초록

Selected chemical, physical, mechanical, and magnetic properties of magnetite, Co-${\gamma}-Fe_2O_3$, $CrO_2$ recording tapes were studied, under three sets of temperature and humidity conditions, to accelerate the tapes' aging. The results. obtained indicated that changes in temperature, huminity and magnetic properties were dependent. Changes in the magnetic properties can be used to predict the life expentancy of the information stored in the media. Together, all of these properties can be used to assess the overall storage characteristics of magnetitie, Co-${\gamma}-Fe_2O_3$, $CrO_2$ recording tapes.
