ABSTRACT:
A disc table employed in a disc recording/reproducing apparatus employing, as a recording medium, a recording disc, such as an optical disc or a magneto-optical disc, on which information signals are pre-recorded or are to be recorded, is disclosed. The disc table includes a fitting member fitted from its distal end into a circular center aperture of the recording disc, a table section which is integrated to the fitting member at a proximal side of the fitting member and on which a rim portion around the center aperture of the disc is set, a thrusting and supporting unit for thrusting and supporting the recording disc with respect to the table section, and a centering unit provided at a proximal side of the fitting member and adapted for thrusting the rim portion around the center aperture of the recording disc for aligning the center of rotation of the recording disc with the center of rotation of the fitting member. The fitting member is gradually tapered towards its distal end where the fitting member is provided with a guide slidingly contacted with the inner rim of the center aperture of the recording disc for guiding the recording disc towards the center of rotation of the fitting member. The recording disc may be positively centered to enable stable rotation of the recording disc while realizing a simplified thin type construction.
