发明名称 Magnetic recording medium
摘要 Disclosed is a magnetic recording medium which has a high S/N ratio of an output read from a servo signal, few deposits adhered to a head, and a low error ratio. The magnetic recording medium has a magnetic layer which includes a servo band onto which a servo signal for controlling tracking of a magnetic head is written and a data band onto which data are recorded. The servo signal is written onto the servo band which has been magnetized in one direction along length of the magnetic recording medium, by magnetizing the servo band in a direction opposite to the one direction. Further, the magnetic layer has indentation hardness of 60 to 140 Kg/mm<2>.
