ABSTRACT:
A disk sequencer uses control words to identify starts and splits in headerless data sectors. Each control word indicates an event-count, an initial event, and a terminal event. The initial event, which can be an EOS pulse, a sector pulse, or a data sync pulse, synchronizes the start of a count until the terminal event. The terminal event causes either generation of a sector pulse indicating a start of a data sector or an interrupt indicating a split in a data sector. A disk sequencer includes an event counter and a data segment sequencer. The event counter starts counting at the initial event, counts the event-count, and generates the sector pulse or interrupt at the end of the event-count. A sector pulse starts a data segment sequencer processing a first data segment of a data sector. The interrupt causes the data segment sequencer to execute an interrupt routine for fields surrounding a servo sector. After an EOS pulse and completion of the interrupt routine, the data segment sequencer resumes processing the data sector by processing a second or subsequent data segments in the data sector.
