Recording and/or reproducing apparatus for using magneto-optical disc

A magneto-optical disc recording and reproducing apparatus comprising:

• (a) an optical head for recording signals on a magneto-optical disc and reproducing signals from the magneto-optical disc;
• (b) external magnetic field generating means for supplying an external magnetic field to the magneto-optical disc whereby signals are recorded on the magneto-optical disc by the external magnetic field generating means and the optical head, the external magnetic field generating means being arranged on one side of the magneto-optical disc which is opposite to the optical head and wherein the external magnetic field generating means is positioned coaxially with respect to the optical head;
• (c) spacer means for generating a distance between the magneto-optical disc and the external magnetic field generating means, the spacer means being provided on a surface of the one side of the magneto-optical disc, the spacer means being contacted by the external magnetic field generating means;
• (d) wherein the external magnetic field generating means is movable and is positioned at a first position which is distant from the magneto-optical disc and the spacer means when the optical head is reproducing signals from the magneto-optical disc and at a second position at which the external magnetic field generating means comes in contact with the magneto-optical disc via the spacer means when signals are being recorded on the magneto-optical disc;
• (e) an arm member for supporting the external magnetic field generating means, the arm member being movable between the first position and the second position;
• and
• (f) moving means for moving the arm member between the first position and the second position and keeping the external magnetic field generating means distant from the magneto-optical disc and the spacer means when the signals recorded on the magneto-optical disc are reproduced.
