Magnetic-field generator for use in a magneto-optical disk unit
摘要
A sliding part of a magnetic-field generator is configured to slide above and spaced from a surface of a loaded magneto-optical disk in a floating manner. A magnetic-field generating part, which provides a magnetic field to the magneto-optical disk, includes a magnetic pole disposed on a side of the sliding part such that the magnetic pole and the sliding part are positioned adjacent to each other in a radial direction of the surface of the loaded magneto-optical disk and such that the magnetic pole is located closer to a periphery of the magneto-optical disk than the sliding part. An entire flat end surface of the magnetic pole confronting the surface of the magneto-optical disk is generally parallel to and recedes from a slide surface of the sliding part such that the entire flat end surface is spaced further from the surface of the magneto-optical disk than the slide surface of the sliding part.
