Title: Magnetic head
Inventor: NISHIYAMA NOBUMASA
IPC: G11B5/245
Filed: 1988-05-25
Abstract: PURPOSE:To prevent the influence of a pseudo gap at the time of reproduction while obtaining a strong recording magnetic field at the time of recording by providing a high magnetic permeability part near the gap of magnetic materials and forming the boundary face thereof non-parallel with the longitudinal direction of the gap and within the track width in the track width direction. CONSTITUTION:The part muh where the magnetic permeability is high is provided to the central part in the track width direction near the gap (g) of pole pieces and the other parts are formed as the part mul where the magnetic permeability is low. The boundary face aa' of the magnetic permeability is so formed as to be non-parallel with the longitudinal direction of the gap. All the magnetic material parts are thereby made into poles at the time of recording but only the part of the high magnetic permeability muh appears and the reproduction track width attains the base of a triangular shape at the time of reproducing. Further, the parts parallel with the longitudinal direction of the gap are eliminated at the boundary face and the influence of the pseudo gap is eliminated. Since the base of the trapezoidal shape is longer than the base of the triangular shape, the crosstalk noises from the adjacent tracks are decreased.

Abstract: PURPOSE: To reduce influences of crosstalk due to a relative positioning error of a magnetic head by providing a magnetic disk of an electronic computer with a non- magnetic substance film between tracks.  
     CONSTITUTION: On the magnetic disk which provides high-density recording of 25μ, for example, in track width, an α-Fe 2 O 3  film is formed of a Fe target by an reactive sputter in an atmosphere of Ar and O 2 ; and then, part 1 equivalently between tracks is masked and by a thermal reducing process in H 2 , only part 2 equivalent to track width (c) is converted into a ferromagnetic Fe 3 O 4  film. Next, it is further converted into γ-Fe 2 O 3  film by a thermal oxidation process in air. Masking part 1 is still of α-Fe 2 O 3 . In this way, the track-width-(c) part of track 2 is formed of the ferromagnetic film. Consequently, there is no need to make the track width of a reproducing head narrower than that of a recording head and positioning precision of heads can be relaxed.
