FLOATING TYPE MAGNETO-OPTIC DISK READING HEAD SYSTEM HAVING EXTERNAL SEMICONDUCTOR LASER RESONATOR OPERATING AT ORTHOGONAL TWO MODE OSCILLATIONS ABSTRACT OF THE DISCLOSURE A magneto-optic disk reading head system including an external semiconductor laser resonator (2, 8, 7, 9, 10). A magneto-optic disk (7) forms a part of the external resonator. In the external resonator, orthogonal two mode oscillations are established to produce a beat signal used for reading data stored in the magneto-optic disk. The magneto-optic disk reading head system is a floating type reading head.
