Abstract
PURPOSE: To improve durability by providing a coating a specific fatty acid on a magnetic metal thin film for a magnetic recording medium containing Co.
CONSTITUTION: To a mangetic metal thin film containing Co, a saturated fatty acid of more than C12 such as a stearic acid is bonded in the proportion of 50W 500mg/m2. Thus, the lubricity is improved and the durability will not lower much even after long-period use.
