    Abstract: A light beam is scanned on a track of a recording medium, the track having a first track region and a second track region, each track region having a physical property that has recurring deviations. A wobble signal is derived from the light beam, the wobble signal having information associated with the recurring deviations. Whether the light beam is at the first track region or the second track region is determined based on a frequency, a period, or a pulse width of the wobble signal.

    Abstract: A detector is scanned across an optical storage medium having groove tracks and land tracks, each track having a wobble structure, to detect light reflected from the optical storage medium. A wobble signal and a tracking error signal are generated based on an output of the detector, and the wobble signal is sampled according to the tracking error signal. A determination about whether the detector is at the groove track or the land track is made based on the tracking error signal and a comparison of sampled values of the wobble signal.

    Abstract: An optical data accessing apparatus and method for changing the access from a first data layer to a second data layer of an optical storage medium are provided. The first data layer corresponds to a first SAC value, while the second data layer corresponds to a second SAC value. A processor of the optical data accessing apparatus is adapted for: (1) generating and sending a focus off signal to a pickup control unit to disable focus control; (2) generating a target value for an SAC to adjust an SAC value from the first SAC value to the target value, wherein the target value is between the first SAC value and the second SAC value; and (3) generating and sending a focus activation signal to the pickup control unit to re-enable the focus control to focus on the second data layer while the SAC value reaches the target value.
