    摘要: The present invention is a method of using direct head electrical response signals for feedback process control. When lapping the air bearing surface of a bar of sliders, a magnetic field is applied to the air bearing surface and a bias current is applied to the reader elements. A head electrical response, such as amplitude or resistance change, is measured and is used to control the lapping device. Using a fixture which allows individual slider machining, a controller can be used to monitor the head response signal for each slider on the bar and individually control each slider on the bar so that material removal over each slider proceeds until a predetermined target stripe height is reached.

    摘要: A lapping system data acquisition unit is disclosed for use in measuring resistances of multiple resistors embedded in a structure to be machined. Each of multiple independent current sources directs a current through one of the multiple resistors embedded in the structure during machining of a surface of the structure. Each of multiple voltage sensing devices couples to a separate one of the multiple resistors and provides a separate analog voltage output signal indicative of the resistance of the resistor. Each of multiple filters is coupled to a separate one of the multiple voltage sensing devices Analog-to-digital conversion circuitry coupled to the multiple filters generates a digitized signal for each of the filtered output signals.

    摘要: An apparatus and method of machining sliders to obtain the optimum PTR for each slider. An array of MEMS devices configured for angular actuation are provided, and a slider is placed in each MEMS device of the array. The ion milling of the sliders is controlled individually for each slider based on the relationship of the ion angle and relative etch rates of the slider components. The MEMS devices are controlled to ensure the ion incidence angle for each slider is such that the desired PTR of each slider is achieved.

    摘要: A method and system for lapping a magnetic transducer using an electrical lapping guide is presented. This includes rough lapping the transducer based on a first signal and fine lapping the transducer based on a second signal from a dummy transducer. The dummy transducer can have electrical properties substantially similar to electrical properties of the magnetic transducer. The first signal can include a stripe height calculated as a function of a reference resistor element and an analog resistor element. The second signal can include lap to reader resistance from the dummy transducer and a stripe height calculated from a reference resistor element and an analog resistor element. The dummy transducer can also provide process noise monitoring capability during lapping.
