ABSTRACT:
A magnetic recording device includes a composite magnetic head, which includes a recording head and a reproduction head, and a magnetic recording medium. The magnetic recording medium includes a data region for recording data using the recording head, a mask pattern region in which an area in which servo information can be magnetically recorded and an area in which information cannot be magnetically recorded are formed in a predetermined pattern, and an initial positioning region in which a magnetic area and a nonmagnetic area that record information for positioning one of the recording head and the reproduction head in the mask pattern region.
