Title: Optical disk recording/reproduction device
Inventor: KIME KENJIRO
IPC: G11B11/105
Filed: 1994-12-05
Abstract: PURPOSE:To improve magnetic field strength and to stabilize recording characteristics by providing a means for screening flux of magnet leaked from a means for driving a magnetic head with electromagnetic force. CONSTITUTION:First, the distance deviation between the recording surface of an optical disk 10 and a magnetic head 16. Namely, light discharged from a light emitting element is reflected by the optical disk 10 and is applied to a two-division photodetector. Since the intensity distribution of the applied light changes depending on the above distance, the distance deviation between both can be detected by the two-division photo detector. Then, current based on the distance deviation information is applied to a coil 53 for control and the magnetic head 16 can be driven in the direction of an arrow V due to the electromagnetic force with a permanent magnet 48, thus canceling distance deviation and hence maintaining the distance between the recording surface of the optical disk 10 and the magnetic head 16 to be nearly constant.
