    摘要: Optical disc apparatuses. The apparatus comprises an optical pickup and a data recovery unit. The optical pickup irradiates laser light onto a disc, receives light reflected from the disc, and generates an RF signal in response to the received light. The data recovery unit comprises a first configuration and a second configuration. The data recovery unit receives the RF signal from the optical pickup, reproduces data according to the RF signal in the first configuration, and performs a signal quality index measurement of the RF signal in the second configuration.

    摘要: 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.

    摘要: A method and an apparatus for deciding a spherical aberration compensation (SAC) value for an optical storage medium are provided. The optical storage medium comprises at least one recording layer and a cover layer. The SAC value is suitable for a selected one of the at least one recording layer. First, a focus search on the optical storage medium is performed to derive a focus error (FE) signal in response to a testing SAC value. Then, a center level and a center basis corresponding to the testing SAC value according to the FE signal is determined. The SAC value according to the center level, the center basis, and the testing SAC value is also determined. When the center level and the center basis are equal, the SAC value is determined to be the testing SAC value.

    摘要: A focus controller and a focus control method are provided. The method allows the optical access apparatus focus from a current data layer onto a target layer. Each of the current layer and the target layer corresponds to a Spherical Aberration Compensation (SAC) value and a focus error related parameter. The method adjusts the SAC value in use to a temporary SAC value, adjusts the focus error related parameter in use to a temporary focus error related parameter, focuses on the target layer, adjusts the focus error related parameter in use to the focus error related parameter corresponding to the target layer, and adjusts the SAC value in use to the focus error related parameter corresponding to the target layer.
