Slider with integrated writer and semiconductor heterostucture read sensor

Abstract

A slider for magnetic data recording having a semiconductor based magnetoresistive sensor such as a Lorentz magnetoresistive sensor formed on an air bearing surface of the slider body. The slider is constructed of Si, which advantageously provides a needed physical robustness as well being compatible with the construction of a semiconductor based sensor thereon. A series of transition layers are provided between the surface of the Si slider body and the semiconductor based magnetoresistive sensor in order to provide a necessary grain structure for proper functioning of the sensor. The series of transition layers can be constructed of layers of SiGe each having a unique concentration of Ge.
