Title: Magnetic recording medium
Inventor: NAGAO AKIRA
IPC: G11B5/73
Filed: 1986-06-17
Abstract: PURPOSE:To permit the formation of an anodized film to >=2mum thickness at which high hardness and mechanical strength are obtd. by constituting a magnetic material to be packed into the fine holes of the anodized film of a high-magnetized part on a front layer and low-magnetized part on a bottom layer side. CONSTITUTION:The coercive force of the low-magnetized part 4c on the bottom layer side is as high as 87.5-159.2KA/m and is longer in the distance from a magnetic head; therefore, the low-magnetized part 4c is substantially not magnetized any more. Since the magnetic material has a polycrystalline structure in the branch part 4b, the continuity as magnetism decreases. The low- magnetized part 4c, therefore, makes substantially no contribution to magnetic recording and only the high-magnetized part 4a having 71.6-79.6KA/m on the front layer side contributes to magnetic recording. The thickness L2 of the anodized film after surface grinding is thus the total of said thickness and the thickness of the low-magnetized part 4 even if the thickness of the high- magnetized part 4a is decreased as small as 1-1.5mum at which magnetic characteristics are assured. The anodized film of >=2mum at which the high hardness and mechanical strength are obtd. is thereby formed.
