METHOD AND APPARATUS FOR STORING DATA TO A STORAGE MEDIUM, METHOD AND APPARATUS FOR CORRECTING ERRORS OCCURRING WHILE DATA IS READ FROM A STORAGE MEDIUM, AND STORAGE MEDIUM

摘要

AV content stored on prerecorded storage media often does not entirely consume the available media capacity, and an unused special area will remain. Also, known recording formats often provide areas which are free from any information that is relevant for reproduction and, therefore, represent a further special area. The invention proposes to derive safety information from the data of the known recording format, to embed the safety information into the special areas, to store it along with the data, and to use the safety information for restoration of the read data in the event errors are occurring. Preferably, the safety information of a specific section is stored to special areas of a previous section, thus allowing real-time correction.
