Abstracts__ The excellent corrosion resistatice is the fundamental requirement for the practical magnetic media. The corrosion behavior of sputtered C/CoNiCr/Cr thin film in Sooc. SO'YoRH environment were investigated in terms of AES, SIHS atid VSH. The results show that the cobalt signal is clearly detected on the carbon surface after only 1.5 hours ex-posure. The diameter of cobalt rich particales spreaded on the carbon surface is in the rat~ of 150 to 250 A. TIlese particles grow up atid
more » ... r the whole sample surface with the increase of testil~ time. when the Co oxide film become thicker, the magnetization strength of recording media is reduced. This corrosion process is electrcichemical type. key words: Nagnetic recordil~ media. Corrosion resistatice. AES. SINS.
