The glass disc 32 has a function of suppressing vibration by a fluid force so as to correct the optical path length during recording / reproduction of the optical disk 5 and so that the optical disk 5 can rotate without surface vibration. This is because a negative pressure is generated because air flows from the inner peripheral air hole 41 to the outer periphery between the optical disk 5 and the glass disk 32 by rotation. Therefore, the optical disk 5 floats in a state of being sucked to the glass disk side and can rotate stably 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. This is because the claw 68 of the disc lifting lever 66 makes it easy to sandwich the outer peripheral portion of the optical disc 5.

The glass disc 52 has a function of suppressing vibration by a fluid force so as to correct the optical path length during recording / reproduction of the optical disk 5 and so that the optical disk 5 can be rotated without surface vibration. This is because negative pressure is generated because air flows from the inner peripheral air hole 61 to the outer periphery between the optical disk 5 and the glass disk 52 by rotation. Therefore, the optical disk 5 floats in a state of being sucked to the glass disk side and can rotate stably without surface vibration.

  The diameter of the glass disc 52 is preferably the same as the diameter of the optical disc 5, but may be smaller. This is because the claw 78 of the disc lifting lever 76 makes it easy to sandwich the outer peripheral portion of the optical disc 5. The clamp moving base 49 is configured so that the clamper 56 and the disc lifting mechanism 60 can be attached and moved up and down.

  The glass disk 32 is preferably attached to the clamp portions 31 and 51 while maintaining flatness, but it can be attached through an elastic body or attached with flexibility. Thereby, the rotation surface of the glass disk 32 is automatically adjusted by the centrifugal force caused by the rotation, and the glass disk 32 can rotate flatly.

  As shown in FIGS. 5 and 7, the disk lifting levers 66 and 76 can be lifted by the frictional force by pushing the side surface of the optical disk 5 in the center direction. Further, the claws 68 and 78 can be structured to sandwich the optical disk 5 from above and below.

Thereafter, the tray pulling mechanism 55 is moved to push the tray 1 into the cartridge 23. At this time, the cover 3 is covered on the optical disk 5.

  Next, Table 1 shows an example of a disk take-out order for continuously performing a recording / reproducing operation of the disk changer 20 using the double-sided recording / reproducing optical disk 5.

  The storage disk number indicates the storage position number from the upper side or the lower side of the optical disk stored in the cartridge 23. In this way, continuous recording and reproduction can be performed by repeating three optical disks as one unit.

  It is also possible to configure a disk changer in which a plurality of the above-mentioned A-side recording / reproducing apparatuses are arranged and a plurality of B-side recording / reproducing apparatuses are arranged above and below. In this case, continuous recording / reproducing and parallel recording / reproducing can be performed using the single-sided recording / reproducing optical disc. Further, a large-scale data recording / reproducing apparatus can be configured by arranging a plurality of the above-described disk changers vertically and horizontally and providing each disk changer with a mechanism for transporting the cartridge from the cartridge storage.

  Further, the cartridge moving table and the A-side recording / reproducing apparatus can be used alone, or the cartridge moving table and the B-side recording / reproducing apparatus can be used alone.

  An example of the above-mentioned sheet-like optical disk is one in which 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, and is a standard Blu-ray, HD-DVD. , CD, DVD, etc. can be recorded and reproduced. A sheet-like optical disk for double-sided recording / reproduction is obtained by bonding recording surfaces of two sheet-like optical disks together. The cartridge stores about 100 sheet-like optical disks per cartridge. The recording / reproducing unit can also use a commercially available recording / reproducing apparatus such as Blu-ray, HD-DVD, CD, DVD, or the like.

  In the above description, the sheet-like double-sided recording / reproducing optical disk has been described. However, recording / reproducing of a single-sided optical disk can also be performed. If the glass disk is removed, an optical disc having a standard thickness such as Blu-ray, HD-DVD, CD, or DVD can be handled.

  As described above, according to the present invention, an optical disk is supplied from a cartridge containing a plurality of double-sided recording / reproducing optical disks placed in a tray to the A-side recording / reproducing apparatus and B-side recording / reproducing apparatus, and the optical disk is temporarily retracted in the recording / reproducing apparatus. Recording / reproduction was performed after the tray was returned to the cartridge. As a result, the optical disk accommodated in one cartridge can be alternately supplied to the A-side recording / reproducing apparatus and the B-side recording / reproducing apparatus, and the recording / reproducing can be performed continuously. In addition, there is an effect that the transfer rate can be improved by operating the A-side recording / reproducing apparatus and the B-side recording / reproducing apparatus in parallel using an optical disk stored in one cartridge.

  14 and 15 show another embodiment of the A-side recording / reproducing apparatus 70 using a thin sheet-like optical disc compatible with Blu-ray. 14 and 15 have the same configuration as that of FIGS. 8 and 5 except that the floating spacer 38 and the floating stable disk 32 provided with the air hole 41 on the inner periphery are attached to the clamper 36. It is.

  16 and 17 show another embodiment of the B-side recording / reproducing apparatus 80 using a thin sheet-like optical disc compatible with Blu-ray. FIGS. 16 and 17 have the same configuration as that of FIGS. 11 and 7 except that the floating spacer 58 and the floating stable disk 52 provided with the air holes 61 on the inner periphery are attached to the clamper 56. It is.

  Also, a mechanism for moving the B-side recording / reproducing unit 45 up and down can be provided. In this case, after moving the clamp part 51 above the base 47, the optical disk 5 is inserted into the clamp part 51 and fixed by the clamper 56. Thereby, since it is not necessary to provide a large through-hole for passing the optical disk 5 in the base 47, there is an effect that even when the disk lifting mechanism 60 drops the optical disk 5, it can be received by the base 47.

  Since the recording layer of the standard 1.2 mm Blu-ray optical disc is approximately 0.1 mm from the surface, the Blu-ray compatible optical disc of the present invention having a thickness of 0.1 mm is commercially available. When recording / reproducing with a ray-compatible recording / reproducing apparatus, it is not necessary to correct the optical path length. The levitation stable disks 32 and 52 here are necessary only as levitation stability disks for rotating the optical disk 5 without surface vibration. Therefore, any material can be used as the material for the levitation stabilizing disk, such as glass, resin, metal, ceramic, etc., as long as it is lightweight and can rotate without surface vibration. The diameter of the levitation stable disk is preferably the same as the diameter of the optical disk 5, but may be smaller.

  The floating stable disks 32 and 52 and the clampers 36 and 56 are preferably integrally formed in order to ensure flatness. However, the floating stable disks 32 and 52 and the clampers 36 and 56 are flexibly provided with backlash so that they can be bonded to each other or moved with respect to each other. Can also be installed. Thereby, the levitation stable disk has an effect that the rotation surface is automatically adjusted by the centrifugal force due to the rotation and can be rotated flat.

  As described above, according to the present invention, an optical disc is supplied to the A-side recording / reproducing apparatus and the B-side recording / reproducing apparatus from a cartridge containing a plurality of double-sided recording / reproducing optical discs in which a thin sheet-like optical disc compatible with Blu-ray is placed in a tray. The optical disk is temporarily retracted in the recording / reproducing apparatus, and the recording / reproducing is performed after the tray is returned to the cartridge. As a result, the optical disk accommodated in one cartridge can be alternately supplied to the A-side recording / reproducing apparatus and the B-side recording / reproducing apparatus, and the recording / reproducing can be performed continuously. In addition, there is an effect that the transfer rate can be improved by operating the A-side recording / reproducing apparatus and the B-side recording / reproducing apparatus in parallel using an optical disk stored in one cartridge.

  Next, another embodiment of the disk changer 20 that is supplied to the A-side recording / reproducing apparatus 70 and the B-side recording / reproducing apparatus 80 with the optical disk 5 standing will be described with reference to FIGS.

  FIG. 18 shows a configuration in which the disc changer 20 that performs recording and reproduction with the optical disc 5 standing is viewed from above. 18 shows a configuration in which the disk changer 20 shown in FIG. 1 is tilted 90 degrees sideways, the cartridge moving table 24 and the clamp moving tables 29 and 49 are moved horizontally, the structure of the tray 1 and the optical disk 5 are accommodated.

The base material 2 of the tray 1 and the optical disk 5 drawn from the cartridge are moved along the U-shaped rail 82. Then, the side plates 84 and 83 of the rail 82 can be moved. The base 27 is provided with a through hole 85 through which the clamper 36 can pass. Further, the claws 88 of the disc lifting lever 66 are formed in a bifurcated structure so as to sandwich the outer peripheral portion of the optical disc 5. The hook mechanism 89 can move in the vertical direction on the paper surface.

FIG. 21 is a diagram illustrating an operation of stacking the optical disk 5 and the base material 2 in a cartridge.
In this manner, the tray insertion guide 92 provided in the hook mechanism 89 is pushed into the cartridge 23 with the outer periphery of the central portion of the optical disk 5 and the substrate 2 interposed therebetween. Then, when the optical disk 5 is stored in the cartridge 23, the hook mechanism 89 is moved to the position of the hook hooking hole 8, and the base member 2 is pushed to be pushed into the cartridge 23.

  FIG. 22 is a diagram showing the configuration of the hook mechanism 89.

  The hook moving mechanism 89 includes a hook lever 91 provided with a hooking claw 94 to be inserted into the hook hooking hole 8 of the tray 1, a fan-shaped guide 96 for guiding the hook hooking hole 8 to the hooking claw 94, and the tray. The tray insertion guide 92 provided with the introduction passage 97, the hook stop plate 101 for stopping the movement of the hook hooking claw 94, the rotating shaft 93 of the hook lever 91 provided in the tray insertion guide 92, and the hook lever 91 are provided. A ferromagnetic body 100, a spring 99 for lifting the hook lever 91, an electromagnet 106 wound around a yoke 107 for attracting the hook lever 91, a tray insertion guide 92, and a base 90 to which the electromagnet 106 is attached. The

  When the tray 1 is pulled out from the cartridge 23, the electromagnet 106 is energized, the hook lever 91 is attracted, and the hooking claw 94 is lifted up. Next, the hook hooking hole 8 of the tray 1 is introduced into the tray introduction passage 97 from the fan-shaped guide 96. Then, the energization of the electromagnet 106 is stopped, and the hooking claw 94 is moved downward and inserted into the hook hooking hole 8. When the optical disk is stored, the base 2 and the optical disk 5 are inserted into the tray introduction passage 97 with the hooking claws 94 lowered.

  As described above, according to the present invention, since the tray insertion guide is provided in the hook mechanism, there is an effect that the tray can be reliably hooked by the fan-shaped guide even when the positions of the hook mechanism and the tray are shifted. In addition, there is an effect that the optical disc and the tray are pushed into the cartridge with the tray insertion guide interposed therebetween.

The recording / reproducing operation of the A-side recording / reproducing apparatus 70 in FIG. 18 is substantially the same as the recording / reproducing operation of the A-side recording / reproducing apparatus 70 shown in FIG.

In the following description, the base material 2 of the tray 1 and the optical disk 5 drawn from the cartridge 23 are moved along a U-shaped rail 82 provided on the base 27. Then, the four disc lifting levers 66 are moved so that the outer periphery of the optical disc 5 is sandwiched between the two claws 88.
Next, the side plates 84 and 83 of the rail 82 are retracted in the direction of the arrow. Next, the base material 2 of the tray 1 is returned to the cartridge 23. Next, the optical disk 5 is separated from the substrate 2, moved to the clamp unit 30, fixed by the clamper 36, and recording / reproduction is performed. When the optical disc 5 is stored, the disc lifting levers 66 are moved at four locations so that the outer periphery of the optical disc 5 is sandwiched between the two claws 88.
