    摘要: The present invention provides an optical disc apparatus that reduces access time while suppressing the emanation of heat from a beam expander. A microcomputer manages the operation time and pause time of a stepping motor constructed to move the movable lens of the beam expander, and in accordance with the duration of an immediately previous pause, limits the number of successive stepping-motor driving actions following the pause time, below a maximum permissible count. When the pause duration is shorter than a threshold value or when the number of successive stepping-motor driving actions reaches the maximum permissible count, the microcomputer starts next driving of the stepping motor after a required waiting time.
