Abstract: PURPOSE:To uniformize a statical frictional force between a guide shaft and an optical system holding means by providing a pulse width modulation circuit, and moving an objective lens as applying micro oscillation by an actuator by a signal waveform whose pulse width is modulated. CONSTITUTION:In the pulse width modulation circuit 11, pulse width modulation is applied on a ramp waveform that is the output of a ramp generator 1 and a triangular wave that is the output of an oscillator 10. The circuit 11 compares the ramp waveform with the signal level of the triangular wave, and outputs a pulse width modulation output, and inputs it to the actuator 4 of an auto-focus servo system 51. And the actuator 4 moves the objective lens as applying the micro oscillation on the supporting means of the objective lens toward a focusing position along the guide shaft. At this time, the triangular wave is supplied with a frequency higher than the one to which the actuator 4 can respond completely and to apply the micro oscillation on the actuator 4. In such a way, it is possible to uniformize the statical frictional force between the guide shaft and the holding means, and to shorten a focus setting time.

Abstract: PURPOSE:To decrease the effective access time by moving a disk read/write part to an address stored in an address memory section when it is detected that the accessing is not applied again within an optional predetermined time by a timer section. CONSTITUTION:When a count of a timer section 8 reaches 0, a pickup 2 is moved to an index address stored in an address memory section 4 by a control section 9, a disk drive section 3, a pickup drive section 5 and a servo circuit 6. Then the count of the timer section 8 is stopped and the count is cleared, a designated index address is set by the control section 9 to prepare the succeeding operation. The pickup is moved onto the designated index address while no data read on the disk is applied in this way. Thus, the readout time of the index information only is reduced at the succeeding accessing.
