Abstract

PURPOSE: To reduce the vibration and noise and to increase the reliability, by screw feed of the arm at normal feed, by feeding the arm with the linear motor at high speed feed and by the constitution that the arm and the feed screw are not directly coupled.
CONSTITUTION: In picking up the color video signal modulated from the video disc 5, drive current is fed to the plunger 31 to gear the half nut 25 and the feed screw 19, and the arm 1 is moved from outer to inner circumference. Further, in fast feeding or fast returning the arm 1, the power application to the plunger 31 is stopped and the drive current is fed to the drive coil 33 and the arm 1 is moved with the linear motor in high speed. Thus, vibration and noise can be prevented with the high speed movement of the arm 1 by the linear motor, and assembling is made easy by gearing the feed screw 19 and the half nut 25 to increase the reliability.
