摘要： A pickup control method and a recording medium recording/reproducing apparatus are provided to prevent posture instability of a pick-up unit by delaying driving pulse for a specific time after the second driving pulse. A pickup control method is as follows. A driving pulse having a first cycle is applied to drive a pick-up unit moving in a first direction. The cycle of the driving pulse is changed to a second cycle at the point of time when the pick-up unit turns from the first direction to a second direction. The driving pulse is returned to the first cycle after the pick-up unit has turned to the second direction. The second cycle is longer than the first cycle, and different from the natural frequency of the pick-up unit.
摘要翻译：提供拾取控制方法和记录介质记录/再现装置，以通过在第二驱动脉冲之后的特定时间延迟驱动脉冲来防止拾取单元的姿势不稳定。拾取控制方法如下。施加具有第一周期的驱动脉冲来驱动沿第一方向移动的拾取单元。在拾取单元从第一方向转换到第二方向的时刻，驱动脉冲的周期变为第二周期。在拾取单元转到第二方向之后，驱动脉冲返回到第一周期。第二个循环比第一个循环长，并且与拾取单元的固有频率不同。

摘要： There is provided a servo system for controlling position of a sensor assembly (30) in a data readout and/or writing device (10). The device (10) includes: (a) two actuators (28, 36) for spatially actuating a structural assembly (22) and its associated sensor assembly (30), the system further comprising: (b) a servo control unit (34) in communication with the two actuators (28, 36) for controlling spatial movement of the structural assembly (22) and the sensor assembly (30). The controlling means (34) is operable: (c) to apply substantially velocity feedback control to the actuators (28, 36) when the sensor assembly (30) is substantially remote from a desired target position; and (d) to apply substantially position feedback control to the actuators (28, 36) when the sensor assembly (30)is substantially spatially proximate to said target position. The servo control unit (34) further includes pole-compensating filtering means for at least partially compensating response poles of the structural assembly (22) and its sensor assembly (30) so as to result during operation of the system in smoother switching between said substantially velocity feedback control and said position feedback control for enhancing at least one of temporal and spatially responses of the system when controlled by the servo control units (34).

摘要： An apparatus for recording and/or reproducing a disk-shaped optical recording medium such as a magneto-optical disk includes a recording and/or reproducing unit, a moving unit and a controller. The recording and/or reproducing unit records input information on the disk-shaped optical recording medium loaded on the apparatus and reads out information recorded on the optical recording medium. The moving unit moves the recording and/or reproducing unit in the radius direction of the disk-shaped optical recording medium. The controller controls a recording and/or reproducing operation of the recording and/or reproducing unit and an operation of the moving unit. The controller controls the moving unit such that a moving speed for moving the recording and/or reproducing unit by the moving unit when the recording and/or reproducing unit records input information on the disk-shaped optical recording medium is lowered as compared with a moving speed for moving the recording and/or reproducing unit by the moving unit when the recording and/or reproducing unit reproduces the disk-shaped optical recording medium.
