Title (EN) STORAGE MEDIUM, REPRODUCING METHOD, AND RECORDING METHOD
(FR) SUPPORT D'ENREGISTREMENT, PROCEDE DE REPRODUCTION ET PROCEDE D'ENREGISTREMENT
Abstract: front page image
(EN)BCA data includes two BCA preambles, two BCA postambles, and two BCA data areas. BCA error detection codes and BCA error correction codes are added to each BCA data area. The same items of information are multiply recorded in the two BCA data areas. Even if one item of data cannot be reproduced under the influence of dust or scratch produced on a surface of a storage medium, data can be reproduced from the other BCA data area, and the reliability of the data is improved.
(FR)Des données BCA contiennent deux synchroniseurs initiaux BCA, deux synchroniseurs finaux BCA, et deux zones de données BCA. Des codes de détection d'erreurs BCA et des codes de correction d'erreurs BCA sont ajoutés à chaque zone de données BCA. Les mêmes éléments d'information sont enregistrés à la fois dans les deux zones de données BCA. Même si la présence de poussière ou d'une rayure sur la surface d'un support d'enregistrement empêche la reproduction de l'un des éléments de données, lesdites données peuvent être reproduites à partir de l'autre zone de données BCA, ce qui améliore la fiabilité des données.
