<p>A magnetic recording disk (10) composed of a substrate (11), a magnetic layer (15), and a protective/lubricantive carbon layer (13) is etched and has oxygen embedded into the surface of the disk. This carbon/oxygen surface is extremely smooth, and wears better than prior art disks not having oxygen embedded in the surface (13). This altered layer (13) enables a magnetic disk (10) to undergo over twice the number of start/stop cycles without incurring damage from magnetic transducers used to read information from the recording than similar disks prepared without oxygen in the outer layer. A method of plasma etching is used to embed the oxygen into the surface (13).</p> |
