    摘要： A disk drive includes a disk rotating unit, a traverse base holding the disk rotating unit, a damper member holding the traverse base, a main unit holding the traverse base through the damper member, a tray mounting a cartridge housing the disk, a driving unit that loads or ejects the tray and moves the disk in the cartridge relative to the disk rotating unit, and a traverse base holding member that is moved vertically by the driving unit relative to the main unit at the time of tray loading or tray ejection. The traverse base is held by the traverse base holding member through the damper member, and the resonance frequencies of the damper member in the radius direction of the disk as it is being loaded and in the direction of a rotation shaft are set higher than the maximum rotational frequency of the disk.

    摘要： A disc apparatus for recording or reading data to or from a disc includes a tray having a table on which the disc is placed and a shielding member that covers the tray. The shielding member has a circular opening and a plurality of arc protruding members. Each arc protruding member is provided on an inner surface of the shielding member that covers the tray as protruding towards an upper surface of the disc placed on the table of the tray. An end of each arc protruding member is situated near the opening. Each arc protruding member has a protruding end with a height ranging from 1.0 mm to 1.5 mm from the inner surface of the shielding member.

    摘要： The driving state in a loading path is controlled in accordance with a loading operation of a placing member on which a disc-like medium is placed. According to a disc loading apparatus, a placing member on which a disc-like medium is placed is loaded or ejected into or from a disc loading device by a drive unit. The disc loading apparatus comprises a position detection unit which optically detects a position of the placing member in a region of movement concerting at least a portion of the loading path, and a drive profile control unit which changes a drive profile of a drive unit based on a position detection signal from the position detection unit.
