Title: Vertically magnetized recording medium
Inventor: ICHIYAMA YOSHIKAZU
IPC: G11B5/02
Filed: 1983-12-19
Abstract: PURPOSE:To reduce the level of the medium noise and also to increase the track density by applying the initial magnetization to each of adjacent tracks in polarities opposite to each other and vertically to the film surface and having clear positions and boundaries of tracks. CONSTITUTION:A vertically magnetized recording medium 10 is made of a cobalt-chrome alloy which is coated on a substrate 11 or polyester or aluminum, etc. by a sputtering process, etc. together with a recording layer 12 having a magnetization facilitating axis vertically to the film surface. Then the medium 10 is initially magnetized for each track vertically to the film surface and in opposite directions to each other by a magnetic head having the same width as the track pitch. The magnetization 14 is reversed every one of adjacent tracks and therefore extremely stable since a state approximate to A closed magnetic path is obtaind quite easily through a leakage magnetic flux 15. Thus the magnetization is performed evenly along tracks. This produces no stray magnetic domain with reduction of levels of medium noises. In addition, the direction of the magnetic flux leaking out vertically to the film surface is different every track. This ensures a clear boundary between adjacent tracks.
