PATTERNED MAGNETIC RECORDING MEDIA

摘要

A patterned magnetic recording medium is provided to reduce switching field distribution of the pattern magnetic recording medium by reducing magnetic interaction between adjacent magnetic recording layers, thereby increasing recording reliability and data stability. A patterned magnetic recording medium(200) includes a plurality of magnetic recording layers arranged at regular intervals on a substrate(20). Each magnetic recording layer comprises a first ferromagnetic layer(2a), a unit of suppressing magnetic interaction between recording layers, and a second ferromagnetic layer(2b), that are successively piled, wherein the unit is a soft magnetic layer(6). A non-magnetic layer(250) is sandwiched between the first ferromagnetic layer and the soft magnetic layer, and the soft magnetic layer and the second ferromagnetic layer.
