A disk drive of a perpendicular magnetic recording system uses a double-layered disk medium including a soft magnetic layer. This disk drive is configured to suppress any adverse effect on a read head element under a magnetic field of a magnetic disturbance applied in a perpendicular direction, which might be caused to occur by being accentuated by a soft magnetic layer.
