Abstract
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.
