More Information
Summary:Disclosed is a magnetic recording medium which enables a magnetic head to be accurately positioned even if higher-density recording of magnetic recording media is reinforced. The magnetic recording medium includes at least one servo band being magnetized in one direction and including a plurality of servo patterns being formed repeatedly along a long side of the servo band. Furthermore, each of the servo patterns includes a first magnetizing area being formed across a width of the servo band at an angle from 8 to 20 degrees with respect to the width, and a second magnetizing area being formed across the width of the servo band in non-parallel with the first magnetizing area. In addition, the first and second magnetizing areas are magnetized in a direction opposite to that of the servo band.
