标准摘要
[中文适用范围]： : 本标准规定了用于长期音频数据存储的BD光盘及其数据迁移的技术要求、测试方法和管理指南。适用于音频数据的长期存储和迁移，以确保数据的完整性和可访问性。 [外文原描述]： 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.
