The magnetic layer is comprised of a ferromagnetic metal powder and a binder. The ferromagnetic metal powder has a specific surface area of not less than 30 m.sup.2 /g. The magnetic layer is further comprised of a fatty acid and a fatty acid ester in a total amount of 2 to 10 wt % based on the weight of the ferromagnetic metal powder. The proportion of the fatty acid ester is 15 to 60 wt % based on the total weight of the fatty acid and the fatty acid ester. The surface roughness of the magnetic layer is not more than 0.03.mu.. The recording medium has excellent video characteristics obtained by the use of fine metal particles having the disclosed specific surface area and by increasing the surface properties of the magnetic layer so that spacing loss between the recording or reproducing head and the recording tape is decreased and output level is increased and modulation noise is decreased so that the video S/N is increased.
