Method and apparatus for decoding a data sector including user data and non-user data

摘要

The disclosure provides a method that includes receiving a data sector of a plurality of data tiles, wherein each of the plurality of data tiles includes either nuisance data or user data, decoding the received data sector, using an error correction code, to generate a decoded data sector, and determining an error in the decoded data sector. The method further includes identifying, in response to determining the error, at least one data tile from a first plurality of data tiles, such that each of the identified at least one data tiles potentially includes nuisance data, and generating a modified data sector from the received data sector, by correcting at least one of the at least one data tiles in the received data sector.
