Patent ID: 7545603

Claim:
A magnetic head comprising: a first magnetic layer and a second magnetic layer facing each other with a predetermined gap in a film width direction, each magnetic layer having a facing surface; a coil layer formed between the first magnetic layer and the second magnetic layer; and a front surface of the first magnetic layer formed with a substantially constant predetermined width in a first direction on the facing surface, wherein the first magnetic layer has a front portion and an inclined portion, side surfaces of which extend in directions crossing the first direction, each side surface forms a different angle with respect to the facing surface, and an absolute value of an angle formed between the side surface of the front portion and the facing surface is larger than an absolute value of an angle formed between the side surface of the inclined portion and the facing surface, wherein the first direction is a track width direction, wherein a second direction is orthogonal to the facing surface, and a length of a trailing upper surface of the front portion in the second direction is larger than a length of a leading lower surface of the front portion in the second direction.
