Abstract
A sector pulse generator circuit for a hard disk drive assembly includes an angular position counter, a sector counter, a sector limit register, and a pulse generator. The circuit generates a sector pulse when the count in the angular position counter equals the count in the sector counter. When the count in the angular position counter exceeds the count in the sector counter, the sector counter is incremented by the number of clock pulses in a sector of the current track. The sector limit register stores the number of complete sectors in the current track.
