SUBSTRATE FOR MAGNETIC RECORDING MEDIUM FOR DISCRETE TRACK MEDIA OR PATTERNED MEDIA, AND MAGNETIC RECORDING MEDIUM FOR DISCRETE TRACK MEDIA OR PATTERNED MEDIA

摘要

PROBLEM TO BE SOLVED: To provide a substrate for magnetic recording medium suitable for manufacturing DT media and patterned media, which requires no complex process and enables simple manufacturing of the DT media and patterned media.

SOLUTION: The substrate for magnetic recording medium uses non-magnetic base material of discoid shape as a substrate, and wettability in a prescribed region to form a magnetic film on a substrate surface is different from wettability of other regions.
