Abstract: A timing jitter measurement circuit for measuring timing jitter in the digital domain may use an interpolator bank to over-sample a signal from a media reader, a zero crossing estimator to estimate a zero crossing moment in the output of the interpolator bank and a time interval analyzer (TIA) to calculate the timing jitter as the deviation of the estimated zero crossing moment from an expected zero crossing moment in a clock signal. The timing jitter measurement circuit may be integrated into digital circuitry since it avoids using analog devices. Consequently, it may simplify the chip design, lower power consumption and save space.

Abstract: Aspects of the disclosure provide a method for signal processing. The method includes receiving a tracking signal corresponding to a recording track on a storage medium. The tracking signal is frequency modulated with encoded symbols. Further, the method includes phase-locking an internal signal to the tracking signal to cause a frequency of the internal signal to be locked at a center frequency of the tracking signal, detecting a drift between the internal signal and the encoded symbols, and phase-shifting the internal signal to compensate for the drift.

Abstract: A method and apparatus for recovering clock timing from a hi-phase modulated portion of an HFM signal. The signal includes transitions between high and low levels. A clock count is initiated upon detection of a first transition, which corresponds to an expected clock timing of the signal. The count is stopped upon detection of a second transition. An actual clock count includes a number of clock cycles occurring between the transitions based on the expected timing. A first expected clock count between transitions is identified if the actual clock count between the transitions falls within a first range of clock counts. A first error between the actual and first expected clock counts is determined. A second expected clock count between transitions is identified if the actual clock count between transitions falls within a second range of clock counts. A second error between the actual expected clock counts is determined.
