ABSTRACT:
In a magneto-optical recording and reproducing apparatus, a magnetic field is applied to a laser source in the direction of extension of the optical axis of the laser source to radiate a circularly polarized light beam. A magneto-optical disk has a quantum well structure and records information on the disk with the circularly polarized light beam in a magneto-optical manner.
