Disc drive apparatus.

摘要

A disc drive apparatus (1) employs a locking mechanism (8-11) for locking a movable base structural component (5) to a stationary frame (7) during disc loading and unloading operation. The locking mechanism is associated with a head drive mechanism (15, 16) which drives a head including a head for transferring information between a disc and the head, toward and away from the disc, so that the locking mechanism is operated between the locking position in which the movable base frame is restricted from movement relative to the stationary frame, and unloading position in which the movable base frame is permitted to move relative to the stationary frame.
