摘要： In an optical disc drive, a degradation of traveling performance of an optical pickup under hard acceleration or hard deceleration in a random access operation or the like results in a degradation of recording/reproducing performance. Groove structure is provided between two gears of a guide feed provided in an optical pickup, and the groove forms bending structure. Thus, the engagement state between a screw gear and the gears of the guide feed is stabilized. This makes it possible to prevent tooth jumping and step-out from occurring in the gears during the traveling of the optical pickup, achieving stable traveling. In consequence, the recoding/reproducing performance of the optical disc drive can be improved.

摘要： An optical disc apparatus has the following arrangements. Specifically, the optical disc apparatus includes a lock pin and a lock arm. The lock pin is disposed on a side of an inner surface of a case of the apparatus, being tapered in a protruding direction thereof. The lock arm is disposed on a side of a tray of the apparatus. The lock arm, urged by a resilient member, includes a hook portion to be engaged with an inclined surface of the lock pin. When the tray has moved to a predetermined position within the case, the lock arm is engaged with the lock pin, so that the tray is held in position at the predetermined position. When an impact force equal to, or more than, a predetermined value is applied to the optical disc apparatus, the hook portion of the lock arm is displaced in the protruding direction of the lock pin along the inclined surface of the lock pin, thereby disengaged from the lock pin. Engagement of the tray is thereby released.

摘要： An optical disc apparatus, presenting recording quality without degradation by an extreme temperature rise in an objective-lens drive mechanism in an optical pickup, includes a mechanical chassis on which a disc rotation mechanism, an optical pickup, and a transfer mechanism are mounted, a decorative plate that is a plate-shaped member located between the disc and the optical pickup and fixed on the mechanical chassis, a disc tray for loading and removing the disc, a circuit board for operation control, and an apparatus housing containing the components. A recess is formed in an indented shape in a portion of the mechanical chassis facing an outer peripheral region of the disc recording surface. An incline is formed in a position close to an opening of the disc tray for mounting the mechanical chassis and opposite the outer peripheral region of the disc recording surface, and slopes gently down to the recess.
