Abstract
A method to determine a relative delay between a current-overshoot signal and a write data signal for a hard disk drive preamplifier, the method including using a memory element to strobe a test current-overshoot signal with a test data signal; counting a number of strobed transitions of the test current-overshoot signal; adjusting the delay based on the number of strobed transitions; setting a phase difference between the current-overshoot signal and the write data signal according to the delay; and using the memory element to strobe the current-overshoot signal with the write data signal.
