Abstract

PURPOSE:To miniaturize a device by incorporating an electromagnetic thrust driver driving axially and electromagnetic circuit driver driving in a rotational direction in a body with a shaft equipped with an optical head at its one terminal. CONSTITUTION:Shaft 43 is equipped with coils 18 and 42, and condenser lens 35 is fitted to shaft 43 via support plate 44 so that its optical axis will be parallel to an axis ecdentric from the center axis of shaft 43. Shaft 43 is partially supported by slide bearing 40 being slidable and rotatable. In this constitution, supplying a focus position control current to coil 18 moves shaft 43 as shown by arrow A to correct a focus position. Further, supplying a track tracking position control current to coil 42 turns shaft 43 as shown by arrow B, moving condenser lens 35 in the direction perpendicular to the track. Thus, focus position control and track tracking control are exercised by a device driving one shaft, so that the device will be miniaturized.
