PURPOSE:To increase the recording density through the avoidance of the effect of negative edge, by mounting the chip tilt to the slider and wrapping the chip until the taper of the upper magnetic substance layer is exposed, in the thin film magnetic head for magnetic disc. CONSTITUTION:The lower magnetic layer 12 is formed on the substrate 11, the conductor part 13 surrounded with the insulation layer is formed on the layer 12, and the upper magnetic layer 14 is mounted on the insulation layer, and one end is connected to the layer 12 and another end constitutes the gap with the layer 12 through the insulation layer, and the thin film magnetic head chip is fitted tilt with the slider 5 do that the taper 14a of the magnetic substance layer 14 and the floating surface are parallel, and polishment is made until the taper 14a is exposed. Thus, the taking the taper angle as 45 deg., for example, the thickness of pole P2' is about six times the recording wave length, and if the substrate 11 is taken as a magnetic substance, the pole thickness P1' is freely adjusted with the size at chip cut-off. Thus, the effect of negative edge can be avoided by taking thick thickness than the pole thicknesses P1, P2 not fitted tilt. |
