This standard establishes the format of information on 19-mm type ID-1 instrumentation digital cassettes. It specifies the dimensions and locations of the helical data, control, time code,
and annotation tracks. It defines the format and recording requirements of the data blocks
forming the helical data record containing digital instrumentation and other associated data, and
specifies the content, format, and recording method for the control record. This standard also
specifies the recording requirements for the longitudinal records contained in the annotation
and the time code tracks. The physical requirements, magnetic requirements, and test
methods for the magnetic tape and tape cassette are not specified in this standard, but can be
found in the references or in the technical literature. No licenses for patented or copyrighted features are required to implement compliance with this standard. All dimensions given are metric.
