PROBLEM TO BE SOLVED: To improve sufficiently a reproducing output, that is, S/N (C/N) even when problems about restriction of recording density prescribed from conditions at the time of reproduction are dissolved and a recording information bit is made minute. SOLUTION: In a signal reproducing method of a magnetooptical recording medium in which a magnetic film of a magneto-optical recording medium is irradiated with a laser beam LB and recorded information is read out by magneto-optical interaction of a laser beam and a magnetic film in a recording magnetic section, a magneto-optical recording medium having at least a record holding magnetic film and a signal reproducing magnetic film is used, by irradiating this magnetic film with a laser beam, a magnetic section state is changed in the signal reproducing magnetic film, and recorded information is read out making it as power giving temperature in which a magnetic section state is not changed in the record holding magnetic film. |
