摘要：
A magnetic recording medium comprises a base film and a magnetic film having magnetic particles, formed on the base film. The magnetic film has a coercive force ranging from 750 Oe to 980 Oe and a residual magnetic flux density of 1,250 Gauss or over. In addition, the magnetic particles have a length of 0.2 .mu.m or below.
