ABSTRACT:
Disclosed are magnetic recording media comprising, on a substrate, two or more CrPt based magnetic layers and one or more CrMo based non-magnetic spacer layers between the magnetic layers and processes for preparation thereof. The magnetic recording media of the present invention include magnetic tapes and magnetic disks. The magnetic recording media are capable of suppressing noise generation upon reproducing recorded signals by employing magnetic layers having a small thickness. The magnetic recorders utilizing the above magnetic recording media are also disclosed.
