Audio archive system - Part 1-2 : BD disk and data migration for long-term audio data storage
IEC 62702-1-2:2022 is available as IEC 62702-1-2:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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.

64 Part 1-2: BD disk and data migration for long-term audio data storage
66 FOREWORD
67 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
68 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
69 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
70 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
71 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
72 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
73 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
74 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
75 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
76 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
77 consensus of opinion on the relevant subjects since each technical committee has representation from all
78 interested IEC National Committees.
79 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
80 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
81 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
82 misinterpretation by any end user.
83 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
84 transparently to the maximum extent possible in their national and regional publications. Any divergence between
85 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
86 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
87 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
88 services carried out by independent certification bodies.
89 6) All users should ensure that they have the latest edition of this publication.
90 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
91 members of its technical committees and IEC National Committees for any personal injury, property damage or
92 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
93 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
94 Publications.
95 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
96 indispensable for the correct application of this publication.
97 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
98 rights. IEC shall not be held responsible for identifying any or all such patent rights.
99 IEC 62702-1-2 has been prepared by technical area 6: Storage media, storage data structures,
100 storage systems and equipment, of IEC technical committee 100: Audio, video and multimedia
101 systems and equipment. It is an International Standard.
102 This 2nd edition cancels and replaces the 1st edition published in 2017-11-07. This edition
103 constitutes a technical revision.
th
104 Reflect the update of the reference standard ISO/IEC 29121 4 edition that has been published,
105 this edition includes the following significant technical changes with respect to the previous
106 edition:
107 a) ISO/IEC 16963 has been identified as the referee test method for the lifetime estimation;
108 a) the ambient conditions for the measurement of maximum data error have been added;
109 b) the requirements for test drives have been changed considering the use condition of users;
110 c) the requirements for the estimated lifetime have been defined more clearly;
111 d) the requirements for the periodic performance test have been defined more clearly.
