ABSTRACT:
A magnetic recording medium includes recording regions formed on a substrate, isolation regions formed between the recording regions so as to define the recording regions, and recording dots formed of a dot-like magnetic recording layer and arrayed in the recording regions, the recording dots including first recording dots arrayed in a line in each edge part of each recording region along the isolation region and second recording dots arrayed into a regular lattice in a central part of each recording region. A distance between a first recording dot and a second recording dot which are nearest neighboring is larger than a distance between second recording dots which are nearest neighboring.
