A problem to be solved by the present invention is to provide a magnetic recording medium having a jet-black magnetic stripe which is not tinged with red. The present invention is directed to a magnetic recording medium including: a magnetic recording layer on a substrate; and a protective layer (a) on the magnetic recording layer, wherein the protective layer (a) contains an aniline coloring material. The magnetic recording medium is advantageous in that the magnetic stripe is jet-black and has excellent design properties, and therefore can be widely used for credit cards, bank cards and the like.
