4.Write protect detectors and latches

a.Diskette

b.Panel switch

7.1.3. Drive Mechanism

The drive motor operates on 12VDC and rotates the spindle at 300 RPM through a belt—drive system. The motor speed is controlled by a feed—back from a tachometer inside the motor. A registration hub clamp that moves in conjunction with the door closure mechanism centers and clamps the diskette onto the spindle hub.
