Abstract
Layer-type magnetic recording media are produced by dispersing a finely divided magnetically anisotropic material in a binder which consists of not less than 30% of a radiation-curable aqueous binder dispersion, applying the dispersion onto a non-magnetic base, orienting the magnetically anisotropic material and drying and crosslinking the applied layer by means of UV or high-energy electron radiation.
