Title: Thin-film magnetic head
Inventor: ISHI TSUTOMU
IPC: G11B5/31
Filed: 1992-11-06
Abstract: PURPOSE:To embody an ideal wide write and narrow read system by alternately laminating first layers which are soft magnetic films having uniaxial magnetic anisotropy and second layers which are nonmagnetic films to form multilayered magnetic films, thereby forming magnetic poles. CONSTITUTION:NiFe layers 2 which form the first layers and v layers 3 which form the second layers are alternately and continuously laminated by using an electron beam vacuum vapor deposition device having two units of evaporating sources. The multilayered NiFe/V films are patterned by ion milling to the shapes of the magnetic poles 1 of 3mum width of magnetic pole patterns. The thickness of the NiFe layers 2 is controlled to 50nm and the thickness of the V layers 3 to 20nm by changing the opening and closing time of shutters provided right above the respective evaporating sources. The magnitude of the anisotropic magnetic field Hk of the NiFe layers 2 of this time is 60e and the magnitude of the saturation magnetization Ms is 800gauss. The regions at 1mum both ends of the magnetic poles exists as immobile regions and a change in the magnetization does not arise when these regions are magnetized by 50Oe (10MHz) magnetic field and, therefore, the thin-film magnetic head which executes a writing operation at 3mum width 4 and a reading out operation at 1mum width 5 is obtd.
