ABSTRACT:
An optical disk device. The optical disk device includes a main guide rod, a sub guide rod, a pickup head, and a protrusion. The main guide rod and the sub guide rod are parallel. The pickup head has a clamp to grasp the sub guide rod. The protrusion is disposed on the sub guide rod and movable between a first and second position. When the protrusion is in the first position, the protrusion blocks the clamp and restricts a movement of the pickup head. When the protrusion is in the second position, the clamp is released.
