構。 A magneto-optical drive device in which a magnetic head and an optical head are opposed to each other via a magneto-optical disk and both heads are reciprocated integrally in the radial direction of the disk, which has a magnetic head support arm and is movable up and down relative to the disk surface. At the same time, a support column with rollers attached above is fitted to the optical head so as to be movable up and down, and a rail supported by an elastic member is provided in a space on the side of the magnetic head of the apparatus main body, and the rail is pushed against the elastic member. A solenoid is provided to separate the rail from the disk surface side, and the rail and the roller are installed so that they are guided and rolled by mutually inclined tapered surfaces. By energizing the solenoid when loading or seeking the disk, the rail is moved in the direction of the disk surface. 1. A magnetic head lift-up mechanism for a magneto-optical drive device, characterized in that the magnetic head is lifted up by separating the column from the magnetic head and also separating a column to which a roller is attached.
