A recording medium, such as a high-density and/or optical recording medium including segment information recorded thereon, and apparatus and methods for recording to and reproducing from the recording medium, in order to improve data protection, data management and/or reproduction compatibility. The recording medium may contain at least one segment area which is an area on the disc controlled by a plurality of valid PACs and if the designated segment areas overlap with one another, control information of the respective PACs which control the overlapped area may be applied to control the overlapped area.
Cette invention concerne un support d'enregistrement tel qu'un support d'enregistrement haute densité et/ou optique comprenant des informations en segments, ainsi qu'un dispositif et des procédés permettant d'enregistrer des données sur ce support et de reproduire des données à partir de ce support dans le but d'améliorer la protection, la gestion et/ou la compatibilité de reproduction des données. Le support d'enregistrement peut contenir au moins un segment qui, sur le disque, est commandé par une pluralité de commandes à accès physique (PAC) valides. Si les zones de segments désignées se chevauchent, l'information de commande des PAC respectifs qui commande la zone de chevauchement peut être utilisé pour gérer ladite zone.
