<p>A 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 base, a Cr undercoat with an oxygen content of 100 wt.ppm or less, and a ferromagnetic metal layer 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 atm% tantalum (Ta) and the balance of cobalt (Co).</p> |
