摘要： Magnetic head for use in magnetic recording and including an integrated coil having at least one winding around a non-embedded part of the magnetic circuit. The winding includes a lower sheet of conductors placed in a chamber etched in the substrate and which is integrated into this substrate. The magnetic head is manufactured in a process including forming on a solid substrate a magnetic circuit with a first and second polar part having embedded portions positioned side by side and separated by a nonmagnetic air gap. The magnetic circuit includes at least one non-embedded bridging part no portion of which is embedded in the substrate. A conductor coil is formed around the non-embedded part of the circuit by making a lower sheet of conductors passing underneath the non-embedded bridging part and by embedding the lower sheet in at least one chamber made in the substrate, and by making an upper sheet of conductors astride the non-embedded bridging part of the magnetic circuit.

摘要： A circuit and method for detecting an abnormality in a recording head, wherein a voltage detection circuit detects a counter electromotive voltage generated across the two terminals of a recording head to which a recording current is supplied from a recording circuit; a processing circuit generates the maximum, minimum, and mean voltages from the counter electromotive voltage; a discrimination circuit using these voltages determines whether an abnormality occurs in the recording head. An output circuit outputs the result. With this operation, an abnormality in the recording head having two terminals in an MR head can be detected with a high precision.

摘要： A floating type of magnetic head having a high mechanical strength and a superior productivity and a method for producing the same are provided. A slider is composed of a first slider body and a second slider body. A main cut groove and a second sub-cut grooves are formed on a bonded surface side of the first slider body so that a first pillar portion and a second pillar portion around which lead lines are to be wound together with a first core body and a second core body a magnetic head core are left. Since the first and second pillar portions are bonded to the second slider body and during the assembling and machining operations, the first and second pillar portions receive a force that is applied to the slider or the magnetic head core to be effective for the reinforcement of the mechanical strength, the slider or the magnetic head may hardly be damaged or broken down. It is possible to facilitate the manufacturing steps in comparison with the case where a reinforcement portion is formed to bridge over a groove for winding a lead line in a single slider. Accordingly, it is possible to enhance the productivity.

摘要： A magneto-resistive read/write tape head is provided for reading and writing to tape media along a tape head face. The tape head comprises a plurality of modules, each module comprising a read element and a write element spaced apart and terminating at the tape head face and formed over a substrate. The read element comprises a soft film bias layer and a hard film bias layer butted against the SFB layer. The write element comprises two pole tips spaced apart by a gap. The tape head further includes a plurality of activating conducting coil turns operatively associated with the write element and covered by a cross-linked photoresist and positioned between the gap and one of the pole tips and set back from the tape head face. The tape head has at least one of the following elements: (a) a wear shield between the read element and the write element for limiting wear of the gap between the two pole tips, the wear shield being grounded for decoupling read and write functions of the tape head, for allowing same module read/servo/write functions simultaneously, and for grounding static charge from the tape media; (b) a layer of electrically conductive and corrosion-resis tant material, such as rhodium, under the hard film bias layer to reduce its resistance; and (c) a non-activating dummy coil turn closer to the pole tips than the activating coil turns for defining a forward termination of the cross-linked photoresist between the activating coil turns and the tape head face to thereby provide improved ease of processability.

摘要： This invention relates to a wiring structure having metal wiring layers and polyimide layers. An object of this invention is to overcome problems caused by oxidation of a metal surface, such as an increase in the resistance of wiring and a reduction in insulation, by preventing a reaction between a metal of the wiring layers, such as copper, and carboxyl groups of polyamic acid which make up the polyimide layers. In the wiring structure according to the present invention, the polyimide layers have been formed by heating and curing a resin composition which comprises a polyimide precursor, an amine compound and an organic solvent.

摘要： A head assembly for use in a VCR includes a head base, a head chip comprised of a first non-magnetic substrate block, a magneto-resistive head, a thin film head, and a second non-magnetic substrate block, an FPCB attached to the magneto-resistive head, and an FPCB attached to the thin film head. Such a head assembly can record or reproduce high density magnetic signals by virtue of the very small magnetic gaps incorporated therein. Such a head assembly can be manufactured by forming the magneto-resistive and thin film heads on a substrate wafer using layering processes. In the alternative, the magneto-resistive head and the thin film head can be formed on separate substrate wafers by using layering processes, and then combined to produce a head chip.

摘要： The present invention is an integral magnetic head suspension and method for making the same. The integral suspension, with or without the head, contains integrated conductive circuits that have multiple cross overs for noise reduction. The suspension is fabricated completely on silicon (Si) wafers using semiconductor processes. A N+ silicon layer is disposed over a P- silicon wafer. The N+ silicon layer and the P- silicon wafer are thermally oxidized to generate a bottom silicon oxide layer opposite the N+ layer side of the wafer and a top silicon oxide layer on the N+ side of the wafer, and to drive the N+ silicon into the P- silicon wafer. A layer of polysilicon is disposed over the silicon oxide layer on top of the N+ silicon layer. One or more pairs of conductive traces having multiple cross-overs are fabricated on the layer of polysilicon. Optimally, a magnetic head is simultaneously fabricated on the suspension. The polysilicon layer is then patterned to define the head structure and suspension structure as one piece. Finally, the magnetic head and suspension are separated from the wafer by removing the first silicon oxide layer by a chemical etchant and the P- silicon wafer by selective etching. The head and suspension are released from the silicon wafer as a single structure using the above-described semiconductor processes. Accordingly, no grinding or cutting is used to define the dimensions of the head. Further, no processes are required to attach the head to the suspension and the suspension can be made from low mass materials such as silicon (Si) or Al.sub.2 O.sub.3.
