An optical pickup used to record information on and/or reproduce information from an optical recording medium, the optical pickup including an optical module to emit a light beam; and a front photo-detector to monitor power of the light beam; wherein the optical module is coupled to the front photo-detector so that a fixed distance is maintained between the optical module and the front photo-detector.

Optical pickup

A lens position determination apparatus of an optical pickup includes a lens holder with a mounted lens, a base supporting the lens holder, and a pressing member. The base has an accommodation surface accommodating the lens holder and a pair of facing support walls on the accommodation surface. The pressing member is a bendable arm. A first elastic portion between arm end portions applies an elastic force in a direction in which the arm end portions closely contact the support walls. A second elastic portion connected to the arm presses the lens holder toward the accommodation surface to fix the lens holder position. The lens adjustment can be performed while the pressing force to fix the lens holder to the base is removed by bending the pressing member into a V shape to reduce frictional resistance of the lens holder with the base during the adjustment.

A disk player includes contact members accommodating and supporting a disk at a predetermined position in a main body of the disk player. The contact members are in contact with the outer peripheral surface of the disk and the contact members are transferred to load the disk supported thereto into a clamping position, which is advantageous to miniaturizing the disk player and protecting the disk.

A damper for an optical disk drive connected between a frame and a base on which a turntable is rotatably installed, for damping vibrations transmitted to the turntable. The damper has a vertical absorption space for absorbing vertical vibration, a horizontal absorption space for absorbing horizontal vibration, and a plurality of protrusions for connecting the damper to the frame and the base. The damper is connected by inserting the protrusions of the damper into connection openings of the frame and the base.
