    摘要： The invention allows for restriction of radial and axial movements of a shaft by a simple structure. A shaft supporting structure includes a base (3) provided with a bearing (7), and a first shaft (23) arranged at the bearing (7). The shaft supporting structure further includes a helical torsion spring (4) fitted on the first shaft (23). The base (3) includes a first engagement hole (31a), and a hooked section (74) engaging with first and second arm sections (41, 42) of the helical torsion spring (4), respectively. The helical torsion spring (4) presses the first shaft (23) onto the bearing (7) in a radial direction of the shaft by an elastic force generated by engagement between the first arm section (41) and the first engagement hole (31a) of the base (3), and engagement between the second arm section (42) and the hooked section (74) of the base (3). A portion of the second arm section (42) faces an axial end face of the first shaft (23).

    摘要： A disk drive comprises a cartridge holding mechanism which has a small size and reduces a damper load. The disk drive comprises: a spindle motor 91 which mounts and rotates a disk; a traverse base 82 which holds the spindle motor 91; a rubber damper 71 which flexibly holds the traverse base 82; a mechanical chassis 60 which holds the traverse base 82 through the rubber damper 71; a tray 20 which mounts a cartridge 1 in which a disk is housed; and a loading motor 61 which moves the disk in the cartridge 1 close to the spindle motor 91 or away from the spindle motor 91. The cartridge 1 is supported by the mechanical chassis 60 through the tray 20.

    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.
