IPC: G11B5/73
Filed: 1986-12-12
Abstract: PURPOSE:To reduce the magnetic connecting force of a magnetic medium film and to reduce the noise level for a magnetic recording medium, by giving a microscopic grain structure to a magnetic recording film and segregating a composition component different from the center part of the crystal grain of the magnetic recording film to the grain field of the grain to form a deteriorating layer to the grain field for magnetic connection between grains. CONSTITUTION:A magnetic film has a microscopic grain structure and an element which gives segregation to the grain boundary of a grain to reduce the magnetic coupling force between grains into the magnetic film as a 2nd or 3rd additional element. In other words, a composition component different from the center part of a crystal grain is segregated to the grain boundary for the magnetic film having a grain structure. Thus a nonmagnetic layer is formed in the grain boundary. As a result, the magnetic coupling force is reduced among grains and the noise level of the magnetic film is reduced without having the large zigzag inversion of magnetization that is recorded by a magnetic head for recording information.
