ISO IEC 16382 pdf download Information technology — Data interchange on 1 2,7 mm 208-track magnetic tape cartridges — DLT 6 format
This International Standard specifies the physical and magnetic characteristics of a 12,7 mm wide,208-track magnetic tapecartridge, to enable physical interchangeability of such cartridges between drives. It also specifies the quality of the recordedsignals, a format – called Digital Linear Tape 6(DLT 6) – and a recording method, thereby allowing data interchange betweendrives. Together with a labelling standard,for instance International Standard IlS0 1001 for Magnetic Tape Labelling, it allowsfull data interchange by means of such magnetic tape cartridges.
2.1 Magnetic tape cartridges
A magnetic tape cartridge shall be in conformance with this International Standard if it satisfies all mandatory requirements ofthis Standard. The tape requirements shall be satisfied throughout the extent of the tape.
A system generating a magnetic tape cartridge for interchange shall be in conformance with this International Standard if allthe recordingas that it makes on a tape according to 2.1 meet the mandatory requirements of this International Standard.
In addition, a claim of conformance shall state
– whether or not one, or more registered algorithm(s) are implemented within the system, and are able to compress data
received from the host prior to collecting the data into blocks, and
– the registered identification number(s) of the implemented compression algorithm(s).2.3Receiving systems
A system receiving a magnetic tape cartridge for interchange shall be in conformance with this nternational Standard if it isable to handle any recording made on a tape according to 2.1.
In addition, it shall
whether or not one, or more de-compression algorithm(s) are implemented within the system, and are able to be applied tode-compress data prior to making such data available to the host,
the registered identification number(s) of the implemented compression algorithm(s).

4 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
4.1Average Signal Amplitude: The average peak-to-peak value of the output signal from the read head at the physical
recording density of 2578 ftpmm measured over a minimum length of track of 25,4 mm, exclusive of missing pulses.
