    • PURPOSE: A magnetic transducer having an integrated charge bleed resistor is provided to prevent electrostatic discharge damage against a sensor by reducing the electric charge on the magnetoresistive sensor element of a magnetoresistive head assembly. CONSTITUTION: A magnetoresistive transducer(50) includes a substrate(30); an insulating layer(64); a magnetoresistive assembly having a magnetoresistive element(52) on the insulating layer; and a bleed resistor formed between the magnetoresistive assembly and the substrate. The bleed resistor couples the magnetoresistive assembly to the substrate. The bleed resistor has a relative large electrical resistance and provides a discharge path for accumulated charge. The arrangement effectively prevents electrostatic discharge damage to the sensor.
    • 目的:提供具有集成电荷泄放电阻器的磁换能器,以通过减小磁阻头组件的磁阻传感器元件上的电荷来防止对传感器的静电放电损坏。 构造:磁阻换能器(50)包括衬底(30); 绝缘层(64); 在所述绝缘层上具有磁阻元件(52)的磁阻组件; 以及形成在磁阻组件和衬底之间的渗漏电阻器。 放电电阻将磁阻组件耦合到衬底。 放电电阻具有相对较大的电阻,并提供用于累积电荷的放电路径。 该装置有效地防止传感器的静电放电损坏。
