<p>A disk drive system employs uniform size data blocks, with each disk having a sectorized track format and each sector of a track including at least one servo burst. Data blocks exhibit a constant data density across a plurality of disk tracks of differing radii. The system comprises read/write apparatus (10,12) for accessing both servo signals and data signals in each disk sector. A servo system (20,30) is responsive to servo signals fed from the read/write apparatus (10,12) to generate a synchronizing signal (62). A data sector pulse generation circuit (60,70,72,74,76,78) is responsive to the synchronizing signal (62) to generate and pass to the read/write apparatus (10,12), a data sector pulse for each block of data commencing in a sector. That data sector pulse enables operation of the read/write apparatus (10,12) upon the data block. A control circuit (72,76) enables the delay of generation of a next data sector pulse when any block of data is split by a servo burst. The delay period is the duration of the servo burst and the portion of the data block that follows the servo burst. <IMAGE></p> |
