Abstract

See full text

A magnetic recording medium having a metamorphosed layer on the surface of the magnetic layer of conventional magnetic recording media, said metamorphosed layer being derived from some of a binder component included in the magnetic layer, can prevent the sticking trouble taking place between the magnetic recording medium and the magnetic head. Said metamorphosed layer can be formed by irradiation with ultraviolet rays in the course of the production of magnetic recording media at the step of coating a dispersion of magnetic particles on a flexible support or after the coating step. Said metamorphosed layer can also be formed on the surface of once produced magnetic recording media irrespective of having caused the sticking trouble by irradiation with ultraviolet rays. Suitable apparatuses for producing such improved magnetic recording media are also provided.
