Abstract: An apparatus and method for accessing data from a storage medium is disclosed. The apparatus fetches a data block from the storage medium via an accessing unit, and corrects an error of the data block by an error correction code (ECC) decoder according to an ECC of the data block. The apparatus also includes an error detection code (EDC) processor for calculating an EDC of each data sector of the data block, and a flag register for storing a flag associated with each data sector. The method includes re-fetching a data sector if the associated flag indicates the EDC of the data sector is incorrect; and bypassing a data sector if the associated flag indicates that the EDC of the data sector is correct, even though the ECC of the data block indicates that the data sector contains an error.

Abstract: An optical storage system includes a pickup head for picking up data from a storage medium. Firstly, the maxima of a tracking error signal and runout are obtained in a calibration procedure in a close loop formed by an optical pickup head, a pre-amplifier, a compensator, a band-pass filter and a maximum detector. A calibration factor is then defined and derived by using the obtained maxima and nominal factors of a power amplifier and the optical pickup head of the optical storage system. The path formed by the series-connected band-pass filter and maximum detector is then disabled, while the calculated calibration factor is then stored in the compensator. The optical storage system may operate in a close loop formed by the optical pick head, pre-amplifier, compensator, a power amplifier under a normal operation procedure so that the optical storage system may record or read data onto/from an optical disc under the compensation provided by the calibration factor.

Abstract: A method for accessing data from a storage medium according to requirements of a host is disclosed. The storage medium stores a plurality of data blocks that each one of them further includes a plurality of data sectors and an error correction code used for recovering errors of the data block. Each one of the data sectors further includes an error detection code used for detecting correctness of associated data sector. When a data block is verified to include at least one incorrect data sectors by means of the error detection codes, those correct data sectors rather than all the data sectors are stored into a specific position of a data buffer. The whole data block is next re-fetched and stored into the same position of the data buffer used to occupied by the data block, those stored correct data sectors are then re-fetched to overwrite corresponding ones in the data buffer. Thereafter, the incorrect data sectors are re-detected to verify their correctness again. Not only those correct data sectors will be faultless protected, but also upgrade data access performance.
