown in b) and (c), the index 18 provided on the base material 2 of the tray 1 is pulled out, or the hook hole is hooked into the hook hole, and the outer periphery of the optical disc 5 is further extended. It comprises a tray / disk pinching mechanism 91 having a function of pinching and pulling out. The horizontal moving mechanism 89 includes a linear bearing 86 and a linear guide 87, and the linear bearing 86 moves while being guided by the linear guide 87. The tray / disk pinching mechanism 91 includes a movable plate 93, a guide plate 92, and a rotation center 90 of the movable plate, thereby realizing a pinching mechanism on the moving unit provided with the linear bearing 86. Move with. When the tray / disk clamping mechanism 91 sandwiches the index 18 of the tray 1 and the outer periphery of the optical disk 5, the index 18 and the optical disk 5 are inserted into a guide portion that is provided in a fan-shaped opening on the guide plate 92. Thereafter, the movable plate 93 is rotated and sandwiched between the guide plate 92 and the movable plate 93.

  The peeling claw 26 is for peeling the cover 3 of the tray 1 shown in FIGS. 2 (a), 2 (b) and 2 (c). As shown in FIG. Is pulled out by the tray / disk drawer mechanism 35, the cover 3 is pushed up by inserting a protrusion into a cover lifting hole 10 (see FIG. 2A) provided in the base 2 of the tray 1, The tip of the cover is hooked on the peeling claw 26 and peeled off.

  The recording / reproducing unit 25 is provided on the spindle motor 30 for rotating the optical disc 5, a clamp unit 31 for fixing the optical disc 5 thereon, and an elastic body on the clamp unit 31.

It is composed of

  The glass disk 32 is used to stably levitate / rotate the disc along with optical path correction for reading and writing information on the thin sheet-like optical disc 5. Therefore, as shown in FIG. 5 described above, an air hole 41 is provided on the inner peripheral side. Further, in order to create a gap between the optical disk 5 and the glass disc 32, a so-called floating spacer 38 is attached. Further, the glass disk 32 has a function of suppressing vibration by a fluid force so that the optical disk 5 can be rotated without surface vibration. Specifically, a negative pressure is generated between the optical disk 5 and the glass disk 32 due to the rotation because air flows from the air hole 41 on the inner peripheral side toward the outer periphery. Therefore, since the optical disk 5 floats in a state of being sucked toward the glass disk side, it can be stably rotated without surface vibration. The diameter of the glass disc 32 is preferably the same as the diameter of the optical disc 5, but may be smaller.

  Next, as shown in FIG. 5 described above, the clamper 36 causes the ferromagnetic material 42 (iron piece or the like) embedded in the clamper 36 to be magnetized by the permanent magnet 39 embedded in the opposing clamp portion 31. The optical disk 5 is pressed against and fixed to the clamp portion 31 with the suction force. On the contrary, the same effect can be obtained by providing the permanent magnet 39 on the clamper 36 side and providing the ferromagnetic body 42 on the clamp portion 31.

  Further, as shown in FIG. 1 described above, the clamp moving base 29 has a clamper 36 attached to a part thereof, and is configured to be movable in the horizontal direction (vertical direction in the figure). As shown in FIG. 5, the clamper 36 is held on the clamp moving base 29 by a holder 44 for holding the clamper 36 freely.

  In addition, in order to ensure the flatness, the glass disk 32 and the clamp part 31 mentioned above are adhered via an elastic body between them, or provided with a gap so that they can move with each other, and are attached flexibly. You can also. Thereby, the rotation surface of the glass disk 32 is automatically adjusted by the centrifugal force caused by the rotation, and thus, there is an effect that the glass disk 32 can be rotated while being held flat.

  1 further includes a housing 21 of the disk changer 20, and an insertion port 22 provided in a part (side surface) of the housing 21 for inserting the cartridge 23 therein. , The guide 19 of the cartridge moving table 24 is shown. The cartridge moving table is powered by a driving source (not shown), like the moving unit of the tray / disk drawer mechanism and the optical unit moving mechanism, It is configured to be movable.

  Next, the recording / reproducing operation of the disk changer 20 will be described. As shown in FIG. 1 above, first, the cartridge moving table 24 is moved, so that the designated tray 1 is transferred from the trays stored in the cartridge 23 to the tray disk of the recording / reproducing apparatus 70. Position at the position of the drawer mechanism 35.

  Next, as shown in FIG. 4, the tray / disk drawing mechanism 35 is moved, and the index 18 c of the tray 1 in the cartridge 23 is clamped by the tray / disk clamping mechanism 91. Subsequently, the tray 1 is pulled out to a position where the optical disk 5 accommodated in the tray 1 can be sandwiched. At this time, the cover 3 is peeled from the tray 1 by the peeling claw 26. Next, the tray / disk pulling mechanism 35 is moved, the outer peripheral portion of the optical disk 5 is pinched by the tray / disk pinching mechanism 91, and the tray 1 is pulled out from the tray 1 in this state. Then, the optical disk 5 is guided into the U-groove rail 27 and moved to a position in contact with the disk stop plate 83 (that is, a recording / reproducing position). Then, the optical disk 5 is released from the tray / disk clamping mechanism 91.

  Next, the clamp moving base 29 is moved, and the clamper 36 is stopped in the vicinity of the optical disk 5 disposed in the U-groove rail 27 as shown in FIG. Thereafter, the recording / reproducing unit moving base 28 is moved, and the clamp unit 31 of the recording / reproducing unit 25 is inserted into the clamp hole 6 of the optical disc 5. Further, the recording / reproducing unit moving base 28 is moved, the clamper 36 and the clamp unit 31 are fitted, and the optical disc 5 is fixed to the clamp unit 31. Thereafter, the recording / reproducing unit moving table 28 is moved, that is, the recording / reproducing operation is performed in a state where the clamper 36 can move freely without contacting the holder 44.

  Next, an operation for returning the optical disk 5 from the recording / reproducing unit 25 into the cartridge 23 will be described. This is an operation of returning from the state shown in FIG. 5 to the state shown in FIG. 1 through the state shown in FIG.

  First, in the state shown in FIG. 5, the recording / reproducing unit moving base 28 is moved, and the clamper 36 is removed from the clamp unit 31. Further, by moving the recording / reproducing unit moving base 28, the optical disk 5 comes into contact with the side surface 82 of the U-groove rail 27 and stops in the groove, while the clamp unit 31 is detached from the optical disk 5. As a result, the optical disk 5 is returned into the U-groove rail 27.

  Next, the recording / reproducing unit moving table 28 and the clamp moving table 29 are moved to a position where they do not come into contact with the tray / disk drawer mechanism 35. Then, as shown in FIG. 4, the tray / disk drawer mechanism 35 is moved to the left, the optical disk 5 is pushed into the tray 1, and the optical disk 5 is further moved to return the tray 1 to the cartridge 23. At this time, the cover 3 is covered on the optical disk 5.

  In the above description, the optical disc 5 is transported to the recording / reproducing apparatus 70 in a standing state together with a plurality of trays 1 in which a plurality of trays 1 in which thin optical discs 5 are housed are housed. However, the present invention is not limited to this example. For example, the above-described disk changer is stored in the tray 1 in which the thin sheet-shaped optical disk 5 is stored. It can also be applied to a recording / reproducing apparatus using a cartridge (that is, stacked and housed). In this case, when pulling out the optical disc 5 from the tray 1, the tray holding mechanism built in the cartridge 23 applies a pressing force from the direction perpendicular to the adhesive portion 4 of the tray 1 so that the tray 1 is not pulled out by the frictional force. It may be possible to give and hold.

  It is also possible to configure a disk changer in which a plurality of the above recording / reproducing apparatuses are arranged in parallel so that an optical disk can be supplied from a single cartridge to a plurality of recording / reproducing apparatuses. Alternatively, a plurality of the disk changers are provided side by side in the vertical and horizontal directions, and a mechanism for transporting the cartridge from the cartridge storage is provided for each disk changer, thereby constituting a large-scale data recording / reproducing apparatus. Is also possible.

  In addition, as an example of the sheet-like optical disc 5, a recording layer is provided on the surface of a base material such as polycarbonate resin or polyester resin having a thickness of about 0.05 mm to 0.2 mm. Can be recorded / reproduced in the standard format of DVD-HD, DVD, CD, for example. The cartridge can store, for example, about 100 sheet-like optical disks per cartridge.

  In addition, a recording layer in an optical disc such as a DVD-HD, DVD, or CD having a standard thickness of 1.2 mm is usually present at a position approximately 0.6 mm from the surface. On the other hand, in the optical disk 5 of the present invention, the recording layer is provided on the surface of a substrate having a thickness of 0.1 mm, and therefore the optical path correction is performed with the above-described glass disk having a thickness of 0.5 mm. If it does, a recording layer will exist in the position of 0.6 mm, Therefore For the recording / reproducing part, it is possible to use the recording / reproducing apparatus which can be easily obtained also in a general market. The non-recording area at the outer peripheral portion is about 1 mm.

  As described above, according to the present invention, it is possible to supply the optical disc to the recording / reproducing apparatus from a cartridge in which a plurality of thin sheet-like optical discs are stored in the tray and to record / reproduce the optical disc. Play.

  In addition, as described above, the optical disk 5 can be taken out from the cartridge, and recorded / reproduced and stored again in the cartridge by simply reciprocating the tray / disk drawer mechanism 35. In particular, the access time can be shortened. Exhibits excellent effects.

  Conventionally, when the tray 1 is pushed into the cartridge 23, the base material 2 is pushed, so that it is necessary to increase the plate thickness so that the base material 2 does not buckle. On the other hand, in the present invention, since the mechanism for pushing the tray 1 into the cartridge through the optical disk 5 is employed, the base material 2 does not buckle. Therefore, it is possible to make the base material 2 of the tray 1 thin, and there is an effect that the number of trays (optical disks) stored per cartridge can be increased. Further, since the weight per cartridge can be further reduced, it is possible to expect an effect that the cartridge can be moved at a higher speed.

  In the above-described embodiment, since the tray 1 and the optical disk 5 accommodated in the cartridge are in a standing position, they do not receive a load from the adjacent tray 1, so that the sliding between the optical disk 5 and the tray 1 There is an effect that adverse effects such as scratches on the optical disk 5 can be eliminated. In addition, it is possible to reduce the force when the tray 1 and the optical disk 5 are pulled out or stored from the cartridge, that is, the pulling-out force and the pushing-in force. Furthermore, the effect that it is possible to prevent wear powder from being generated by sliding between the tray 1 and the cartridge can be expected. In addition, by arranging a plurality of recording / reproducing apparatuses in parallel, an optical disk can be supplied from a single cartridge to a plurality of recording / reproducing apparatuses, and the use efficiency of the entire apparatus can be improved. Can also be obtained.

  Next, an optical disc recording / reproducing apparatus including the disc changer 20 compatible with Blu-ray (standard) will be described with reference to FIG. The configuration shown in FIG. 6 is the same as that shown in FIG. 1 except that the glass disk 32 provided with the air holes 41 on the inner peripheral side and the spacer 38 are attached to the clamper 36. The configuration of the disc changer 20 is the same. In the case of Blu-ray (standard), information is recorded / reproduced by irradiating light from the optical unit 33 constituting the recording / reproducing unit from the substrate side of the optical disk 5 having a thickness of 0.1 mm. Therefore, the glass disk 32 does not need to pass light, and can be formed using a material such as metal, ceramic, or resin, for example. Hereinafter, this glass disk is referred to as a “floating stable disk” 32. The levitation stable disk 32 and the clamper 36 are desirably formed integrally, however, they can be attached via an elastic body or can be attached with a gap therebetween. As a result, the levitation stable disk 32 can be stably rotated without being shaken by centrifugal force. The recording / reproducing operation is the same as that of the changer shown in FIG.

  The recording layer in an optical disc compatible with Blu-ray having a standard thickness of 1.2 mm is located at a position of approximately 0.1 mm from the surface. Therefore, in the optical disc 5 used in the optical disc recording / reproducing apparatus of the present invention, the recording layer is provided on the surface of the base material having a thickness of 0.1 mm, and therefore, the Blu-ray method that is easily available in the general market. The recording / reproducing apparatus can be used as the recording / reproducing unit.

  As described above, according to the present invention, a thin sheet-like optical disc compatible with Blu-ray is placed in a tray, and this is stored in a plurality of cartridges. In addition to the effect that a thin sheet-like optical disk can be recorded / reproduced at high speed, the same effect as that obtained by the disk changer 20 of FIG. 1 can be exhibited.
