发明名称 Information recording medium, information recording apparatus, and recording method
摘要 A magnetic recording medium comprises a first magnetic film and a second magnetic film on a substrate. The second magnetic film is composed of a magnetic material preferred for recording and reproduction, and the first 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. The first magnetic film is heated by being irradiated with a laser beam to lower 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 is highly resistant to thermal fluctuation, and it has high reliability. A magnetic domain of about 0.1 mum, formed by magnetic recording at a super high density of 50 Gb/inch<SUP>2</SUP>, is successfully and stably allowed to exist.
