This standard provides instrumentation tape and recorder/reproducer characteristics and modes of recording to allow users of different systems to interchange analog data recorded on instrumentation magnetic tape. This standard deals solely with the requirements for recording on magnetic tape. Compliance with the proposed standard for unrecorded tape, American National Standard for Information Systems - Unrecorded Magnetic Tape for Longitudinal Recording of Instrumentation Data - Interchange, X3 project 747-0, ') will be a requirement for information exchange.
