SURFACE MODIFICATION METHOD AND MAGNETIC RECORDING MEDIUM WHOSE SURFACE IS MODIFIED BY THE SURFACE MODIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium capable of stably performing loading/unloading of a magnetic head without providing a loading/unloading zone on an outer peripheral part. SOLUTION: The surface modification method is characterized in that a surface pressure higher than that of an inner peripheral part is applied to an outer peripheral part of the magnetic recording medium on which a lubricant is applied to increase a bond film thickness of the outer peripheral part. The magnetic recording medium whose surface is modified by the surface modification method is also provided. COPYRIGHT: (C)2011,JPO&INPIT
