Abstract
Official abstract text for this publication.
The embodiments disclose a data storage device including a thickness gradient heat sink layer deposited over a heat sink layer deposited over a substrate, a thickness gradient non-magnetic thermal resist layer deposited over the thickness gradient heat sink layer, and a magnetic layer deposited over the thickness gradient non-magnetic thermal resist layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A data storage disk, comprising: a radial thickness-gradient heat sink layer deposited over a heat sink layer deposited over a substrate; a radial thickness-gradient, non-magnetic thermal resist layer deposited over the thickness-gradient heat sink layer; and a magnetic layer deposited over the thermal resist layer. 2. The data storage disk of claim 1 , wherein the thermal resist layer and the thickness-gradient heat sink layer pr…
