GAP PULL-IN METHOD FOR NEAR-FIELD OPTICAL DISK DRIVER AND OPTICAL DISK DRIVING APPARATUS USING THE METHOD |
摘要 |
A gap pull-in method that minimizes overshoot due to a moving speed of a light focusing element and disturbance of a disk when the light focusing element is converted from an open loop state to a closed loop state during a gap pull-in of a near-field optical disk driver, and an optical disk driving apparatus using the method, the gap pull-in method including: generating an inverse actuator driving signal having a pulse duration and a pulse amplitude according to a moving speed of a light focusing element when an open loop state is changed to a closed loop state in the gap pull-in; and driving an actuator using the inverse actuator driving signal.
