Abstract:
A disk drive comprising:a disk comprising a track having a data sector and a servo sector; a channel circuit; a disk controller circuit; a unified bus connected between the channel circuit and the disk controller circuit and having a data-carrying medium; the channel circuit comprising: a channel register for storing register data; means for receiving and demodulating a first series of signals representing data stored in the servo sector to create a first demodulated series of signals; means for receiving and demodulating a second series of signals representing data stored in at least a portion of the data sector to create a second demodulated series of signals; a channel output stream engine coupled to the unified bus for transmitting and receiving the register data and for transmitting the first and second demodulated series of signals on the data-carrying medium; wherein during a first interval the data-carrying medium reflects the register data, during a second interval the data-carrying medium reflects the first demodulated series of signals, and during a third interval the data-carrying medium reflects the second demodulated series of signals.
