ABSTRACT:
A sled motor sliding prevention circuit prevents the sled motor from sliding during track tracing so as to enable the optical disk driving apparatus to perform high speed accessing. The inverse electromotive force occurring when the sled motor stops is removed by selectively grounding each terminal of the sled motor, so that the motor does not continue to be driven by the inverse electromotive force. Therefore, high speed access in an optical disk driving apparatus can be accomplished.
