In the field of magnetic recording, ferrite heads connected with oxide media have been in great use for a long period of time, Metal heads, for use with high Hc metal media utilizing metallic materials such as metal sendust and single-phase amorphous films have also been introduced in order to achieve high density recording. There exists a great deal of core loss in high frequency range. Ferrite heads have a related problem when applied to high density technology, that is, the low Bs of soft magnetic ferrite makes them incompatible with metal media. In order to solve those two problems, high resistive metal films possessing a very fine two phase hetero amorphous structure have been studied, magnetic granular system, where the magnetic particles are embedded in an insulator matrix has also been studied. It is necessary to improve the overall performance of the high density recording materials. |
