Abstract

본 발명은 광픽업 구동 방법에 관한 것이다.The present invention relates to an optical pickup driving method.

본 발명은 광픽업의 적어도 일부를 원하는 위치로 이동시키기 위한 광픽업 구동 방법에 있어서, 상기 광픽업의 적어도 일부를 캐리지에 대하여 자기적으로 부상지지하는 복수의 자기현가장치를 이용하여 그 광픽업의 적어도 일부를 그 이동시킬 방향과 반대 방향에 있는 일극 현가장치의 극에 위치시키는 단계와, 상기 광픽업의 적어도 일부가 그 복수의 자기현가장치와 함께 탑재되는 캐리지를 갖는 보이스 코일 모털를제어하여 그 캐리지를 소망하는 위치로 이동시키는 단계와, 상기 캐리지가 소망하는 위치에 도달하면, 상기 복수의 자기현가장치를 제어하여 상기 광픽업의 적어도 일부에 대한 포커싱 및 트랙킹 제어를 행하는 단계를 포함하고 있다.The present invention provides a method of driving an optical pickup for moving at least a portion of an optical pickup to a desired position, wherein the optical pickup is formed by using a plurality of magnetic suspension devices that magnetically float at least a portion of the optical pickup with respect to the carriage. Positioning at least a portion of the pole of the pole suspension in a direction opposite to the direction of movement thereof, and controlling the voice coil hair having a carriage in which at least a portion of the optical pickup is mounted with the plurality of magnetic suspensions; Moving the carriage to a desired position, and when the carriage reaches a desired position, controlling the plurality of self-suspension devices to perform focusing and tracking control on at least a portion of the optical pickup.

이와 같은 본 발명의 광픽업 구동 방법은, 이동중의 광픽업에 가해지는 강성을 제거하므로 광픽업은 거의 진동하지 않게 된다. 따라서, 데이타의 판독 및 기록에 대한 신뢰도는 한층 증진되고, 종래와 같이 픽업의 진동이 진정될 때까지 기다리지 않아도 되므로 그만큼 탐색시간을 줄일 수 있다.Since the optical pickup driving method of the present invention removes the rigidity applied to the optical pickup during movement, the optical pickup hardly vibrates. Therefore, the reliability of reading and writing of data is further enhanced, and the searching time can be reduced accordingly because it is not necessary to wait until the vibration of the pickup is calm as in the prior art.

Claims

An optical pickup driving method for moving at least a portion of an optical pickup to a desired position, the optical pickup driving method comprising: a plurality of magnetic suspension devices that magnetically float at least a portion of the optical pickup relative to a carriage; Positioning the poles of one side suspension in a direction opposite to the direction of movement, and controlling a voice coil motor having a carriage on which at least a portion of the optical pickup is mounted together with the plurality of magnetic suspensions, so that the carriage is desired. Moving to a position of the optical pickup; and when the carriage arrives at a desired position, controlling the plurality of self-suspension devices to perform focusing and tracking control on at least a portion of the optical pickup, thereby vibrating during movement of the optical pickup. Optical pickup driving method characterized in that to suppress the.

The optical pickup driving method according to claim 1, wherein the focusing and tracking control step is performed by controlling at least four magnetic suspension devices disposed at front, rear, left, and right sides of at least a part of the optical pickup.

※ Note: It is to be disclosed based on the initial application.
