Latest Patents
Brent D Hermsmeier holds a patent for a magnetic recording medium featuring a CoPtCrB alloy thin film. This high-density longitudinal recording medium comprises a CoPtCrB alloy with a chromium content exceeding 17 atomic percent. The invention exhibits high coercivity, low noise, and elevated Curie temperatures. The films are prepared by sputter depositing a chromium or chromium alloy underlayer on a non-magnetic substrate. A strong [100] crystallographic orientation of the underlayer is essential for achieving a low noise, high coercivity medium. This orientation is accomplished by depositing the underlayer on a negatively biased substrate under high temperature and low pressure conditions. The oriented underlayer prevents the subsequently deposited CoPtCrB alloy from orienting itself in its preferred c-axis vertical orientation. The CoPtCrB alloy consists of 4 to 12 percent platinum, 18 to 23 percent chromium, and 2 to 10 percent boron.
