Abstract
An apparatus includes a non-metallic interlayer between a magnetic data storage layer and a heat sink layer, wherein interface thermal resistance between the interlayer and the heat sink layer is capable of reducing heat flow between the heat sink layer and the magnetic data storage layer. The apparatus may be configured as a thin film structure arranged for data storage. The apparatus may also include thermal resistor layer positioned between the interlayer and the heat sink layer.

A data storage apparatus, comprising:
- a non-metallic interlayer between a magnetic data storage layer and a heat sink layer, wherein interface thermal resistance between the interlayer and the heat sink layer is capable of reducing heat flow between the heat sink layer and the magnetic data storage layer.
A data storage apparatus, comprising:
- a thermal resistor layer between a magnetic data storage layer and a heat sink layer;
- and
- a non-metallic interlayer between the magnetic data storage layer and the thermal resistor layer,
- wherein interface thermal resistance between the interlayer and the magnetic data storage layer is capable of reducing heat flow from the heat sink layer to the magnetic data storage layer.
A data storage system, comprising:
- a heat assisted magnetic recording head;
- and
- a heat assisted magnetic recording medium positioned adjacent the heat assisted magnetic recording head, the heat assisted magnetic recording medium comprising:
- a non-metallic interlayer between adjacent layers,
- wherein the adjacent layers include a magnetic storage layer and a heat sink layer, wherein interface thermal resistance between the interlayer and at least one of the adjacent layers is capable of reducing heat flow between the heat sink layer and the magnetic data storage layer.
