This paper summarizes work carried out on thin-films of CoCr deposited on glass surfaces. The use of negative biasing during RF sputtering is reported, especially as it affects impurity gas contamination and the promotion of good microstructure. To reduce contamination from the glass, a gold or titanium underlay er is used. The effect of titanium is extensively studied. Magnetic domain measurements show that the CoCr/Ti/glass system is suitable for high-density perpendicular recording.
