摘要： A disc table employed in 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 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 with the center 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.

摘要： A mold for forming an optical disk base provided with a movable specular plate, a stationary specular plate, and an annular stamper having inner and outer peripheral edges. The reverse surface of the stamper is in contact with one of the specular plates, and the stamper is supported at its inner end portion by an inner stamper retainer and at its outer end portion by an outer stamper retainer. A cavity is formed between the stamper and the other one of the specular plates when the mold is closed. This mold further has: a circumference ring having an extreme end surface located inside the outer stamper retainer in the radial direction and facing a surface of the stamper, and an inner peripheral surface defining an outer peripheral surface of the cavity, the circumference ring being supported on the other specular plate so as to be movable in the mold opening/closing direction; and an actuator for moving the circumference ring between a position at which the extreme end surface abuts against the stamper and a position at which the extreme end surface is flush with the specular surface of the other specular plate or is recessed from this surface away from the cavity.

摘要： An injection molding die apparatus for use in the production of an optical disk substrate has a stationary die part having a mirror-finished surface, a movable die part carrying a stamper, an outer peripheral ring slidably fitting on the outer periphery of the movable die part and contactable with the stationary die part when the movable die part has been moved close to the stationary die part, such that a die cavity to be charged with injected molten plastic is formed by the mirror surface of the stationary die part, the stamper and the outer peripheral ring. First and second ejection mechanisms are provided to push the injection-molded optical disk substrate away from the stamper simultaneously both at the central portion and outer peripheral portion of the optical disk substrate, while the optical disk substrate is held in close contact with the mirror-finished surface of the stationary die part, whereby the separation of the injection-molded optical disk substrate from the stamper takes place uniformly without distortion and failure in the transfer of the track grooves.
