MATERIAL REQUIREMENTS FOR HIGHLY DURABLE MAGNETIC RECORDING TAPE.

To obtain highly durable magnetic recording tape, the authors investigated the relation between tape component materials and the tape wearing due to high temperature and humidity in the environment or abrasion during uses, its physical deformation, adhesiveness between tape layers and dropout error. As a result, suitable material conditions have been obtained. This paper reports the causes of adhesiveness referring to the results of material analysis, and proposes an effective estimation method for the adhesiveness of the painted film.
