Abstract
The present disclosure includes systems and techniques relating to synchronization for writing to a recording medium. According to an aspect, an apparatus includes: circuitry configured to measure a timing difference based on a servo detect pulse and a write pulse, wherein the servo detect pulse comes from a detection of servo data from a recording medium including pre-defined data positions, and wherein the write pulse comes from a write clock signal used with the recording medium; and circuitry configured to control an adjustment to a phase of the write clock signal based on the timing difference to align the write clock signal with at least a portion of the pre-defined data positions.
