Abstract: PURPOSE:To exactly track individual beams onto the center line of tracks by changing the deflecting direction of the light of mirrors arranged in correspondence to a semiconductor laser, making the exit direction of the individual beams of the multibeams respectively independently controllable. CONSTITUTION:The plural laser beams from the semiconductor laser are reflected by a multimirror deflector 102. This multimirror deflector 102 is arranged with the moving mirrors 302a, 302b and 302c, 302d at prescribed intervals symmetrically with a stationary mirror Part 306 as a center line on a substrate 305. These mirrors are rotated around a suspension 301 by applying a voltage to electrodes 303. Then, the tracking error signals detected independently by the respective mirrors from the reflection spots of the laser beams are fed back to the servo system of the respective mirrors, by which the respective individual mirrors are controlled and driven in desired directions and the respective spots are exactly tracked to the tracks on the disk.
