Classification: G11B

Abstract:
An information reproducing apparatus for reproducing information from a magneto-optical recording medium (1), comprising:a magnetic head (52) provided to alternately apply, to each of domains recorded on said magneto-optical recording medium (1), a magnetic field (10) in a first direction and a magnetic field (11) in a second direction opposite to said first detection; an optical head (40) provided to irradiate said magneto-optical recording medium (1) with a laser beam and generate a detected signal (RF0) according to the reflected beam from said magneto-optical recording medium (1); and a reproduced signal detecting circuit (45) provided to detect, as a reproduced signal (RF), a difference between the detected signal (RF0) from said optical head (40) when said magnetic field (10) in the first direction is applied and the detected signal (RF0) from said optical head (40) when said magnetic field (11) in the second direction is applied.
