A magneto-optical recording device has a flying head that floats over a magneto-optical disk according to the rotation of the magneto-optical disk. The flying head includes a head slider. A solid lubricant is applied to the bottom surface of the head slider facing the magneto-optical disk. Since the solid lubricant makes the flying head contact with the magneto-optical disk smoothly, the scratching and wear of the magneto-optical disk and the flying head decrease. Therefore, the reliability and the durability of the magneto-optical recording device can improve. Physical protrusions and recessions or holes containing fluorocarbon oil therein may be formed instead of the solid lubricant. In this case, the contact area between the flying head and the magneto-optical disk is also smaller than the case where physical protrusions and recessions are not formed. In addition, with a configuration such that thin-film layers made of a fluorocarbon resin having an excellent lubricity are formed on both sides of the bottom surface of the head slider, since the magneto-optical disk comes into contact with the head smoothly, the reliability and the durability of the magneto-optical recording device can improve.
