A magnetic recording medium 10 comprises a first magnetic film 2 and a second magnetic film 4 on a substrate 1. The first magnetic film is composed of a magnetic material preferred for recording and reproduction, and the second magnetic film is composed of a ferrimagnetic material excellent in thermal stability. Information is recorded in the second magnetic film by using a magnetic head 53. After recording the information in the second magnetic film, the first magnetic film is heated by being irradiated with a laser beam to lower the coercivity, and the information in the second magnetic film is magnetically transferred to the first magnetic film. The recorded information is stabilized, because the first magnetic film is excellent in thermal stability. The magnetic recording medium as described above is highly resistant to thermal fluctuation, and it has high reliability. In particular, a magnetic domain of about 0.1 mum, which is formed by magnetic recording at a super high density of 50 Gb/inch<2>, is successfully allowed to exist in a stable manner.
