Audio archive system - Part 1-2 : BD disk and data migration for long-term audio data storage
IEC 62702-1-2:2022 specifies a method of data-quality assurance for writable BD disks (hereafter referred to as "disks") which are specified for long-term data storage, and a data migration method which can sustain the recorded data on disks for long-term audio data preservation. 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.
Système d'archivage audio - Partie 1-2: Disque BD et migration de données pour le stockage à long terme des données audio
L'IEC 62702-1-2:2022 spécifie une méthode d'assurance de la qualité des données pour les disques BD inscriptibles (ci-après dénommés "disques") qui sont spécifiés pour le stockage à long terme des données, ainsi qu'une méthode de migration des données capable de conserver les données enregistrées sur les disques de manière à assurer la conservation à long terme des données audio. Les disques inscriptibles incluent les disques enregistrables BD (Blu-ray Disk) et les disques réenregistrables BD. L'IEC 62702-1-2:2022 annule et remplace la première édition parue en 2016. Cette édition constitue une révision technique. Afin de refléter les mises à jour apportées à l'ISO/IEC 29121:2021, cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) l'ISO/IEC 16963 a été identifiée comme méthode d'essai de référence pour l'estimation de la durée de vie;
b) des conditions ambiantes ont été ajoutées pour le mesurage de l'erreur de données maximale;
c) les exigences relatives aux unités d'essai ont été modifiées en fonction des conditions d'utilisation des utilisateurs;
d) les exigences relatives à la durée de vie estimée ont été définies de manière plus précise;
e) les exigences relatives à l'essai périodique de performances ont été définies de manière plus précise.

AUDIO ARCHIVE SYSTEM –
Part 1-2: BD disk and data migration for long-term audio data storage
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 62702-1-2:2017. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.
IEC 62702-1-2 has been prepared by technical area 6: Storage media, storage data structures,
storage systems and equipment, of IEC technical committee 100: Audio, video and multimedia
systems and equipment. It is an International Standard.
This second edition cancels and replaces the first edition published in 2017. 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.
The text of this International Standard is based on the following documents:
