Abstract

PURPOSE: To enable to form suitable magnetic layer having excellent dispersibility of magnetic powder and bondingness of base and further, excessive mechanical strength, by taking the material for the base as aromatic polyamide system resin and taking the binder for the magnetic layer as specific resin.
CONSTITUTION: On the base preferably about 3μ thick consisting of aromatic polyamide system resin, the magnetic layer is placed, which takes vinylchloride-vinyl acetate copolymer system resin, urethane prepolymer of 5 to 50 wt.%, preferably 10 to 30 wt.% to the total amount, and low molecular and more functional isocyanate compound of 1 to 30 wt.%, preferably 2 to 20 wt% to the entire binder components, as the binder. Thus, even if the total thickness of magnetic recording media is thin, the mechanical strength can sufficiently be held and the recording and reproducing time can be extended.
