    Abstract: A method applied to an optical disc drive for calculating an error detection code corresponding to a data sector is disclosed. The data sector includes a plurality of bytes arranged in a matrix having N lines along a first direction and M lines along a second direction perpendicular to the first direction. The method includes: along the first direction, calculating error detection codes corresponding to M bytes located at each of the N lines, wherein for each of the N lines, only bytes having error bits affect an error detection code for the line; adjusting an error detection code of each of the N lines according to a displacement between each of the N lines and a last line of the N lines; and then determining the error detection code of the data sector by summing up the displacement-adjusted error detection code of each of the N lines.

    Abstract: A method for generating error detection code is disclosed. Firstly, a first error detection code PEDC is derived by using 12-byte unknown sector data information including ID, IED, RSV and the 2048-byte main data while the main data is delivered from a host. Secondly, a second error detection code MEDC is obtained by using known 12-byte sector data information including ID, IED, RSV and the 2048-byte main data. Thereafter, the real error detection code EDC is obtained by applying an exclusive-OR operation to both the PEDC and MEDC.

    Abstract: A method for fabricating fine reduced iron powders comprises the following steps: heating fine iron oxide powders having a mean particle size of smaller than 20 μm to a reduction temperature of over 700° C. to reduce the fine iron oxide powder into iron powders that are partially sintered into iron powder agglomerates; and performing a crushing-spheroidizing process on the iron powder agglomerates to obtain individual iron powders having a mean particle size of smaller than 20 μm. The method can reduce iron oxide powers into iron powders having a rounded shape and a high packing density and a high tap density, which are suitable for the metal injection molding process and the inductor fabrication process. The reduced iron powder may further be processed using an annealing process and a second crushing-spheroidizing process in sequence to further increase the sphericity, packing density, and tap density of the reduced iron powder.

    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: 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.
