Abstract
Aspects of the disclosure provide a method for efficiently calibrating an optical recording device. The method can include receiving a first signal corresponding to a wobbled track of a memory medium, phase-locking a second signal to the first signal, the second signal being used to extract embedded information in the wobbled track, and determining an optimum setting of the optical recording device based on a locking quality of the first signal and the second signal.
