ABSTRACT:
In the information reproducing method, the information recording/reproducing method and the information reproducing device of this invention, the start of read of information from a magneto-optical recorded area of an MSR medium is detected, and the power of a light beam to be used for reproducing magneto-optically recorded information is set in accordance with the detection. Thus, the MSR medium can be irradiated with a light beam having an appropriate reproducing power without being affected by the fluctuation in various portions of the MSR medium.
