Abstract
A heat assisted magnetic recording (HAMR) media structure is disclosed. The HAMR media structure includes a magnetic recording layer comprising an array of magnetic grains for storing information; a heat sink layer disposed below the magnetic recording layer and having a first thermal conductivity; and an anisotropic thermal barrier layer disposed between the magnetic recording layer and the heat sink layer and having a vertical thermal conductivity and an in-plane thermal conductivity, wherein the vertical thermal conductivity is substantially higher than the in-plane thermal conductivity.
