Inventor: HORINO KOICHIRO
IPC: G11B11/105
Filed: 1992-01-27
Abstract: PURPOSE:To accurately record data by forming a magnetic path layer on the disk, arranging annular magnetic poles magnetically connected with a yoke of a magnetic circuit for driving an optical head and eliminating a leakage magnetic field which acts on a recording spot on a magnetooptical recording film. CONSTITUTION:A magnetic field generating coil 3 is provided on a magnetic head 2 above the disk 1. On the other hand, underneath the disk 1, the optical head 5 is arranged in a position corresponding to the head 2. The head 5 is composed of an objective lens 6, a polarizing beam splitter, a collimator lens and optical system parts such as a semiconductor laser, etc. Then, the lens 6 is controlled to be driven by a driving mechanism including the magnetic circuit 8 in order to focus an optical beam 4 on the magneto-optical recording film 1b. The circuit 8 possesses an exciting coil 9 and the yoke 10, and the annular magnetic poles 12 magnetically connected with the yoke 10 are arranged. By this method, a magnetic field is formed by leakage magnetic flux 20 from the coil 9 via the magnetic path layer 11, the magnetic poles 12 and the yoke 10.
