Magnetic tape sound recording and reproducing systems - Part 5: Electrical magnetic tape properties

Applies to non-perforated magnetic tape used for professional and domestic analogue sound recording and reproduction. Lists and defines the characteristics, methods of measurement and equipment necessary to determine the electrical properties of magnetic tapes. Will also enable users of magnetic tapes to compare the technical product data of different manufacturers, produced in accordance with this standard.

Systeme für Tonaufzeichnung und -wiedergabe auf Magnetband - Teil 5: Elektrische Eigenschaften von Magnetbändern

Systèmes d'enregistrement et de lecture du son sur bandes magnétiques - Partie 5: Propriétés électriques des bandes magnétiques

S'applique aux bandes magnétiques non perforées à usages professionnels et grand public pour l'enregistrement analogique et la lecture du son. Etablit les caractéristiques électriques des bandes magnétiques et définit les méthodes et les matériels de mesure nécessaires. Permet aux utilisateurs de bandes magnétiques de comparer les informations techniques données, conformément à la présente norme, par divers fabricants.
