Reproducer Test Tapes (also called -Alignment Tapes- or -Standard Tapes-) are used to standardize the azimuth, frequency-response characteristics, and recorded levels of magnetic sound recording systems. Informal -working standards- and formal standards exist; changes of these standards are discussed, as well as the possible confusion resulting therefrom. The manufacture of Reproducer Test Tapes is discussed, including special requirements for heads and blank tape, and the methods for determining the azimuth and the flux vs. frequency response characteristic. The small errors inherent in a new Test Tape may be greatly increased by accidental damage, and sometimes even in normal usage; handling techniques are described.
