Abstract
Hydrogen-treated, sputter deposited, titanium nodules providing enhanced micro-texturing for thin film, magnetic, disk media.
Claims2
A micro-textured, thin film, sputter deposited, magnetic media disk comprising:
- a substrate disk;
- sputter deposited, hydrogen-modified titanium sputtered from a titanium target in the presence of hydrogen to form hydrogen-treated, titanium nodules on said substrate disk;
- thin film magnetic media sputter deposited over said hydrogen-treated, titanium nodules;
- and
- a protective outer layer sputter deposited over said thin film magnetic media
- said hydrogen-treated titanium nodules defining substrate disk texturing which is transmitted through said magnetic media and protective outer layer to provide disk surface texturing;
- said hydrogen-treated titanium nodules
- containing hydrogen,
- having a height of from, 50 to 300 angstroms,
- having a diameter of from 0.5 to 3 microns, and
- having a distance between nodules of 5 to 20 microns.
