UNSHIELDED MAGNETORESISTIVE HEAD WITH MULTIPLE PAIRS OF SENSING ELEMENTS

摘要

A new and improved unshielded horizontal magnetoresistive head (100) is disclosed which utilizes multiple pairs of magnetoresistive elements (1, 2, 3, 4). The present invention provides a device which is characterized by reduced output signal undershoot amplitudes, and an increased central peak pulse amplitude, while not significantly affecting the resolution of the device. The device is also characterized by increased signal to noise and signal to interference ratios. Magnetoresistive elements (1, 2, 3, 4) utilized in the device may be fabricated and/or manufactured by simplified processes, resulting in fabrication, manufacturing and cost benefits for the magnetoresistive head. Any number of additional magnetoresistive head. Any number of additional magnetoresistive element pairs may be utilized dependent on the accuracy and resolution required by the specific application.
