A compact and light flying head type magneto-optical head apparatus is provided. The magneto-optical head apparatus ( 1 ) of the present invention comprises a suspension ( 12 ) whose one end is fixed to a lower surface of an arm ( 11 ), a slider ( 13 ) fixed to a free end of the suspension ( 12 ), and a magnetic modulation coil ( 14 ) and an object lens ( 15 ) mounted on the slider ( 13 ). The slider ( 13 ) mounted with the magnetic modulation coil ( 14 ) and the object lens ( 15 ) floats due to a wind pressure caused by rotation of an MO disk ( 3 ). The magneto-optical head apparatus ( 1 ) is further provided with a collimeter lens ( 21 ) between a light source ( 71 ) and the object lens ( 15 ) in a hybrid optical apparatus ( 7 ) provided to the arm ( 11 ), and a position of the collimeter lens ( 21 ) can be adjusted vertically along an optical axis O-O by a collimeter actuator ( 23 ), so that optical conditions between the light source ( 71 ) and the object lens ( 15 ) are improved.
