Acceleration sensing write disable system utilizing actuator arm coil
A hard disk drive that contains a detection circuit which senses the back emf of a voice coil. The detection circuit generates a shock detection signal when the back emf of the voice coil exceeds a pre-determined value. The write disable gate of the disk drive is disabled when the voltage detection...

| Zusammenfassung: | A hard disk drive that contains a detection circuit which senses the back emf of a voice coil. The detection circuit generates a shock detection signal when the back emf of the voice coil exceeds a pre-determined value. The write disable gate of the disk drive is disabled when the voltage detection circuit generates the shock detection signal. |
