Optical disk device

Abstract

In one embodiment, an optical disk device includes a tray in which any of recording mediums with differing outer diameters such as a cartridge housing a disk and a bare disk can be selectively mounted, the device being configured such that by transporting the tray into the main body of the optical disk device, the recording medium mounted in the tray is made to be chucked by a turntable. In the optical disk device, holding means that hold the recording medium at a predetermined position of a mounting face of the tray are provided in a front portion and a rear portion respectively in the transport direction of the tray, at least one of the holding means is configured so that a holding member can move to a first holding position where it is possible to hold a small diameter recording medium, and to a second holding position where it is possible to hold a large diameter recording medium, and the holding member is biased to the first holding position by a biasing means.
