A magneto-optical recording/reproducing method is disclosed which causes a laser
beam to be emitted to a disc recording medium having information recorded thereon
earlier by magnetic field modulation, the laser beam causing the disc recording
medium to develop a temperature distribution such as to generate a driving force
for moving a domain wall of a magnetic domain in the medium so that the magnetic
domain smaller in diameter than a spot of the laser beam is expanded sufficiently
to let information recorded in the domain be detected. The method comprises the
steps of: recording information to the disc recording medium while rotating the
medium in a first rotating direction; and reproducing the information that was
recorded to the disc recording medium in the recording step while rotating the
medium in a second rotating direction reverse to the first rotating direction.
