Fixed disk drive

A higher performance, higher capacity, low cost fixed (Winchester) disk drive avoids the need of a servo surface and servo channel for head positioning by use of a mass balanced rotary actuator, a polyphase optical head position transducer coupled closely to the actuator and head position correction...

Zusammenfassung:	A higher performance, higher capacity, low cost fixed (Winchester) disk drive avoids the need of a servo surface and servo channel for head positioning by use of a mass balanced rotary actuator, a polyphase optical head position transducer coupled closely to the actuator and head position correction information sampled from the data surface by the data head.
