Abstract

Diamond is disclosed as a coating for recording disks. Polycrystalline diamond is chemically vapor deposited on a substrate followed by a partial removal of the substrate material, exposing selected areas of the underside of the diamond film. This is accomplished by suitable mounting and etching procedures. The selected surfaces of diamond are coated with suitable recording media. The regions of substrate previously removed are backfilled to re-establish the structural integrity of the disk, producing a recording media with the chemical and mechanical protection of diamond, see Figure 1.

Diamond Coated Disk by Backside Processing

      Diamond is disclosed as a coating for recording disks.
Polycrystalline diamond is chemically vapor deposited on a substrate
followed by a partial removal of the substrate material, exposing
selected areas of the underside of the diamond film.  This is
accomplished by suitable mounting and etching procedures.  The
selected surfaces of diamond are coated with suitable recording
media.  The regions of substrate previously removed are backfilled to
re-establish the structural integrity of the disk, producing a
recording media with the chemical and mechanical protection of
diamond, see Figure 1.
