OPTICAL PICKUP DEVICE OF OPTICAL DISK DRIVE AND OPTICAL PICKUP DRIVING METHOD

摘要

PURPOSE: An optical pickup device of an optical disk drive is provided to latch an optical head in the state of the optical head being unloaded when a shock or an external disturbance is generated, while detaching a disk cartridge, thereby preventing system damage caused by collision between the optical head and an optical disk. CONSTITUTION: An optical head(20) has a slider(23) mounted with an objective lens(21) and raised by forming an air bearing in a gap with an optical disk. The objective lens focuses an incident light. A wire suspension(30) connects the optical head with a base member(10), to freely move the optical head in the base member. A driver drives the optical head in a tracking direction and a focusing direction. An optical head latch(50) fixes a location of the optical head separated from the optical disk, to prevent collision between the optical head and the optical disk, caused by an external shock.
