ABSTRACT:
Magnetic recording media highly loaded with magnetic oxide particles. This media possesses a very smooth surface finish, and in operation exhibits low media wear, as well as low wear of an associated transducing head. This media includes an internal lubricant tridecyl stearate; i.e. a linear, 31-carbon fatty acid ester molecule formed by the ester linking of 13-carbon tridecyl alcohol and 18-carbon stearic acid, the molecule having the composition ##STR1##
