SLED JAMMING CONTROL METHOD OF OPTICAL PICK-UP

摘要

Sled jamming preventing method of the optical pickup device, where prevent the sled jamming between the optical pickup and the read screw according to apply the three kinds of the voltage level. The voltage levels are as follows: the first level in order to transmitting the optical pickup to the high speed from the controller, the second level in order to backwarding the optical pickup according to back-rotating the sled motor, and the third level in order to forward moving the optical pickup to the low speed.
