The ITU Radiocommunication Assembly,
considering
a) that the international exchange of monophonic and stereophonic sound programmes
between broadcasting organizations, recorded in analogue form, may be made by means of
b) that it is desirable to limit the number of standards and formats in which such recordings
may be exchanged;
c) that such exchanges would be facilitated by the use of uniform and widely accepted
specifications and operating practices;
d) the content of Resolution ITU-R 41 - Collaboration with the International Organization for
Standardization (ISO) and the international Electrotechnical Commission (IEC) on broadcasting
technologies,
- magnetic recordings on tape;
recommends
1 that, when such recorded sound programmes are exchanged in the form of analogue
magnetic recordings on tape, the exchanges should be effected by means of 6.3 mm wide tapes
(nominal value), recorded at a speed of 38.1 cmis or 19.05 cmís, conforming with IEC
Publication 94-1 (the "IEC-1" recording characteristics of IEC Publication 94-1 is preferred);
2 that the maximum diameter of exchanged full spools should be 290 mm (1 1.5 in.) for Type
I spools and 267.5 mm (10.5 in.) for Type II spools (see IEC Publication 94-1);
3 that the operating practices and additional requirements detailed below should be used for
such recorded sound programme exchanges.
