标准摘要
[中文适用范围]： 本部分 IEC 62702 规定了用于长期数据存储的可写 BD 光盘（以下简称“光盘”）的数据质量保证方法，以及可以维持光盘上记录数据以进行长期音频数据保存的数据迁移方法。可写光盘包括 BD 可录光盘和 BD 可重写光盘。 [外文原描述]： IEC 62702-1-2:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
