Abstract
A system and method for enabling a programmed phase change in a servo track writer (STW) clock providing signals for writing information to a servo track, the phase change programmed to occur in one or more large or small phase bumps in either positive and negative directions, whereby a large phase jump is defined as the largest block of bit unit that can be handled without introducing noise into the system, and a smaller phase bump that is the smallest incremental bit unit that may be programmed to change the servo write clock phase until a final phase offset is reached.
