ABSTRACT:
Disclosed herein is a disk drive including a base, a spindle motor mounted on the base, a disk table fixed to a motor shaft of the spindle motor and adapted to be rotated about the axis of the motor shaft by the spindle motor, an optical pickup supported movably in the radial direction of a disk-shaped recording medium mounted on the disk table, an installation plate detachably mounted on the base, a guided portion provided on the optical pickup and adapted to be guided during movement of the optical pickup in the radial direction of the disk-shaped recording medium, and a restricted groove formed on the outer circumferential surface of the disk table so as to extend in the circumferential direction of the disk table. The installation plate is integrally formed with a restricting portion inserted in the restricted groove of the disk table for restricting movement of the disk table in the axial direction of the motor shaft, and a guiding portion engaged with the guided portion of the optical pickup for guiding the optical pickup in the radial direction of the disk-shaped recording medium. Accordingly, the structure of the disk drive can be simplified and the number of parts can be reduced.
