MAGNETIC RECORDING MEDIUM, SERVO SIGNAL RECORDING APPARATUS AND METHOD OF PRODUCING MAGNETIC RECORDING MEDIUM |
| 摘要 |
There is provided a magnetic recording medium including a magnetic layer. The magnetic layer has a servo signal recorded thereon by magnetizing a part of the magnetic layer in a first direction. The first direction contains a component of a perpendicular direction that is perpendicular to a top surface of the magnetic layer. The magnetic layer is pre-magnetized in a second direction before recording of the servo signal. The second direction contains the component of the perpendicular direction. The second direction is opposite to the first direction. |
