Abstract
A substrate having a carbon-deuterium protective overcoat layer, and method for making the same. In some embodiments, the substrate includes a recording structure having a magnetic recording layer. A protective overcoat layer is Formed on the recording structure, the protective overcoat layer composed of carbon-carbon (C—C) and carbon-deuterium (C-D) bonds and having no carbon-hydrogen (C—H) bonds.

An apparatus, comprising:
- a base substrate;
- a recording structure in contact with the base substrate comprising a magnetic recording layer;
- and
- a protective overcoat layer in contact with the recording structure, the protective overcoat layer composed of carbon-carbon (C—C) and carbon-deuterium (C-D) bonds and having no carbon-hydrogen (C—H) bonds, the protective overcoat layer comprising C2D4 and having a bond strength of at least about 110 kcal/mole.
An apparatus comprising a protective overcoat layer supported by a magnetic recording layer, the protective overcoat layer composed of carbon-carbon (C—C) and carbon-deuterium (C-D) bonds with no carbon-hydrogen (C—H) bonds, the protective overcoat layer comprising C2D4 and having a bond strength of at least about 110 kcal/mole.
