ABSTRACT:
An optical storage device having a lens opposite to a storage medium comprises an actuator that moves the lens,a mechanical shock acceleration sensing means that senses a mechanical shock acceleration, a collision prevention control means that drives the actuator for a predetermined period of time with a first driving force greater than the maximum rating force of the actuator when the mechanical shock acceleration sensed by the mechanical shock acceleration sensing means becomes a value equal to a predetermined value, and then, that drives the actuator with a second driving force smaller than the maximum rating force of the actuator.
