Patent ID: 7305753

Claim:
A method for manufacturing a magnetic head comprising a first magnetic layer formed on a first magnetic layer formation surface and having a track width at a surface facing a recording medium, and a second magnetic layer having a width dimension larger than the track width, the first and second magnetic layers being disposed with a space therebetween and directly or indirectly connected together in a rear portion in a height direction, the method comprising the steps of: (a) forming the first magnetic layer on the first magnetic layer formation surface; (b) forming a first material layer-forming layer over the first magnetic layer formation surface and the first magnetic layer; (c) partially removing the first material layer-forming layer so that first material layers are disposed to cover the respective boundaries between a top of the first magnetic layer formation surface and sides of first magnetic layer, and the width dimension of each first material layer in a track width direction gradually decreases in an upward direction; (d) forming a second material layer over the first magnetic layer formation surface, the first material layers, and the first magnetic layer; (e) polishing the first and second material layers and the first magnetic layer to expose an upper surface of the first magnetic layer and form upper surfaces of the second material layer and the first magnetic layer as the same planarized surface; and (f) forming a coil layer above or below the first magnetic layer.
