Abstract

PURPOSE:To make the device small-size, light-weight, and cheap, by mounting one light control optical system on positioners and joining and separating the head positioner and the recording positioner to switch the recording mode and the reproducing mode. CONSTITUTION:In the reproducing mode, a head positioner 3 is moved in directions of arrows A and B selectively in a high speed intermittently through a guide 4 by a motor to move a light control optical system 1 to the object position. In the recording mode, a steel ball 2 is joined with a feed rod 5 to join a recording positioner 6 and the head positioner 3 under the state where a constant current is flowed to a driving motor for the head positioner 3 to give a constant acceleration. The light control optical system 1 is then moved to the object position by a high-precision feeding of a screw feeding mechanism 7. Thus, the device is small-size, light weight, and cheap.
