Abstract
A method, apparatus and program storage device for sensing increased resistance changes in an MR element to detect MR sensor events. The initial MR resistance for each slider is recorded during the drive build. The MR resistance is periodically monitored at later stages of the drive build and during normal operation. The later MR sensor resistance measurements are compared to the baseline measurement taken during the drive build to determine if an MR sensor event occurs, such as contact being made between the MR sensor and the recording medium or an MR sensor being positioned ON or OFF the ramp.
