    摘要: An electrical lap guide (ELG) and a method of using the same to control the machining of a surface of a magnetic transducer to obtain a desired transducer height are disclosed. The transducer and ELG are fabricated in a deposition of layers on a substrate. The ELG includes a first resistor aligned with the transducer such that a machined height of the first resistor is indicative of a machined height of the transducer. Resistances of second and third resistors of the ELG are measured. A sheet resistance of the deposition of layers and a quantity of wafer processing edge movement are determined as functions of the measured resistances of the second and third resistors. An expected non-machined resistance of the first resistor is determined as a function of the determined sheet resistance and as a function of the determined quantity of edge movement. A non-machined resistance of the first resistor is measured. The expected non-machined resistance of the first resistor is compared to the measured non-machined resistance of the first resistor to determine an amount of error.

    摘要: An electrical lap guide (ELG) for use in lapping a bar of magnetic transducer carrying sliders to a desired height is disclosed. A first lapped or analog ELG element is positioned in a first dice lane on the bar between first and second sliders. A first electrical connection is positioned on a surface of the first dice lane for coupling the first ELG element to external circuitry. A second reference ELG element is positioned in the first slider at a position recessed from the lapped surface. A second electrical connection is positioned on the first slider for coupling the second ELG element to external circuitry.

    摘要: An electrical lap guide (ELG) system and method are disclosed for use in lapping a bar 10 of magnetic transducer carrying sliders to a desired transducer height. A first ELG ELG1 contained within the bar has at least two first ELG resistive elements R.sub.11 and R.sub.12. A second ELG ELG 2 contained within the bar has at least two second ELG resistive elements R.sub.21 and R.sub.23. A first of the at least two first ELG resistive elements is electrically coupled to a first of the at least two second ELG resistive elements to thereby reduce a total number of leads needed between a data acquisition unit 100 and the bar 10 during lapping. The reduction in required data acquisition unit 100 leads allow more ELGs to be included on each bar 10 in order to more accurately control the lapping process.

    摘要: A servo head in a disk file data storage system includes at least one shield which acts to block radiation emanating from a nearby data head and thus reduce noise induced in the servo head. The shield is located on either side of an essentially flat conducting coil in a servo transducer, or a data transducer or both. The shield may be either a single layer of material or multiple layers.

    摘要: A servo head in a disc file data storage system includes a servo transducer and a coil which are connected so that noise induced by a nearby writing data head cancels. The servo transducer, mounted on a slider, reads information stored on a servo disc. The coil, also mounted on the slider, is connected to the servo transducer to produce an output signal so that noise signals induced in the servo transducer by operation of the data head tend to be canceled by noise signals induced in the coil by operation of the data head.

    摘要: A head with a heating element and control regime therefor is disclosed. In embodiments described, the control regime or controller energizes the heater or heating element to provide intermittent heating between read or write operations to optimize transducer temperature and operating characteristics or parameters of a data storage device. In particular, in one embodiment described, the controller provides a low amplitude signal or current to provide low grade thermal heating. In another embodiment, the controller provides a high amplitude signal or current to preheat the transducer portion for write operations.
