Patent ID: 6914750

Claim:
A method for fabricating a magnetic read/write head and slider assembly having improved heat spreading and heat dissipation characteristics and reduced thermal protrusion comprising: providing a read/write head and slider assembly wherein the write element portion of said read/write head comprises at least a lower magnetic pole piece, an, upper pole tip and yoke assembly and an inductive coil positioned between said pole piece and yoke; forming a heat sink layer over the upper surface of the yoke, said layer being in thermal contact with the yoke and said layer being formed as a double layer, comprising a first layer which is an electrically insulating spacer layer and a second layer selected from the group of electrically conducting and magnetic materials having thermal conductivities higher than those of surrounding and contiguous materials and wherein the electrically insulating layer is in contact with the upper surface of the yoke; forming an insulating overcoat over the assembly.
