Abstract: @ A winding apparatus has a holding unit (11) on which a video head (1) having a through hole (5) is mounted. Awire (4) is supplied by a wire supply unit (12) through the through hole from one end thereof. A first wire suction unit (125) draws by suction the wire from the other end side of the through hole and is moved away from the video head to render the wire taut. The video head is pivoted 180° by the holding unit so that the wire stretched is wound around the head. Then, a firstwire feeding unit (112) clamps the end portion of the wire at the first suction unit side, and is pivoted 180° and moved to the vicinity of the head to direct the end ofthe wire to the through hole. Thereafter, the first feeding unit feeds the wire through the through hole from one end thereof, and the wire fed is drawn by a second suction unit (126) from the other end side of the through hole. The second suction unit is then moved away from the head to stretch the wire between the head and the second suction unit, thereby winding the wire around the head. The head is then pivoted 180° by the holding unit to wind the wire around the head. Thereafter, a second wire feeding unit (113) clamps the end portion of the wire at the second suction unit side, and is pivoted 180° and moved to the vicinity of the head to direct the end ofthe wire to the through hole. The second feeding unit then feeds the wire through the through hole. Thereafter, the first and second suction units, the first and second feeding units, and the holding unit are continually driven in the above steps.

Abstract: A flux enhanced data transducer (40) and method for producing the same in conjunction with shared shields on MR read heads in which substantially between 500-2500 ANGSTROM of a relatively higher magnetic moment material (48) is added to the upper surface of the shared shield (42), or bottom write head pole, prior to a magnetic flux containment ion milling operation utilizing the upper pole (44) as a mask. The relatively higher magnetic moment flux enhancement layer may comprise CoNiFe, FeN or similar material which is deposited prior to the formation of the dielectric gap layer (46). The flux enhancement layer may then be selectively removed substantially surrounding the upper pole by means of a relatively brief ion milling process in which only on the order of 1.0 k ANGSTROM of the layer need be removed and during which only an insignificant amount of the material removed might be re-deposited on the sides of the upper pole.

These slots (18, 19) provide an air bleed in the air bearing surface of the rails (14, 15). The air bleed capacity of the slots (18, 19), the width of the rails (14, 15) and the load force applied by the flexures (20) provide optimal width of the rails (14, 15) for stabilizing the media (13) while maintaining a low fly height of the electro-magnetic elements (16, 17) on the media (13).

Abstract: An unshielded horizontal magnetoresistive head (1) for magnetic sensing and reading devices. The horizontal unshielded magnetoristive head (1) is comprised of two magnetoresistive elements (2) separated by a gap (10), and a conductive cross member (3) which electrically connects the magnetoresistive elements (2) together and to a common electrical point such as system ground (4). A differential voltage sensing circuit (35) is connected across the magnetoristive elements (2) for sensing voltage variations when magnetic data is sensed by the head (1). The present invention further facilitates a more simplified fabrication process which results in cost savings and more efficient fabrication methods and procedures.

Abstract: The pole includes at least two ferromagnetic layers (22, 24) having different uniaxial anisotropies and a nonmagnetic layer (26) disposed between the ferromagnetic layers. The nonmagnetic layer inhibits exchange coupling between the magnetic layers so as to eliminate edge domains. Magnetic flux is conducted by rotation which can occur at high frequencies and which does not generate any magnetic noise. If the nonmagnetic layer is an electrical insulator, eddy currents are also suppressed. Embodiments are disclosed in which the nonmagnetic layer completely separates and partially separates the ferromagnetic layers.
