Title: Production of amorphous thin film magnetic head
Inventor: HATA KUNIO
IPC: G11B5/31
Filed: 1982-08-20
Abstract: PURPOSE:To obtain an amorphous thin film magnetic head with which the electromagnetic converting efficiency is improved, by applying the parallel rotary magnetic fields to the thin film surface within a specific temperature range after forming upper and lower amorphous magnetic thin films and increasing the permeability. CONSTITUTION:Parallel rotary magnetic fields are applied to amorphous magnetic thin films 2 and 4 at temperatures 200-300 deg.C after forming these films 2 and 4 of Co-Zr, etc. on a substrate 1 or a protecting film 6 on the upper film 4 and then processing desired gap depth (d). Thus the above-mentioned magnetic field is applied after the films 2 and 4 are formed respectively to increase the reduction of permeability when the film is formed. However the permeability is slightly reduced again by the heat generated when the film 6 and the gap are formed. Therefore the parallel rotary magnetic fields are finally applied together with heating to restore the permeability. In such a way, the electromagnetic converting efficiency is improved for a magnetic head.
