Corrosion resistance of CoCrPtTa thin film media under high temperature and
humidity environment (60 degrees C, 80 RH) was investigated. Effects of sp
uttering parameters, such as film thickness, Ar pressure, substrate bias, p
rotective layer thickness and composition were studied. It is shown that Cr
underlayer thickness and Ar pressure play important roles in the suppressi
on of Co corrosion. (C) 2000 Elsevier Science B.V. All rights reserved.
