PURPOSE: To obtain a magnetic recording medium having superior magnetic characteristics and superior surface smoothness of the magnetic layer and contg. magnetic powder with high dispersibility and fillability by hardening a coated film contg. a specified coupling agent, a specified oligomer and magnetic powder under radiation so as to produce the magnetic layer.

CONSTITUTION: A coated film contg. a titanium coupling agent represented by the general formula, an oligomer obtd. by bonding acrylic acid or methacrylic acid to a terminal of oligoester consisting of phthalic acid and alkylene glycol by esterification, and magnetic powder, is formed on a substrate and hardened by irradiation to produce a magnetic layer. The preferred amount of the coupling agent to be used is 0.1W10wt% of the amount of the magnetic powder in the magnetic layer, and that of the oligomer to be used is 20W60wt% of the total amount of the powder and the coupling agent.
