MAGNETIC RECORDING MEDIUM, METHOD FOR MANUFACTURING THE SAME, AND STORAGE DEVICE

摘要

<P>PROBLEM TO BE SOLVED: To suppress the effect of thermal fluctuation by suppressing local volume reduction of magnetic particles forming a recording layer when the recording layer is patterned in a magnetic recording medium, the method for manufacturing the same and a storage device. Ž<P>SOLUTION: The magnetic recording medium includes the recording layer having a granular structure wherein the magnetic particles are dispersed in a non-magnetic mother body and a non-magnetic material embedded in a recessed part of a pattern formed in the recording layer. The magnetic particles are so constituted as to have a reverse truncated cone shape where a diameter in an upper region of the recording layer is larger than a diameter in a lower region of the recording layer.
