摘要： A transducer head assembly used in a read/write recording apparatus employs an air bearing that supports a carriage on an air cushion for reciprocal motion. The carriage supports a transducer and is moved by a drive in order to read or write on a track located on a storage tape. The bearing and the carriage may be mutually keyed to prevent relative rotation. The air bearing is shown to be a porous ceramic material such as alumina. The bearing may be triangular in cross-section, and the carriage may be a triangular frame telescopically received on the bearing. The drive may be a conductive coil that interacts with a magnet on the carriage. A dual air bearing and dual carriages is disclosed to support a pair of transducers. A method of supporting and moving a transducer implements the steps of this structure.

摘要： 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.

摘要： An optical servo magnetic head in which the rigidity in a slider is maintained, and a servo error due to dust particles is suppressed. In a separate type magnetic head (1) generally composed of a slider (2) and a back yoke (3), the slider (2) is provided with magnetic cores (11 and 12) for standard recording density and high recording density, respectively, in order to cover, with a single unit of magnetic head, a plurality of recording media having respective recording densities different from each other. A laser beam is used to guide the magnetic head to a prescribed track position, and passage-holes (5 and 6) for permitting the laser beam to pass through are formed through the slider (2) and the back yoke (3), respectively, by molding or machining. Since the passage-holes (5 and 6) can be respectively set to a minimal size required for permitting the laser beam to pass through, it is possible to maintain rigidity in the slider (2) and prevent fine dust particles generated due to the sliding between the recording medium and a sliding surface of the magnetic head from falling through the passage-holes.

摘要： A near-field optical system having one or more solid state lasers and an aerodynamically shaped slider which comprise a single integrated, monolithic device fabricated from the same base semiconductor material. The monolithic optical head can be quickly and easily attached to the read arm of an optical read/write device without requiring attachment of separate laser elements, and without micropositioning or use of optical microscopy for positioning the lasers. The optical head comprising a single semiconductor substrate including a first region which defines a slider having an air bearing surface, and at least one second, laser region which defines a diode laser, with the diode laser having an emission face which is substantially co-planar with the air bearing surface. The semiconductor substrate preferably includes an active layer, a p-clad layer or reflective layer adjacent a first side of the active region, an n-clad layer or reflective layer adjacent a second side of the active layer, and an n-semiconductor layer adjacent the n-clad layer. A slider region of the semiconductor substrate includes an air bearing surface, adjacent the p-clad layer, which is aerodynamically structured and configured to define a slider. The integral lasers include a p-electrical contact adjacent to the p-clad layer and proximate to the laser emission face, and an n-electrical contact adjacent to the n-clad layer or an n-semiconductor layer. The laser mode is defined by oxidized or ion-diffusion regions associated with the p-clad layer or n-clad layer of the laser. A conductive via through the substrate allows electrical connection with the p-side contact to be achieved from the n-side of the substrate. The optical head is used in a near-field optical system with an optical medium having a phase change layer.
