Abstract
An apparatus which records/reproduces data with respect to an optical recording medium, includes a data processing unit which detects a phase difference between a phase reference signal and a groove wobble signal detected from the optical recording medium, and compensates for the phase difference and performs a signal processing to record data on or reproduce data from the optical recording medium in response to the phase difference being equal to or greater than a predetermined reference value. By detecting a phase difference between a phase reference signal and a wobble signal and compensating for the phase difference, a recording of data on and a reproducing of data from the optical recording medium can be more accurately performed.
