ABSTRACT:
A disk drive apparatus has a main apparatus, a disk tray, a disk rotational drive unit, an optical pickup mechanism, a movable member, an elevator drive mechanism, a protrusion provided on the movable member, and a vibration-absorbing member provided on the protrusion. The disk tray causes a disk to move between a stored position and a drawn-up position relative to the main apparatus. The movable member supports the disk rotational drive unit and the optical pickup mechanism and is mounted to the frame of the main apparatus so that one end is free to rotate. The elevator drive mechanism causes the disk rotational drive unit and optical pickup mechanism to approach and move away from the disk, with the movable member free to move up and down. The protrusion extends toward one end of the movable member. The movable member is provided with the vibration-absorbing member.
