Abstract:
1. A CPP magnetoresistive head including: a magnetoresistive film comprising: a domain control film disposed by way of an insulating film on each side of the magnetoresistive film, wherein a sense current flows through the magnetoresistive film between the upper magnetic shield layer and the lower magnetic shield layer; and a high heat conductivity layer disposed between the upper magnetic shield layer and the magnetoresistive layer or between the lower magnetic shield layer and the magnetoresistive film; and a heat dissipation layer having a high heat conductivity and a low linear expansion coefficient, the heat dissipation layer being disposed at the back in a device height direction of the magnetoresistive film and on each side of the domain control film, wherein the heat dissipation layer is disposed between the high heat conductivity layer and the upper magnetic shield layer or the lower magnetic shield layer.
