Magnetic recording medium and method for making the same.

摘要

In the magnetic recording medium, the back coat layer (3) which includes polyurethane having a Tg ( the glass-transition temperature) under the room temperature, isocyanate hardener, carbon powder and inorganic abrasive pigment is formed on opposite face of the non-magnetic substrate(1)to the one face covered by the magnetic recording film(2).Owing to the back coat layer, improved characteristic of contact with post and the like is obtained, smooth running condition under small tention was realized, and the magnetic recording medium making small head wear, and having improved wear resistance is obtained.
