BS 7080-2:1989 is a British Standard titled "Guide to Construction and Use of 6.30 mm (0.25 in) Magnetic Tape Cartridge Using GCR for Data Interchange, Recording at 394 ftpmm (10,000 ftpi), 39 cpmm (1,000 cpi) - Streaming Mode." This standard provides guidelines for the construction and use of 6.30 mm wide magnetic tape cartridges designed for data interchange, using Group Code Recording (GCR) for data storage and retrieval.
Key elements of the scope of this standard include:
Recording Density: It specifies a recording density of 394 feet per millimeter (10,000 feet per inch) for linear recording, with 39 counts per millimeter (1,000 counts per inch) for the number of bits recorded per unit of tape length.
Track Format: The tape uses a streaming mode, which is a continuous method of data writing or reading, allowing for efficient sequential access. The standard describes the required track format for GCR recording on this tape.
Data Interchange: The standard defines how data can be interchanged between different systems that use this magnetic tape format, ensuring compatibility and reliability across devices.
Physical and Mechanical Properties: The guide includes recommendations about the construction, physical properties, and the mechanical features of the magnetic tape cartridge to ensure it meets the performance requirements for data storage and retrieval in streaming mode.
