Codes for 6.3 mm twin track magnetic tape and recording/reproducing equipment for professional use.

Section 2 applies to a time reference (80 bit time code according to IEC Publication 461) located on a track half-way between the two audio tracks of a 6.3 mm wide professional twin track magnetic tape for use at a tape speed of 19 cm/s or 38 cm/s.

Section 3 applies to an address code in the form of intentional pauses within a programme for the automatic recognition of individual parts of the programme.

Section 2. Time and control code (IEC publication 461) for 6.3 mm wide twin track audio tape

2 General test conditions

The characteristics of the equipment shall be measured under the following conditions:

– at rated mains voltage;
– at rated mains frequency;
– ambient temperature between 15 °C and 35 °C;
– relative humidity between 45 % and 75 %;
– at 86 kPa to 106 kPa atmospheric pressure;
– after at least 10 min operation.
