Claims

[Scope of utility model registration request]

A disk rotation mechanism including a drive hub and a cone that can freely move toward and away from the magnetic disk that grips and rotates the magnetic disk with a jacket and has a central hole; and a disk rotation mechanism that can move toward and away from the magnetic disk to record and reproduce data. a head mechanism, and a disk set switch that detects when a magnetic disk inserted into the floppy disk drive exceeds its normal position and returns to its normal position by an eject mechanism, and detects the disk set switch. In a floppy disk drive device equipped with a cone load drive source that moves the cone toward the drive knob based on a signal to grip and set the magnetic disk, the cone load drive source moves the cone toward the drive knob in response to a detection signal from the disk set switch. A floppy disk drive device comprising a control circuit for releasing a load drive source.
