摘要： An apparatus for finding a syncmark in a data sector includes a syncmark detection circuit, decoder, fragment information table and syncmark recovery circuit. The syncmark detection circuit is operable to detect a syncmark in each of a number of fragments of the data sector and to compute a syncmark quality for each of the syncmarks. The decoder is operable to apply a data decoding algorithm to encoded data for the data sector. The encoded data has start points identified by the syncmark in each of the fragments. The fragment information table stores the syncmark quality for each of the syncmarks. The syncmark recovery sweeps the start points over search ranges for selected fragments for which the syncmark detection circuit failed to detect the syncmark and which have a lower syncmark quality than others of the fragments.

摘要： A system includes a first sync mark detector circuit operable to apply a first sync mark detection algorithm to search a received media sector and overhead for a second sync mark after a failure to identify a first sync mark. A second sync mark detector circuit operable to apply a second sync mark detection algorithm to search the received media sector and overhead for the second sync mark. An anchor point identification circuit identifies an anchor point in the received media sector. A retry controller circuit causes a re-read of the received media sector and overhead when the first sync mark detector circuit fails to identify the first sync mark, and aligns the received media sector to yield an aligned media sector. A data processing circuit recovers an original user data set from the aligned media sector.
