Magnetic recording medium |
| abstract |
A magnetic recording medium comprises a non-magnetic substrate and a magnetic recording layer provided on said substrate, comprising (a) 100 parts by weight of magnetic powder, (b) 5 to 15 parts by weight of a mixture of a fatty acid ester and a fatty acid in their weight ratio of 60/40 to 95/5 and (c) 5 to 15 parts by weight of carbon black having an average diameter of a single particle in the range of 0.1 to 2.0 microns. The magnetic power has been preferably treated on the surface with (1) a phosphate or an alkenyl or alkyl succinic acid and (2) an organosilane compound having a hydrolyzable alkoxysilane group in a molecule. |
