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 sensor for detecting insertion of the magnetic disk into the proper position in the floppy disk drive device; and based on a detection signal from the sensor, the core is moved toward the drive hub to remove the magnetic disk. In a floppy disk drive device equipped with a cone-load drive source for gripping and setting a magnetic disk, the floppy disk drive device includes a light-emitting element and a light-receiving element arranged opposite each other, and generates an index signal based on a detection hole formed in the magnetic disk. An index sensor is provided to detect the insertion direction of the magnetic disk, and an index signal from the index sensor is valid under a cone load ON signal generation condition for the cone load drive source to determine the gripping state of the magnetic disk. A floppy disk drive device comprising a control circuit that generates a ready set signal to maintain the floppy disk drive.
