发明名称 Magneto-optical recording medium and apparatus.
摘要 <p>Guide parts and driving parts are independently provided for an optical head and a magnetic bias field generator, and a relative position control part controls the relative positions of the two so that the both can access the tracks individually. Furthermore, a magnetic pattern track for use as the detection signal of the absolute position of the magnetic bias field generator to the magneto-optical recording medium is formed on the magneto-optical recording medium itself, and a positioning control part of the magnetic bias field generator using this magnetic pattern track is provided, so that the positioning control of the absolute position of the magnetic bias field generator with respect to the magneto-optical recording medium may be realized.</p>
