Abstract
An optical recording and/reproducing apparatus is capable of using a selected one of various types of recording/reproducing mediums including disc cartridges of at least two different sizes, a naked disc, and an adapter containing a disc having a diameter of 8 cm, by positioning the selected recording/reproducing mediums on one tray. The apparatus includes a tray mounted to the case and receivable into and withdrawable from the case. The tray accommodates the selected recording/reproducing medium so as to prevent movement of the recording/reproducing medium relative to the tray. A detecting section detects the size of the selected recording/reproducing medium positioned on the tray, 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.
