A magnetic recording medium includes a positioning magnetic layer having magnetism and is used for positioning the optical head. The magnetic recording medium recording method includes a first step of moving the magnetic head to a predetermined position on the magnetic recording medium, a second step of supplying a positioning magnetic field Hr from the magnetic head to the positioning magnetic layer for positioning the optical head, and a third step of outputting positioning light Pr from the optical head for positioning the optical head, producing a magnetic optical effect with respect to the positioning magnetic layer magnetized by the positioning magnetic field Hr, and controlling the optical head so as to face a position of the magnetic head based on a detection result of the magnetic optical effect. |
