摘要： An optical disk device capable of securing a rigidity of a tray that holds an optical disk is provided. When an optical disk is put into trays stacked in a main body, a holding portion provided to the tray holds the optical disk. In this case, since the holding portion holds the optical disk from the label face side of the optical disk, a recording face located on the opposite side to the label face can be opened without provision of a notch in the tray. Accordingly, a rigidity of the tray can be secured.

摘要： When storage of an optical disc in which information has been recorded is started, a pair of rollers rotate while holding the optical disc inserted through an insertion/ejection slot of a body of an optical disc device, so that the rollers convey the optical disc to the inside of the body. On this occasion, circumferential edge sensing units provided in the inside of the body sense a circumferential edge of the inserted optical disc continuously to thereby sense the outer diameter, shape and insertion state of the inserted optical disc. The optical disc is ejected when decision is made that there is abnormality.

摘要： An optical disk device has superior vibration characteristics by preventing vibration of a rotating arm. A desired optical disk is selected from the plurality of optical disks which are stacked and accommodated. The rotating arm is rotated to a working space provided for the desired optical disk. A turntable is positioned, and an optical head is moved to perform the recording/reproduction. Because the tip part of the rotating arm of a cantilever structure is supported by a support member extending along the axial line CL of the optical disk, it has a structure supported by both ends. Thus, the vibration of the rotating arm can be prevented. Because the support member extends along the axial line CL of the optical disk, it passes through a holding hole at the center of the optical disk and a notch provided at the center of a tray, without interference on its way, thereby supporting the rotating arm.

摘要： There is provided an optical disk device that is capable of obtaining a required optical disk holding force uniformly and sufficiently. When information held and recorded on an optical disk is reproduced, a recording face of the optical disk is loaded on a loading portion of a clamping mechanism, then a projection portion is passed through a hollow portion of the optical disk to the label face side, and then the optical disk is held by chuck claws protruded from the projection portion. At this time, the chuck claws are turned around a supporting shaft provided along a tangential direction of the projection portion respectively to clamp the optical disk, but base end portions of the chuck claws are pushed by pushing portions provided to pushing members to have an elasticity and are turned. Therefore, even when a particular chuck claw gets caught, the pushing portions that are pushing the caught chuck claws are elastically deformed to allow the pushing members to move, so that remaining pushing portions push the base end portions of remaining chuck claws.
