Abstract

PURPOSE:To prevent exerting of a harmful influence upon operating characteristics by holding an optical system with a holder, providing a light reflection means for reflecting optically a light to the holder, providing also a fixed light source for emitting its light against the light reflection means and providing sensors for receiving a reflected light out of the light source. CONSTITUTION:A bobbin 1 as a movable part of an actuator is turned around a pin 2 by a magnetic coil and a magnet in the direction of an arrow (a) and also moved up and down in the direction of an arrow (b). An objective lens 3 for positional detection is constituted integrally of the bobbin 1. The light of the light source 5 fitted to a non-movable part of the actuator or a head main body is reflected by a mirror part 4, and the reflected light by the mirror part 4 is received by the bisectional photo sensors 6a and 6b fitted again to the non-movable part of the actuator or the head main body, so that the turning position of the bobbin 1, i.e., the position of the objective lens 3 in a tracking direction is obtained by an amplifier 7. By this method, the exerting of harmful influences upon the operating characteristics of the actuator will be eliminated.
