A line of high-capacity, half-height 5.25 Winchester disk drives using thin-film head technology has been introduced by the CAST unit of Century Data Inc, Anaheim, California: the 14000 Series drives come in formatted capacities of 114Mb, 140Mb, and 170Mb; all can be used with high-speed ESDI or SCSI controllers and offer an average access time of 25mS and a data transfer rate of 10 Megabits per second; the company claims the drives offer twice the speed of ST506/412 interface drives; each includes four platters and runs at track density of 1,440 tpi, or 19,405 bpi using 2.7 run-length-limited encoding; the model 14404 114Mb drive costs $1,500 is single quantities, the 140Mb model 14405 goes for $1,700, and the 170Mb 14406 is $2,000 – and newly-re-independent Century reckons they’re just the thing to supercharge IBM’s Personal System/2.
