A lead line connected to electrodes of the MR head is connected to MR element terminals 20 via a copper stud. An outgoing line from coils of the write head is connected to write element terminals via a copper stud. The stacked body of the MR head and the read head, the lead line, and the coil outgoing line are covered with an alumina protection film. The MR element terminals and the write element terminals are formed on the alumina protection film. Each of the MR element terminals and the write element terminals has a slit and is sectioned in a height direction of the slider by the slit.

摘要： A thin film magnetic head which can suppress magnetic saturation at opposite ends of width of a narrow track width to reduce the amount of recording side-fringing onto a recording medium and which can assure a necessary recording magnetic field satisfactorily. Also a magnetic disk apparatus using the head. A second magnetic yoke has a magnetic gap depth over which the spacing of a magnetic gap keeps substantially equal toward a rear portion of the second magnetic yoke, starting at the tip of a second magnetic pole and the spacing between a first magnetic yoke and the second magnetic yoke is increased toward the rear portion, starting at a position corresponding to the magnetic gap depth. The second magnetic pole of the second magnetic yoke has in the track width direction a width for recording a signal on a track width of the recording medium. The width keeps constant over a predetermined length toward the rear portion, starting at the second magnetic pole tip and spreads monotonically toward the rear, starting at a position corresponding to the predetermined length. The predetermined length terminating in the spread start position of the width of the second magnetic yoke is set to be shorter than the magnetic gap depth.

摘要： According to embodiments of the present invention, a magnetic head slider provided with a heater disposed near a read element to adjust flying height, is required to increase a thermal protrusion by heat generated by the heater without increasing a thermal protrusion attributable to heat generated by a recording current or environmental temperature. A magnetic head slider includes a thin-film head unit including a read element, a heater having a thin heating line extended above and below the read element, a write element, and an insulating layer of alumina (Al2O3) or the like insulating those components. The thin heating line of the heater is formed from a thin resistive film of NiCr or the like. The thin heating line of the heater is extended above and below the read element so as to meander in a zigzag shape in a direction perpendicular to the device forming surface. The thin heating line has a thickness between about 0.1 and 0.2 μm, a width between about 1 and 3 μm, a length of about 100 μm, and a resistance between about 50 and 500 Ω.
