Title: Optomagnetic reading film and its reading method
Inventor: NOMURA TATSUO
IPC: G11B11/105
Filed: 1983-12-26
Abstract: PURPOSE:To attain a reading film which responds to a signal with fidelity even if the leakage magnetic field of a magnetic recording signal is weak and is immune from the effect of a magnetic domain of adjacent tracks by arranging stray magnetic domains in a soft magnetism vertical magnetizing film to a prescribed direction of many parallel strip magnetic domains. CONSTITUTION:Parallel strip magnetic domains 2h1-2h4 having a proper magnetic domain width are formed in the soft magnetic vertical magnetizing film 2a formed on the optomagnetic read film 2, e.g., a magnetic garnet film in the same interval as recording tracks 1b1-1b3 in advance and arranged closely together to be in parallel and overlapped. The signal is read by changing the width of the parallel strip magnetic domains 2h1, 2h2 by a leakage magnetic field generated from the corresponding tracks 1b1, 1b2 on which the signal is recorded. Thus, the effect from any adjacent track is less and even if the leakage magnetic field is small, the signal is transferred with fidelity to the soft magnetic vertical magnetizing film as the magnetic domain signal regardless of the recording wavelength.
