Abstract:
1. A hard disk drive, comprising: a servo controller driving a voice coil actuator to at least partly read position at least one read head to read access a read track on at least one rotating disk surface; a computer directing said servo controller to read with a read head a read track on a rotating disk surface within said hard disk drive; said computer is accessibly coupled to a memory; wherein said computer is directed by a program system including program steps residing in said memory, comprising the program steps: determining the read PES burst pattern of said read track; using the read track position of said read track to find a nearest write track position for a write track; predicting the write PES burst pattern of said write track; and adjusting said read position of said read head by the Burst Correction Value of said write track whenever said write PES burst pattern matches said read PES burst pattern; wherein the program step determining said read PES burst pattern, further comprises the program step: accessing a track location table to at least partly derive said read PES burst pattern for said read track position; wherein the program step using said read track position to find said nearest write track position, further comprises the program step: looking-up in said track location table to find said nearest write track position to said read track position; wherein the program step predicting the write PES burst pattern of said write track, further comprises the program step: accessing said track location table to at least partly derive said write PES burst pattern at said nearest write track position.
