Abstract
There is provided a magnetic storage medium capable of recording information at high recording density and also to regenerating the information with a high quality of signal (high S/Nm), and in addition contributing to the elongation of a life span of the recorded information. The magnetic storage medium comprises a non-magnetic substrate and a magnetic recording layer provided on the substrate. The magnetic recording layer has a ferromagnetic grain consisting of a ferromagnetic material and an antiferromagnetic matrix consisting of an antiferromagnetic material.
