METHOD OF COMPLEX QUALITY EVALUATION OF MAGNETICS TAPES FOR RECORDING AND REPRODUCTION OF SOUND

摘要

This invention relates to magnetic recording, namely, to compositions for producing the magnetic recording medium of the working layer. In order to increase the operational reliability of the operating layer of the magnetic recording medium is additionally introduced naftenathromaO, 1-2,0 wt.% Of mono- and / or the dimethyl benzene 2,0-7,0 wt.%. 4 yl., Table 8.
