摘要： According to one embodiment, a magnetic recording apparatus includes a magnetic recording medium for perpendicular magnetic recording system, a magnetic head including a read head to read data from the magnetic recording medium, and an actuator to actuate the magnetic head on the magnetic recording medium. The magnetic recording medium includes a first magnetic pattern recorded in a servo area by applying a magnetic field horizontally to a disk surface, and the first magnetic pattern corresponding to positioning data used for positioning the magnetic head. The magnetic recording medium further includes a second magnetic pattern recorded in the servo area by applying a magnetic field perpendicularly to the disk surface, and the second magnetic pattern corresponding to position correction data used for correcting the positioning data. The position correction data is derived from modulated original position correction data. The original position correction data is created for correcting the positioning data.
