A logic signaling system that enables data communication between a
supported host and the library. HVD signaling uses a paired plus and
minus signal level to reduce the effects of noise on the SCSI bus. Any noise
that is injected into the signal is present in both a plus and minus state,
and is canceled. Synonymous with differential.
