置。 In a magneto-optical recording and reproducing apparatus that applies an alternating magnetic field as a recording bias magnetic field to a magneto-optical recording medium and modulates and irradiates a light beam corresponding to a recording signal in synchronization with the alternating magnetic field, the light beam is A light beam characterized in that an E/O deflector is disposed in the optical path system, and the modulation signal is used during recording to change the refractive index of the E/O deflector to move the light beam in the track direction. Magnetic recording and reproducing device.
