MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve read and write characteristic of a magnetic recording medium and a magnetic recording system. SOLUTION: The magnetic recording medium comprises a substrate, a non-magnetic granular layer formed on the substrate, and a recording layer formed on the non-magnetic granular layer. The non-magnetic granular layer are formed in such a way that non-magnetic material segregates around a columnar magnetic particle to become a CoCr based alloy in hcp crystal structure or fcc crystal structure.
