Abstract :
Selected chemical, physical, mechanical, and magnetic properties of Fe metal recording tapes were studied, under three sets of temperature and humidity conditions, to accelerate the tapes´ aging. The results obtained indicated that changes in cupping and magnetic properties were independent of the tape binder, while the friction of the magnetic coating side of the tape was binder-dependent. Changes in the saturation and the remanent magnetic moments were particle-dependent. The chemical properties of the binder systems were not significantly affected by the accelerated aging. Based on these results, the useful life of the tapes was projected
