摘要： A disk drive is provided for restraining deterioration of the verticality of the optical axis of an optical pickup in relation to the surface of the disk when the side of the disk to be scanned for the recording and/or reproducing action is alternated from one side to the other side, in recording and/or reproducing data signals on both sides of the disk. The disk drive (1) includes a turn table (11) on which a disk D is rotatably supported, a pickup (12) for recording and/or reproducing data signals on both sides of the disk D rotated by the turn table (11), and a disk tray (31) for transferring the disk D between a recording and reproducing position which confronts the turn table (11) and a loading and unloading position at the outside of the disk drive (1). A turning movement mechanism is provided for turning the turn table (11) and the pickup (12) at once from a first position which confronts the one side of the disk D to a second position which confronts the other side of the disk D or vice versa.

摘要： A disk device is provided with a pair of slide cam members that start movement when a disk is conveyed to a replayable position, and a pair of clamper lifters respectively having clamper support portions supporting a clamper. The clamper lifters are moved in opposite directions to each other in a horizontal direction orthogonal to a thickness direction of the disk device in conjunction with the movement of the pair of slide cam members. They are arranged so that the timings of the start of movement in the opposite directions to each other are different from each other. The clamper support portions have inclined surfaces in contact with an outer peripheral part of the clamper so as to move the clamper in the thickness direction of the disk device in accordance with the movement of the pair of clamper lifters in the opposite directions to each other.

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).
