キュームポンプとを含んで構成される。Since the conventional magnetic disk cleaning device described above does not have the function of demagnetizing the magnetic disk, it is necessary to provide a separate degaussing mechanism to clean the magnetic disk that has become contaminated by the surrounding magnetic field. The magnetic disk cleaning device of the present invention includes an arm having an air blowing hole and an air suction hole on opposing surfaces of a U-shaped tip, and an N'S hole on the U-shaped tip surface of the arm.
three magnets each arranged in such a way that their poles face each other and the adjacent poles are different; an actuator that moves the arm horizontally to the center of the magnetic disk; and a cleaner that sends clean compressed air to the air outlet. The air generating device includes an air generator, an ionizer located in a path between the air blowing hole and the clean air generating device, and a vacuum pump for sucking air from the air suction hole.
