Апстракт

<!-- NEW! -->IEC 62702-1-2:2022 is available as <a href="https://webstore.iec.ch/publication/76673">IEC 62702-1-2:2022 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>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.
