Il a déjà fonctionné par le passé. The IBM 62PC (Piccolo) 65MB capacity drive introduced in 1979 used six 8- inch disks with one surface dedicated to servo position data. The drive employed a sector servo position control and a rotary voice coil actuator to eliminate temperature effects. The lower power consumption of the small disk diameter eliminated the need for external air cooling and simplified integration of the unit as subsystem into a variety of machines. A sealed disk enclosure design assured a reduction in disk surface contamination and improved reliability. IBM also sold the unit as the 3310 attachable direct access storage device (DASD). 360,000 units were shipped from Jan 1979 through Feb 1990. En savoir plus Collaboration commerciale.
