Abstract

PURPOSE: To increase the performance of tape run through less friction with the pad, by providing the metal layer also at the back of the metal thin film type magnetic tape and providing high molecular coating layer on the both sides of fron of back.
CONSTITUTION: The metal magnetic substance layer 2 such as Co is formed on one side of the base 1 of high molecular film, and the non-magnetic substance metal layer 3 of Al is formed on another side. On the surface of the layers 2 and 3, the solution of high molecular material such as acryl resin mixed with the lubricant such as pentaerythritol tetrastearate, is coated and dried to form the high molecular coating layers 4 and 5. Thus, the unevenness of the rear surface can be avoided and the variation in the output can be reduced.
