Zusammenfassung:PROBLEM TO BE SOLVED: To prevent disappearance of data due to high frequent write-in for an adjacent data track. SOLUTION: An alternate zone is formed by setting a data track for prohibiting use on every other line for a plurality of adjacent data tracks. Data of high update frequency and data of low update frequency are recorded in the alternate zone. Since interval of the data track in which data of high update frequency are recorded and the data track in which data of low update frequency are recorded is equivalent to one cylinder, disappearance of data due to leak magnetic flux can be prevented.
