Abstract
A disk drive has a unified bus forming a signal path for transmitting register data, user data and servo sectors. The unified bus is connected between a channel circuit and a disk controller circuit. The channel circuit has an output stream engine which responds to and provides control signals to multiplex data on the unified bus at various times between demodulated user data, servo sector data and register data.
