Hardware Description

In August 1995 NEC announced the DSE1340A and DSE2010A ATA 3.5-inch magnetic disk units and the DSE1340S and DSE2010S SCSI 3.5-inch magnetic disk units. All four models featured the industry’s highest storage capacity of 670 MB per disk. To increase the units’ storage capacity, NEC used PRML, a demodulation method that raises the head density and read efficiency.
