Claims
- 1. A magnetic-field generator for use in a magneto-optical disk unit comprising:
- a sliding part configured to slide above and spaced from a surface of a loaded magneto-optical disk in a floating manner using an aerodynamic effect; and
- a magnetic-field generating part for providing a magnetic field to the magneto-optical disk, said magnetic-field generating part having a magnetic pole disposed on a side of said sliding part such that said magnetic pole and said sliding a part are positioned adjacent each other in a radial direction of the surface of the loaded magneto-optical disk and said magnetic pole is located closer to a periphery of the loaded magneto-optical disk than said sliding part, wherein an entire flat end surface of said magnetic pole confronting the surface of the loaded magneto-optical disk is generally parallel to and recedes from a slide surface of said sliding part confronting the surface of the loaded magneto-optical disk by a predetermined distance such that said entire flat end surface is spaced further from the surface of the loaded magneto-optical disk than said slide surface.
- 2. A magnetic-field generator as claimed in claim 1, wherein said predetermined distance is sufficient to prevent said magnetic pole from contacting a protuberance existing along an outer rim of an overcoat of the loaded magneto-optical disk while said sliding part is sliding above the surface of the loaded magneto-optical disk.
- 3. A magnetic-field generator as claimed in claim 2, wherein said predetermined distance is in the range of 50-100 .mu.m.
- 4. A magnetic-field generator for use in a magneto-optical disk unit, comprising:
- a sliding part configured to slide above and spaced from a surface of a loaded magneto-optical disk in a floating manner using an aerodynamic effect; and
- a magnetic-field generating part for providing a magnetic field to the magneto-optical disk, said magnetic-field generating part having a magnetic pole disposed on a side of said sliding part such that said magnetic pole and said sliding part are positioned adjacent each other in a radial direction of the surface of the loaded magneto-optical disk and said magnetic pole is located closer to a periphery of the loaded magneto-optical disk than said sliding part, wherein an entire end surface of said magnetic pole confronting the surface of the loaded magneto-optical disk recedes from a slide surface of said sliding part confronting the surface of the loaded magneto-optical disk by a predetermined distance in the range of 50-100 .mu.m such that said entire end surface is spaced further from the surface of the loaded magneto-optical disk than said slide surface.
