System and method for data error recovery on optical media utilizing hierarchical recovery techniques

摘要

A system and method for data error recovery uses a plurality of error correction routines in an attempt to provide data that can be used by the end user. In some situations the user is prompted for additional information and in some situations the data is provided with the errors highlighted. This system minimizes the amount of data that is unrecoverable. The system will work with CD discs or other storage media as well as with data lost by communication failures.
