Abstract
An apparatus includes a magnetic layer, a heat sink layer, and a thermal resistor layer between the magnetic layer and the heat sink layer. The apparatus may be configured as a thin film structure arranged for data storage. The apparatus may also include an interlayer positioned between the magnetic layer and the thermal resistor layer.
Claims19
An apparatus, comprising:
- a magnetic layer;
- a heat sink layer;
- and
- a thermal resistor layer between the magnetic layer and the heat sink layer, wherein the thermal resistor layer is structured and arranged to allow heat flow from the magnetic layer to the heat sink layer and structured and arranged to reduce heat flow from the heat sink layer to the magnetic layer.
