INFORMATIONSAUFZEICHNUNGSVORRICHTUNG FÜR DIE RESERVIERUNG VON ZUSAMMENHÄNGENDEN BEREICHEN UM DIE KONTINUIERLICHE WIEDERGABE VON AUDIOVISUELLEN DATEN SICHERZUSTELLEN

摘要

A CDA processing section 142 extracts an unused area of an information recording medium 16 via a disc status management section 145 and a drive control section 15. The CDA processing section 142 divides the extracted unused areas by a division criteria value MAS, which allows continuous reproduction of a video and audio stream, and reserves areas having the size of the division criteria value MAS as CDAs. This enables continuous reproduction of AV data, and multiple data can be recorded simultaneously.
