Information technology — Streaming Lossless Data Compression algorithm (SLDC)

ISO/IEC 22091:2002 specifies a lossless compression algorithm to reduce the number of 8-bit bytes required to represent data records and File Marks. The algorithm is known as Streaming Lossless Data Compression algorithm (SLDC). ISO/IEC 22091:2002 is based on ISO/IEC 15220. It extends that algorithm with the addition of control symbols that allow records of different sizes and compressibility, along with File Marks, to be efficiently encoded into an output stream which requires little or no additional control information for later decoding. The numerical identifier according to ISO/IEC 11576 allocated to this algorithm is 6.

Information technology — Data compression for information interchange — Adaptive coding with embedded dictionary — DCLZ Algorithm

Specifies a lossless compression algorithm (DCLZ - Data Compression according to Lempel and Ziv) to reduce the number of bits required to represent information coded by means of 8-bit bytes. This algorithm is particularly useful when information has to be recorded on an interchangeable medium. Its use is not limited to this application.

Information technology — Linear tape file system (LTFS) Format specification

This document defines the LTFS Format requirements for interchanged media that claims LTFS compliance. Those requirements are specified as the size and sequence of data blocks and file marks on the media, the content and form of special data constructs (the LTFS Label and LTFS Index), and the content of the partition labels and use of MAM parameters. The data content (not the physical media) of the LTFS format shall be interchangeable among all data storage systems claiming conformance to this format. Physical media interchange is dependent on compatibility of physical media and the media access devices in use. NOTE: This document does not contain instructions or tape command sequences to build the LTFS structure.

Information technology — Volume and file structure of write-once and rewritable media using non-sequential recording for information interchange — Part 3: Volume structure

ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume structure, file structure and record structure for the interchange of information on media between users of information processing systems. The media shall be recorded as if the recording of sectors may be done in any order. Note 1 - The medium is not restricted to being of only one type; the type of medium may be either write once, or read only, or rewritable, or a combination of these types. ISO/IEC 13346 consists of the following five Parts: Part 1: General Part 2: Volume and Boot Block Recognition Part 3: Volume Structure Part 4: File Structure Part 5: Record Structure Annex A - ICB Strategies, is part of ISO/IEC 13346-4. This part of ISO/IEC 13346 specifies a format and associated system requirements for volume structure by specifying: the attributes of a volume and the descriptors recorded on it; the relationship among volumes of a volume set; the attributes of a partition of a volume; the attributes of a logical volume and the descriptors recorded on it; levels of medium interchange; requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems; for this purpose, it specifies the functions to be provided within systems which are intended to originate or receive media which conform to this part of ISO/IEC 13346.
