摘要

P 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. PSOLUTION: 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. PCOPYRIGHT: (C)2011 and JPO& INPIT
