Abstract

PURPOSE: To enable an optical disk device to record and reproduce a signal on and from a disk while a concentric track and spiral track coexist, by controlling a transporting motor for tracks.
CONSTITUTION: For a motion picture, when a sigal is inputted to terminal S, flip-flop 33 is set to make transporting motor 9 start rotation and since the output of rotary encoder 10 is excluded by AND gate 31 during recording other than still picture recording, transporting motor 9 rotates without being controlled by rotary encoder 10, turning transporting screw 8 continuously at a constant speed. For a still picture, the output of rotary encoder 10 resets flip-flop 33 via gate 31, and consequently transporting motor 9 rotates under the control of rotary encoder 10 to move optical system unit 9 by steps, thereby recording a signal on a concentric track.
