ABSTRACT:
The separation type optical pick-up device includes a movable optical unit and a stationary optical unit having a detection portion for detecting a discrepancy between an optical axis of a light beam emitted from an emitting portion of the stationary optical unit and an optical axis of a light beam returned from the movable optical unit, and is adapted to correct the discrepancy while driving a carriage of the movable optical unit on the basis of the detected discrepancy.
