Abstract: A disc drive apparatus includes: an apparatus body to which a disc is inserted and from which the disc is ejected; a disc recording and reproducing unit having a disc loading unit configured to load the disc inserted into the apparatus body, a disc rotation drive mechanism configured to rotate the disc loaded onto the disc loading unit, an optical pickup configured to record and/or reproduce a data signal with respect to the disc, and a pickup feeding mechanism configured to convey the optical pickup in a radial direction of the disc; a disc conveying mechanism configured to insert the disc into the apparatus body and eject the disc from the apparatus body; and a conveyance drive mechanism provided in the apparatus body and configured to drive the disc conveying mechanism; wherein the apparatus body includes a shoulder which is reduced in thickness in the vicinity of an insertion end of the disc.

Abstract: A disk drive apparatus includes: a disk table on which a disk recording medium inserted into a disk insertion port for loading is mounted; an eject lever rotatably supported by a chassis, and having a disk holding part that holds the inserted medium; and a support lever rotatably supported by the chassis and having a disk holding part, wherein these levers are rotated between a waiting position at which the disk holding part waits for the inserted medium and a drawing position at which the medium held by the disk holding part is drawn, wherein when the eject lever and the support lever are at the waiting positions, the disk holding parts are each positioned at a position which is located more on the disk insertion port side than a centering projecting part of the disk table and is not overlapped with the insertion direction of the medium.

Abstract: Disclosed is a recording medium drive apparatus configured to drive a recording medium, including a case, a drive source used for loading/ejecting the recording medium into/from the case, a motor unit configured to hold the recording medium and rotate the recording medium held, a pickup unit configured to record a signal on the recording medium rotated by the motor unit or reproduce the recorded signal, a first slider driven by the drive source to slide a first distance in a first direction, a second slider that is cam-engaged with the pickup unit and slides in a second direction to move the pickup unit upward and downward, a moving member that is releasably engaged with the first slider, engaged with the pickup unit, and cam-engaged with the motor unit, and moves the motor unit upward and downward, and a link mechanism configured to link the first slider and the second slider.

Abstract: An optical disk apparatus is provided, in which the optical disk tray can slide smoothly in and out, and the insertion and removal of an optical disk is facilitated, and wherein inadvertent scratches are not produced on the optical disk surface, and flying pieces of optical disk damaged during rotation are completely prevented from exiting the apparatus. By dividing a protrusion for preventing a damaged optical disk from flying out of the apparatus into a first protrusion and a second protrusion, with one protrusion provided on an optical disk tray and the other on a support member, any possibility of the optical disk flying out of the apparatus can be completely prevented, even if the height of each of the first and second protrusions is lowered. Because the second protrusion is lowered, the protrusion will not catch on the optical disk tray or the optical disk, and so a smooth sliding operation of the optical disk tray can be ensured.
