Abstract: A method and apparatus is disclosed for compensating for spindle Repetitive Runout (RRO) by writing a servo parameter information field for both read and write tracks. Servo burst patterns may be written by servo writer during drive assembly and may be used to independently position write and read track servo parameter fields for writing in corrected positions. In track following mode, RRO may be calculated over several revolutions and average RRO calculated and stored. Position error values corresponding to RRO for every servo parameter and, thus, every sector, may also be stored in servo parameter gray code fields for both read and write tracks. Servo parameter information may be read back and decoded in a present sector for head position correction in subsequent sectors. For small offset, one servo parameter may be read to correct both read and write track center deviations.
