Abstract
The magnetic recording medium comprises a substrate, a recording coating of a ferromagnetic metal and an aromatic organic polymer having a weight-average molecular weight of 1,000 to 5,000,000. The magnetic recording medium is produced by a plating method or a vaporization method so as to form co-deposition of the metal and the polymer. The magnetic recording medium produced is improved in resistance to corrosion.
