Date May 22, 1997A magnetic recording medium comprising a smooth recording layer constituted of magnetic particles having a small size, which has a high coercive force. The magnetic recording medium comprises a substrate body, a Cr undercoat with an oxygen content of 100 wt ppm or less, and ferromagnetic metal made of CoCrTa having an oxygen content of 100 wt ppm or less, and which utilizes magnetic inversion. The ferromagnetic metal layer comprises 14 to 23 atm % chromium(Cr), 2 to 8 atom % tantalum(Ta) and the balance of cobalt(Co).
