Magnetic recording medium, magnetic recording apparatus using the same, and method and apparatus for manufacturing the magnetic recording medium

A magnetic recording apparatus comprising:

• a magnetic recording medium;
• a single pole type (SPT) head;
• a slider on which the SPT head is mounted;
• a suspension arm for securely fastening the slider;
• and
• an actuator for supporting the suspension arm, wherein
• the SPT head can be transported to an arbitrary position on the recording medium by the movement of the actuator where it can record information, and wherein
• the magnetic recording medium comprises at least a soft magnetic underlayer and a recording layer, wherein
• the angle formed by the direction of easy magnetization of the recording layer and the direction normal to the medium is not less than 5° and not more than 55°, and wherein, when the easy magnetization direction is from a back surface of the recording layer toward a front surface thereof and when the direction of recording tracks is from the upstream of the direction of transportation of the medium toward the downstream thereof, the direction of a projection of the easy magnetization direction on the medium plane substantially coincides with the recording track direction.
