Abstract:
A thin film write head for thermally assisted magnetic recording comprising:a substrate; a magnetic yoke on the substrate, the yoke comprising first and second pole pieces, each said pole piece having a pole tip, the pole tips being spaced-apart to define a write gap; a first spacer layer located in the write gap adjacent the first pole tip; a second spacer layer located in the write gap adjacent the second pole tip; a resistive heater layer of electrically conducting material located between the first and second spacer layers in the write gap for generating heat when electrical current is applied to said resistive heater layer; first and second electrical leads connected to the resistive heater layer for providing electrical current to heat said resistive heater layer, the resistive heater layer having a higher electrical resistance than said leads; and a coil layer located within the yoke for generating a magnetic field across the pole tips.
