A magnetic recording medium having a magnetic layer comprising ferromagnetic powder particles dispersed in a binder, wherein the ferromagnetic powder particles satisfy the condition represented by T&lt;600.times.10.sup.3 nm.sup.3 where T is an average value of volume T.sub.1 of each particle, where T.sub.1 is represented by T.sub.1 =L(nm).times.W(nm).times.W(nm) where L is the length of each particle and W is the width thereof, and the skewness in the distribution of the length L is at most 0.4.

Magnetic recording medium and process for its production

A magnetic recording medium having a magnetic layer which is formed by dispersing a magnetic powder and further an abrasive when necessary into a binder containing a sugar alcohol. The magnetic recording medium has excellent glossiness, squareness ratio and other surface properties due to the improvement of dispersibility of the magnetic powder and/or an abrasive when necessary.
