Claims

[Scope of utility model registration request]

A floppy disk drive device comprising a disk rotation mechanism that rotates a magnetic disk with a jacket and a center hole while gripping the magnetic disk, and a head mechanism that freely approaches and separates from the magnetic disk and records and reproduces data, The head mechanism is connected to an air flow controlled by a chopper to bring the head mechanism into contact with and away from the magnetic head.
A floppy disk drive device comprising a damper and a solenoid, which are connected via a speed reduction mechanism.
