Optical recording/reproducing apparatus and method for using various sizes and types of recording/reproducing mediums therein

摘要

An optical recording and/reproducing apparatus is capable of using a selected one of various types of recording/reproducing mediums including disc cartridges (200, 210) of at least two different sizes, a naked disc, and an adapter containing a disc having a diameter of 8cm, by positioning the selected recording/reproducing mediums on one tray (20). The apparatus includes a tray (20) mounted to a case (10) and receivable into and withdrawable from the case (10). The tray (20) accommodates the selected recording/reproducing medium so as to prevent movement of the recording/reproducing medium relative to the tray (20). A detecting section detects the size of the selected recording/reproducing medium positioned on the tray (20), and a state of a disc accommodated therein. A rotating section rotates the disc. An information recording/reproducing section records information onto, and/or reproduces information from, the disc rotated by the rotating section. <IMAGE>
