Patent ID: 8108884

Claim:
An optical disk recording/reproducing device, comprising: a rotation member configured to rotate an optical disk; and an optical head configured to record information in and/or reproduce information from the optical disk, wherein the optical head includes: a light source that emits light; an objective lens that collects the light emitted from the light source on the optical disk; an objective lens actuator that drives the objective lens in a focus direction and a tracking direction of the optical disk; a movable member that is disposed in an optical path between the light source and the objective lens; a drive member that drives the movable member; and an optical base on which the light source, the objective lens actuator, the movable member, and the drive member are mounted, and wherein the drive member includes a rotor and a stator and at least a part of the stator is exposed; the drive member includes a cover member that encloses the rotor and the stator; the cover member has an opening through which at least the part of the stator is exposed; the opening includes a long hole formed along a major axis direction of the drive member; the rotation member includes a turntable of a circular shape on which the optical disk is loaded; and the long hole, when the optical head is at an innermost peripheral position with respect to the optical disk, is positioned on an inner peripheral side of the optical disk from a straight line that is tangent to an outer rim of the turntable and orthogonal to a movement direction of the optical head.
