摘要： A magneto-optical recording and reproducing apparatus for recording a recording data on a magneto-optical disk through magnetic field modulation is provided with a magnetic head device for applying a recording magnetic field corresponding to a recording signal current onto the magneto-optical disk. The magnetic head means is composed of coil support means including a hollow tubular portion, coil means provided outside the hollow tubular portion of the coil support means, magnetic head means, provided within the hollow tubular portion of the coil support means so as to be capable of freely sliding, for generating the recording magnetic field by supplying the recording signal current into the coil means, and elastic support means for supporting the magnetic head means so as to place it in a stand-by position where the magnetic head means and the magneto-optical disk do not interfere with one another by a push-up force exerted on the magnetic head means in the direction moving away from the magneto-optical disk. The magnetic head means is moved toward the magneto-optical disk in a direction opposite to the push-up force exerted by the elastic support means so as to come in contact with the magneto-optical disk using an electromagnetic force generated by supplying the recording signal current into the coil means.
