Description

  The present invention relates to a disk tray transport apparatus and transport method in a cartridge that accommodates a plurality of thin information recording media, and more particularly, to a transport apparatus and a transport system having a mechanism for reliably performing the operation of pulling out and storing a disk tray. It is about the method.

  In recent years, the information society has advanced and the recording density of external storage devices for storing a large amount of information has been greatly improved. In order to meet the demand for higher density in the field of optical discs, multilayer recording is possible by reducing the light spot size by shortening the wavelength of the laser and increasing the numerical aperture of the objective lens, and by increasing the transmittance of the recording layer. There are many studies on how to make it. However, at present, the method for increasing the capacity by miniaturizing the light spot diameter and increasing the number of recording layers is close to the physical limit.

  Recently, in order to increase the storage capacity of an optical disc, research on methods for increasing the volume recording density by multilayer recording or hologram recording has been actively conducted. However, in multilayer recording, light is absorbed to some extent in each layer, so a configuration of several layers is considered realistic. In holograms, it is difficult to improve the recording density by narrowing the spot. With these technologies, terabytes (TB) ) Realization of a large-capacity optical disk of the class is extremely difficult.

On the other hand, studies have been conducted to increase the volume recording density by reducing the thickness of the information recording medium. In general, research and development of a recording / reproducing technique using a thin disk made of a thin substrate having a thickness of about 0.1 mm is widely performed. In addition, a technology for accommodating the thin disc in a plurality of cartridges, a technology for taking out the thin disc from the cartridge, and performing recording and reproduction have been developed. Patent Documents 1 and 2 disclose disk cartridges that contain a large number of pairs of a thin disk and a thin disk tray (thickness of about several hundred μm) that holds the thin disk.
Japanese Unexamined Patent Publication No. 2000-57678 (FIGS. 4, 5, etc.) Japanese Patent Application No. 2005-194066, etc. (FIGS. 3, 11 etc.)

  When performing recording / reproduction of each thin disk in a disk cartridge containing a thin disk and a thin disk tray as shown in Patent Document 2, the thin disk tray holding the thin disk to be recorded / reproduced is pulled out and Access thin discs. As a method of pulling out the thin disk tray, as shown in FIG. 4, a desired thin hole is formed by using a pull-out jig having a protrusion for fitting into the hole formed in the end of the thin disk tray. An example is to pull out the disc tray. Further, after the recording / reproduction is finished, the thin disc and the thin disc tray can be accommodated in the cartridge by pressing the end of the drawn thin disc tray toward the cartridge. Although not shown, the drawer jig shown in FIG. 4 may also have a member for pressing.

  Here, since the thin disk tray is a flexible member (made of PET or the like) having a thickness of about several hundred μm, when the thin disk tray is pulled out from the cartridge by the above-mentioned pulling jig, it is shown in FIG. As described above, there is a problem that the fitting with the drawing jig is disengaged and the drawing cannot be pulled out to a predetermined position. On the other hand, it is possible to change the depth and shape of the protrusion of the drawer jig so that the mating with the thin disk tray does not come off, but if you do so, the position of the drawer hole of the stacked thin disk tray Thus, a new problem arises that the drawer jig cannot be inserted until it becomes difficult to remove the fitting from the thin disc tray. 4 and 5, the thin disk is not shown for the sake of simplification, but if the thin disk tray is removed from the drawer jig, the position of the thin disk held on it may be displaced.
