Abstract
A permanent magnet generator incorporated in a diskette that can be inserted into a floppy disk drive is disclosed. In the permanent magnet generator, electric power is generated as a rotor is caused to rotate at a revolution twice to ten times as high as that of the drive shaft of a floppy disk drive by transmitting the rotation of the drive shaft to a rotor via a speed increasing mechanism incorporated in a diskette. Since the cogging torque of the generator is reduced, the rotor can be caused to rotate with a small drive torque. This allows the generator to produce a high output.
