Abstract
A method and apparatus for data retrieval from a storage media, such as magnetic disk drive. A synchronization detector decodes the synchronization information from either the first or second synchronization mark. A later stage detector then carries out several decoding iterations using the synchronization information from the synchronization detector and data stored in the first and second memories. Loss of the data between the first synchronization mark and the second synchronization mark, if there is a problem with the first synchronization mark, is avoided because the bit stream is stored in the first memory.
