Abstract

Wenn Fehler auf optischen Platten gehandhabt werden unter Verwendung von nicht fehlerbehafteten Bereichen anstelle von fehlerhaften Bereichen, werden verschiedene Kriterien zur Erfassung der Fehler verwendet in Abhängigkeit von dem Typ der Daten, die auf der Platte aufgezeichnet werden. Beispielsweise werden weniger strenge Kriterien verwendet, um eine Unterbrechung der Echtzeit-Aufzeichnung zu vermeiden, wenn Audio- oder Videodaten aufgezeichnet werden, als wenn Computerdaten aufgezeichnet werden. Die Kriterien selbst können ebenfalls auf der Platte aufgezeichnet werden.When errors are handled on optical disks using non-defective areas instead of defective areas, various criteria are used to detect the errors, depending on the type of data recorded on the disk. For example, less stringent criteria are used to avoid interrupting real-time recording when recording audio or video data than when recording computer data. The criteria themselves can also be recorded on the disk.
