MAGNETIC RECORDING MEDIUM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnetic recording medium which reduces the spacing loss and exhibits a preferable magnetic recording and reproduction characteristic.

SOLUTION: The method for manufacturing the magnetic recording medium includes: a magnetic recording layer of the granular structure having a non-magnetic grain boundary between columnar magnetic grains on a non-magnetic substrate; and an exchange coupling layer arranged on the magnetic recording layer so as to provide a function of exchange coupling between the magnetic grains. The method includes an ion applying step for applying ions to the entire surface of the exchange coupling layer after layering the exchange coupling layer on the magnetic recording layer.
