Abstract:
1. A read/write separated type magnetic head comprising: a read element having a magnetoresistive head having a magnetoresistive film disposed between a lower shield and an upper shield, both of which are formed on a substrate, and a pair of electrodes electrically connected to the magnetoresistive film; and a write element having a coil and a magnetic gap disposed between a lower pole and an upper pole, both of the poles are disposed on the upper shield of the read element through an insulating film; wherein the thickness of the upper shield is thinner than the thickness of the lower pole; wherein the thickness of the lower shield is thinner than the thickness of the lower pole; and wherein in the case of being arisen heat deformation of the read element and the write element at an air bearing surface side caused by changes in temperature, the amount of protrusion in the first area at the air bearing surface where disposed on the upper shield, the lower shield and the lower pole is less than the amount of protrusion in the second area at the air bearing surface where disposed on the upper pole.
