    • An archiving system including one or more removable disk drives embedded in removable disk cartridges, referred to simply as removable disk drives. The removable disk drives allow for expandability and replacement such that the archiving system need not be duplicated to add new or more storage capacity. In embodiments, the removable disk drives store metadata that contain information about the data stored on the removable disk drive. The metadata allows the system to retrieve the correct data from the random access memory and establishes controls on the data stored on the removable disk drive. In embodiments, the metadata is stored in two locations, such that, if the metadata in one location is corrupted, the second copy of the metadata may be retrieved.

    • Data for recordation on a video disc is given multi-redundancy at block, field and group levels. Raw data is filled typically serially row by indexed row of 8-bit words with at least one and preferably 3 words being auxiliary check words derived from the remainder of the data field of the block. Block filling is completed with the addition of preferred Reed/Solomon error-correction redundancy filling two rows for column error detection and correction and two columns for row error detection and correction. Thirty blocks, so prepared, are processed to obtain two redundant blocks, completing a 32-block data field. Writing the data onto the video disc occurs with a three-dimensional diagonal interleave at the field level. After interleave each field is additionally XORd with 62 other fields to create a redundant field. This redundant field plus the 63 data fields comprise a group. The group of fields is written to the video disk so as to maximally spatially separate adjacent fields. Recording occurs via an optical master disc. Stamped replications (video discs) are made from the master disc. Data from the video discs is decoded accordingly.
    • 视频盘上记录的数据在块,字段和组级别被给予多重冗余。 原始数据通常由具有至少一个且最好是3个字的8位字的索引行按顺序填充,是从块的数据字段的其余部分导出的辅助检查词。 通过添加优选的Reed / Solomon纠错冗余填充两行用于列错误检测和校正以及两列用于行错误检测和校正,完成块填充。 如此准备的三十个块被处理以获得两个冗余块,完成一个32块数据字段。 将数据写入视频光盘是在现场级别进行三维对角线交错的。 交织后每个字段另外XORd与其他62个字段创建一个冗余字段。 该冗余字段加上63个数据字段组成一个组。 该字段组被写入视频磁盘,以便最大限度地在相邻的字段之间进行空间分隔。 通过光学母盘进行记录。 冲压复制(视频光盘)由主光盘制成。 相应地解码来自视频盘的数据。
