摘要： The present invention provides a method for the creation and removal of shunts for the prevention of ESD/EOS damage to electrical components. In one embodiment of the present invention, the conductive pathway is provided and removed by exposing the interconnect's carbonizable and ablatable substrate to a radiant energy source such as a laser beam. The present invention also provides for interconnects that include at least two conductive wires or leads engaged on at least one surface by a carbonizable and ablatable material. The conductive wires may each include a branched dead end lead portion interleaved with the branched dead end lead portion of the other. Alternatively, the conductive wires may extend in close proximity to each other in a curved or sinuous or serpentine or backtracking pattern. An interconnect in accord with the present invention may include a substrate substantially supporting the conductive wires except at predetermined locations or proposed shunt sites wherein there is at least one through hole in the substrate.

摘要： In a head protection mechanism (50) for protecting a magnetic head (31) so that a coupled portion of a reader tape (71) is not in contact with the magnetic head, a protection arm (51) is rotatably mounted on a main surface of a chassis (12) close to an actuator assembly (20). The protection arm has a tape passing groove (51a) and an arm portion (514). Rotatably mounted on a back surface of the chassis, a protection lever (54) has one end (541) which is close to a ring cam (62) and which is engageably disposed to a cam face (621). The protection lever has another end (542) which is coupled to a tip (514a) of the arm portion in the protection arm via a hole (12c) bored in the chassis. A spring (53) always urges the protection arm nearer to the actuator assembly.

摘要： A multiple head arrangement for recording and reproducing magnetic information on a magnetic recording medium. The head structure includes an I core body and two core half bodies. A first glass member is interposed between the I core body and the first core half body at a position laterally adjacent a first read/write gap and a second glass member is interposed between the I core body and the second core half body at a position laterally adjacent a second read/write gap. A non-magnetic thin film insulation layer is interposed between the first and second core half bodies and substantially perpendicularly with respect to the read/write gaps.

摘要： An extrusion billet is fabricated from layers of soft magnetic material separated by one or more metal layers. The billet is coreduced and heat treated to impart the desired magnetic properties to the soft magnetic material and also to form intermetallic insulating layers between the magnetic layers. Electric field shield sections are formed in a similar manner by placing relatively thick layers of copper between adjacent layers of metal located adjacent to the layers of soft magnetic material. The layers of soft magnetic metal can also be separated by a layer of semiconductor material; or a metal foil having a semiconductor-forming or high electrical resistivity forming material deposited thereon. In the latter case no extrusion is required. Instead, pressure and heat cause the materials to react and form either a semiconductor layer or a layer with an electrical resistivity higher than about 10.sup..sup.-4 ohm-cm between adjacent layers of soft magnetic metal. Even the deposition step is eliminated by separating and bonding the layers of soft magnetic metal with glass so long as the glass and soft magnetic metal have similar coefficients of thermal expansion.

摘要： The present embodiments relate to a PMR write head with a trailing shield that comprises a FeCoNiM composition. The FeCoNiM composition can be formed via an electroplating process by adding Fe2+, Co2+, Ni2+ and a transition metal salt to an aqueous solution comprised of other additives in an electroplating cell that has an Ni or Co as the anode. The plated HD magnetic material as the trailing shield in a PMR writer can minimize a wide area track erasure (WATE). Further, a high moment high damping shield can lower bit error rate (BER) and increase aerial density capability (ADC) of the write head.
