摘要： An optical disk device includes a head including an actuator that supports and moves an objective lens at least in a direction of focusing, and a slider for transporting the head in the direction of tracking. In response to a static acceleration acting on the objective lens in response to a change in the posture of the optical disk device, and a low-frequency component of a tracking servo signal for causing the objective lens to track, a slider controller drives the slider so that the objective lens is aligned with the center of an optical field of view of the head. In this arrangement, the slider is controlled with reference to the low-frequency component of the tracking servo signal corrected in accordance with the level of gravity acting on the objective lens. Slider control is thus achieved to prevent a displacement, between the objective lens and the center of the optical field of view, caused by a change in the posture of the optical disk device.

摘要： An optical pick-up device that records and/or reproduces information on an optical information recording medium, through the use of holography, can prevent deterioration of recording and reproduction accuracy due to vibrations from exterior or fluctuations in the relative positional relationship with the recording medium. The optical pick-up device includes a pick-up body and a position adjusting device. The position adjusting device changes the position of the pick-up body in a direction perpendicular to a surface of the recording medium, in a direction parallel to the surface of the recording medium, and in such a direction as to change the inclination of the pick-up body with respect to the surface of the recording medium.

摘要： An optical disk device comprises position control portions which carry out position control of at least one of an optical head and an objective lens based on a detection signal from the optical head, and disturbance learning portions which reduce a compensation gain of the position control portion in a range in which servo control is not deviated, and detect disturbance information of the optical disk to store it as learning disturbance information. Fine disturbance information can be reliably learned because the information is not affected by the compensation gain.

摘要： An optical disc system and a method of managing shock while recording or playing data in the optical disc system are provided. The optical disc system includes an optical pick-up unit for applying a laser beam to a track of an optical disc and detecting reflected light, a servo unit for controlling tracking and focus of the optical pick-up unit and a monitoring unit for comparing a monitoring signal, which is output from the optical pick-up unit and the servo unit, with a reference signal and generating a blocking signal and a blocking release signal. Recording or playing of data on the optical disc is stopped in response to the blocking signal, and recording or playing of the data on the optical disc is resumed in response to the blocking release signal based on a state of the optical disc system when recording or playing was stopped.
