Magnetic head.

摘要

In a magnetic head, a pair of magnetic core halves (9a, 9b) are opposed to each other with a non-magnetic material (13) such as SiO2 interposed therebetween to form a magnetic gap (12), the magnetic head having a pair of magnetic core halves (9a, 9b), interposed thin films (10) and ferromagnetic thin films (11). The magnetic core halves (9a, 9b) are formed of ferromagnetic oxide such as ferrite, and they have gap forming faces to be opposed to each other to form the magnetic gap (12). The interposed thin films (10) are formed of minute crystal grains such as SiO2 on the gap forming faces. The ferromagnetic thin films (11) formed of ferromagnetic metal material such as sendust are formed on the interposed thin films (10). The ferromagnetic thin films (11) have crystal grains grown directly from the surface of the interposed thin films (10). Preferably, the ferromagnetic thin films (11) are polycrystalline substance having crystal grains with at least one of {110} face, {200} face and {211} face as a face approximately parallel to the gap forming faces. By the existence of the interposed thin films (10), the initial layer of ferromagnetic thin films can be prevented from being turned into amorphous, which was the cause of the pseudo gap generation.
