Abstract

PURPOSE: To reduce the weight of a device by emitting a light beam for detecting a position from an optical head, and detecting the light beam by means of a position detecting means provided fixedly and separately from optical head, and performing the position detection of the optical head.
CONSTITUTION: The position of the optical head 2 is detected by projecting a laser beam L from the optical head 2 to an optical scale sensor (position detecting means) 36, which is different from the optical head 2 and arranged at a fixed base 102. Accordingly, the optical head 2 need not to be equipped with the scale sensor 36 in itself. Thus, the device can be miniaturized and lightened, and further, an access time can shortened by the reduction of the weight. Besides, the optical scale sensor is not limited to only this type. and for instance, a CCD line sensor (charge transfer element) can be used.
