Abstract:
A magnetic head comprising:an inductive head for recording including a lower magnetic core, a write gap film formed on the lower magnetic core an upper magnetic core having a track portion and a portion spreading from the track portion, a plurality of insulating films laminated between the lower magnetic core and the upper magnetic core, and a coil formed between the plurality of insulating films, one of the plurality of insulating films determining a zero throat level position and the track portion of the upper magnetic core being an air bearing surface; and a magnetoresistance effect head for reproducing including a lower shielding film and a magnetoresistance effect sensor film formed between the lower shielding film and the lower magnetic core, wherein the position where the upper magnetic core spreads is located nearer to the air bearing surface than the tip end position arranged nearest to the air bearing surface among the tip end positions of the insulating films formed on the insulating film determining the zero throat level position.
