Title: Magnetic head and its manufacture
Inventor: IHARA KEITA
IPC: G11B5/133
Filed: 1988-07-26
Abstract: PURPOSE:To obtain a magnetic head having an excellent electromagnetic conversion characteristic and the advantage of reducing all sorts of noise and to make the magnetic head suitable for mass production by providing a groove being in parallel with the sliding direction of the head on the sliding surface of a head core consisting of ferrite and making a metallic magnetic substance having high saturation magnetization adhere to the ferrite in the groove. CONSTITUTION:The groove 5 being in parallel with the sliding direction of the head is provided on the sliding surface of the head core 2 consisting of the ferrite and the metallic magnetic substance 3 having the high saturation magnetization is made to adhere to the ferrite 2 in the groove without going through an adhering layer. Then, a magnetic gap 1 which is exposed on the sliding surface is surrounded by the metallic magnetic substance 3 and a non-magnetic glass 4 and a track width is fixed by being regulated with the aid of the non-magnetic glass 4. Therefore, since a joining part between the metallic magnetic substance 3 and the ferrite 2 does not cross the sliding direction of the head near the magnetic gap, a counterplan that a dummy gap is provided need not be considered. Thus, the excellent recording and reproduction characteristic can be obtained and the magnetic head having the advantage of reducing all kinds of noise can be easily manufactured.
