摘要： Embodiments in accordance with the present invention provide a degaussing device and a degaussing method capable of efficiently degaussing a magnetic disk, especially, a magnetic disk of the perpendicular magnetic recording system, without resorting to a magnetic field of a high intensity. Embodiments in accordance with the present invention provide a degaussing method of degaussing a magnetic disk not yet installed in a magnetic disk drive by applying an external magnetic field to the magnetic disk by a degaussing device. In accordance with one embodiment, the method includes disposing the magnetic disk in the degaussing device such that the direction of an external magnetic field is inclined at an angle to the axis of easy magnetization of the magnetic disk.
