摘要： In an Integrated Lead Suspension system, it is desired that the stainless steel suspension is grounded to a controlled ground potential. This requires creating a grounding path between the stainless steel suspension and a copper trace layer through a layer of dielectric material that separates the stainless steel suspension and the copper layer. The copper trace layer and subsequently the stainless steel suspension can then be grounded to a controlled ground potential. This invention proposes several methods of creating a ground path between the stainless steel suspension and the copper trace layer.

摘要： A read/write head cooling system for use in a magnetic storage device, such as, for example, a hard disk drive is provided. In one embodiment, a thermally conducting patterned cold plate is thermally situated between a write coil and a read sensor of the read/write head. A microcooler, such as, for example, a thermoelectric cooler, is thermally coupled to the cold plate. A hot plate of one or more heat dissipation elements, such as, for example, copper posts, is thermally coupled to the hot side of the microcooler. The write coils of the read/write head are actively cooled by the microcooler to reduce the temperature of the write coil and read sensor in the head below that attainable with passive mechanisms.

摘要： A switchable shunt has an insulating layer separating conductive lead and spring metal layers. The shunt includes a base region formed on the spring metal layer, one or more arms formed in the conductive lead layer and at least one of the insulating and spring metal layers, one or more pad regions electrically coupled to an arm and formed in at least the conductive lead layer, and one or more gaps. Each arm extends through a gap and is resiliently biased toward a shunted state with the pad region in electrical contact with the base region. The shunt is movable to an electrically open state where the pad and base regions are electrically isolated. A method of making the shunt includes etching the shunt from laminated material and pushing the arm and pad through the gap. The shunt may be operated by applying a force to the arm.

摘要： A first read gap layer has a resistance RG1 between a first shield layer and one of the first and second lead layers of a read head and the second read gap layer has a resistance RG2 between a second shield layer and said one of the first and second lead layers of the read head. A connection is provided via a plurality of resistors between a first node and each of the first and second shield layers wherein the plurality of resistors includes at least first and second resistors RS1 and RS2 and the first node is connected to said one of the first and second lead layers. A second node is located between the first and second resistors RS1 and RS2. An operational amplifier has first and second inputs connected to the first and second nodes respectively so as to be across the first resistor RS1 and has an output connected to the first node for maintaining the first and second nodes at a common voltage potential. In a first embodiment the first and second shield layers are shorted together. A test instrument is then employed for determining the combined parallel resistance of the resistors RS1 and RS2 by having a first side of the test instrument connected to the first node and the second side connected to each of the first and second shield layers. In the second embodiment a third resistor RS3 is connected between the second node and one of the shield layers, such as the second shield layer. The test instrument can determine the resistances of the first and second gap layers separately by being connected between the first node and the first shield layer for the resistance of the first gap layer or between the first node and the second shield layer for the resistance of the second gap layer.

摘要： This invention discloses a circuit including a magnetoresistive sensor and a tunnel junction device coupled to the MR sensor to dissipate the energy associated with an electrical signal exceeding operational voltages for the sensor. The tunnel junction can include a first conducting layer, a second conducting layer, and a barrier material positioned between the first and the second conducting layer. The barrier material can be positioned so that the first conducting layer and the second conducting layer do not make contact. The MR sensor can be connected in parallel to the first and second conducting layer. The tunnel junction can be made of a material with a resistance more than the MR sensor's resistance at operational voltages and a resistance below the MR sensor's resistance at larger voltages. In another aspect of the invention, a method for fabricating the protected circuit including integrating a MR sensor on the circuit and coupling a tunnel junction to the MR sensor to dissipate an electrical signal exceeding operational voltages for the MR sensor is presented. The tunnel junction device can be fabricated during the fabrication of the circuit. The method can include fabricating the tunnel junction on the MR sensor.
