ABSTRACT:
Configuration for implementing a control unit of a disk apparatus having functions of high-precision head positioning control and data read/write control and sophisticated interface function with a small size and a low cost. A driver control microprocessor for embedded digital servo processing has a memory of a relatively small capacity and is suited for high-speed processing and an A/D converter. An interface function control microprocessor for generalized control of an interface function device with respect to a high rank device has a memory of a relatively large capacity and is suited for low-speed processing. The driver control microprocessor and the interface function control microprocessor are mounted within a single IC package.
