Magnetic recording medium, magnetic recording apparatus and magnetic recording method

摘要

A magnetic recording medium capable of alleviating thermal fluctuation and improving the recording density includes a functional layer ( 12 ) containing a magnetic material, and a recording layer ( 11 ) overlying the functional layer and containing a magnetic material. The recording layer contains a plurality of magnetic grains ( 51 ) and a nonmagnetic material ( 52 ) existing among the magnetic grains, and the functional layer and the recording layer exert exchange coupling interaction in a direction making a substantially orthogonal relation with each other at the room temperature.
