The writable disks include BD recordable disk and BD rewritable disk. IEC 62702-1-2:2022 cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. In order to reflect the updates to ISO/IEC 29121:2021, this edition includes the following significant technical changes with respect to the previous edition: a) ISO/IEC 16963 has been identified as the referee test method for the estimation of lifetime; b) the ambient conditions for the measurement of maximum data error have been added; c) the requirements for test drives have been changed considering the use condition of users; d) the requirements for the estimated lifetime have been defined more clearly; e) the requirements for the periodic performance test have been defined more clearly. IEC 62702-1-2:2022 est disponible sous forme de IEC 62702-1-2:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente.LIEC 62702-1-2:2022 specifie une methode dassurance de la qualite des donnees pour les disques BD inscriptibles (ci-apres denommes "disques") qui sont specifies pour le stockage a long terme des donnees, ainsi quune methode de migration des donnees capable de conserver les donnees enregistrees sur les disques de maniere a assurer la conservation a long terme des donnees audio. Les disques inscriptibles incluent les disques enregistrables BD (Blu-ray Disk) et les disques reenregistrables BD. LIEC 62702-1-2:2022 annule et remplace la premiere edition parue en 2016. Cette edition constitue une revision technique. Afin de refleter les mises a jour apportees a lISO/IEC 29121:2021, cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) lISO/IEC 16963 a ete identifiee comme methode dessai de reference pour lestimation de la duree de vie; b) des conditions ambiantes ont ete ajoutees pour le mesurage de lerreur de donnees maximale; c) les exigences relatives aux unites dessai ont ete modifiees en fonction des conditions dutilisation des utilisateurs; d) les exigences relatives a la duree de vie estimee ont ete definies de maniere plus precise; e) les exigences relatives a lessai periodique de performances ont ete definies de maniere plus precise.
