| abstract | PURPOSE: To facilitate low input operations to make recording high-density, by providing high-permeability materials such as permalloy and pure iron between the magnetic layer and the ground layer by the ion plating method. n CONSTITUTION: High-permeability materials such as permalloy and pure iron are provided between the ground material, which constitutes a drum, a disc, a wire, and so on, and the magnetic layer by the ion plating method. Then, most of the magnetic force line which is generated from the head core and passes through the magnetic layer passes in the high-permeability layer, and consequently, the magnetic force line is centralized to make high-density recording possible. In the magnetic recording material having the composite magnetic layer including this high-permeability layer, low input operations are facilitated because the magnetic flux in the unit volume is increased. n COPYRIGHT: (C)1981,JPO&Japio |
