Objective lens drive device and disk drive equipped with the objective lens drive device

摘要

A disk device includes a base that has a support shaft (23) and magnets (25); a movable unit (18) that is supported on the support shaft rotatably about the support shaft and slidably along the support shaft, holds an objective lens, and has a focusing coil (38) and a tracking coil (39), and magnetic members (41,42) that are formed in linear shape and are attached to the movable unit, and hold the movable unit in a neutral position in a focusing direction and in a tracking direction by attraction of the magnet members to the magnets. The device is used for receiving a disk recording medium for recording or playback by transmitting laser light through an objective lens held by the movable unit. <IMAGE>
