Magneto-optical head and magneto-optical recording apparatus including same
InactiveUS20020097639A1Avoid thermal expansionAppropriately maintain optical characteristicOptical head protectionOptical flying-type headsOptical propertyEngineering
A magneto-optical recording head comprises a magnetic coil formed on a lower surface of a transparent substrate opposed to a magneto-optical disk. A heat sink layer is provided at the outside of the magnetic coil on the lower surface. An objective lens is supported on an upper surface of the transparent substrate. The heat, which is generated by the magnetic coil, is released via the heat sink layer to the space between the magneto-optical disk and the substrate. The release of the heat is facilitated by the air stream which is generated by the rotation of the magneto-optical disk. The heat can be effectively released from the magnetic coil without inhibiting optical characteristics of the objective lens.

A hydraulic bearing that supports a rotating shaft comprises a bearing metal. On a surface of the bearing metal, a hydrostatic pocket and a land portion are formed. The land portion is defined by the hydrostatic pocket and generates hydrodynamic pressure in response to a rotation of the rotating shaft. The hydraulic bearing further comprises a pressure fluid supplying source and an oil-supplying hole. The oil-supplying hole is opened in the hydrostatic pocket and provides pressure fluid from the pressure fluid supplying source to the hydrostatic pocket. On the land portion, a drain hole that drains the fluid is formed. On the way of a drain passage, a check valve is disposed. Since the drain hole does not separate the land portion, deterioration of bearing rigidity is restrained. Further, since the fluid is drained through the drain hole, thermal expansion of the bearing metal due to heat generation of the fluid is restrained. Moreover, according to the check valve, it is possible to prevent suctioning air into the hydraulic bearing when negative pressure generates at the land portion.
