Abstract:
A magnetic recording medium includes a disk substrate and a magnetic recording layer formed on one surface or both surfaces of the disk substrate. The magnetic recording layer includes at least one pattern area forming a plurality of data tracks in which a position for magnetic recording is patterned with a magnetic body and at least one continuous area formed of a continuous magnetic body, and at least a part of a servo pattern for following the data track is recorded in the continuous area. A method of recording a servo pattern on a magnetic recording medium includes determining a center position of the data track and a start position of the continuous area and recording a servo pattern for following the data track in the continuous area with respect to center position of the data track and the start position of the continuous area. A magnetic head for recording a servo pattern on a magnetic recording medium includes a data writing head for recording data, a servo writing head for recording the servo pattern, and a reading head for reproducing the data.
