MAGNETIC RECORDING MEDIUM

摘要

PURPOSE: To improve wear resistance and durability by sticking a lubricant made of a Ti compd. having benzenesulfonyl groups represented by a specified structural formula on a carbon protective film. CONSTITUTION: A lubricant made of a Ti compd. having benzenesulfonyl groups represented by the structural formula is stuck on a carbon protective film on the magnetized layer of a magnetic recording medium. The coefft. of friction is reduced by the Ti compd. and the objective magnetic recording medium having improved wear resistance and durability is obtd.
