BS EN 61119-3 discusses the digital audio tape cassette system (DAT) with a focus on DAT calibration tape.
BS EN 61119-3 is the third part of the BS EN 61119 multi-series on digital audio tape cassette system that applies to the properties of magnetic tapes used in the DAT cassette system.
BS EN 61119-3 provides a purpose that specifies the measurement methods and the minimum requirements applicable to these tapes.
BS EN 61119-3 on DAT calibration tape is useful for:
The optimum recording current is the current required to record on the tape under test a square
wave with frequency 1/2 Tch that results in maximum playback output level. The optimum recording current of the reference tape is defined as the reference recording current.
BS EN 61119-3 discusses technical requirements and test conditions, electrical parameters to be measured, mechanical and other parameters to be tested, and reference tape.
BS EN 61119-3 will help you to understand the measurement methods and the minimum requirements applicable to these tapes.
