METHOD AND APPARATUS FOR READING RECORDED DATA BY A MAGNETORESISTIVE HEAD

METHOD AND APPARATUS FOR READING RECORDED DATA BY A MAGNETORESISTIVE HEAD

Method and apparatus for magnetoresistive (MR) head biasing and output signal detection for reading data recorded in magnetic media. The MR head may be biased by constant current or constant voltage, and an output signal, proportional to the ratio of the instantaneous value of the change in MR head...

description Method and apparatus for magnetoresistive (MR) head biasing and output signal detection for reading data recorded in magnetic media. The MR head may be biased by constant current or constant voltage, and an output signal, proportional to the ratio of the instantaneous value of the change in MR head resistance to total MR head resistance when exposed to the magnetic field of the media, is detected.
