CALIBRATING READ SENSORS OF ELECTROMAGNETIC READ-WRITE HEADS

摘要

Described are embodiments to calibrate read sensors, which in turn may ensure that the equipment utilized to detect antigens is reliable and accurate. If it is determined that a read sensor is degraded a method of calibrating a read sensor of a read head may be used.

1. A method of calibrating a magnetic read sensor, the method comprising:
measuring a first resistance of said magnetic read sensor upon an application of a forward bias current to said magnetic read sensor; measuring a second resistance of said magnetic read sensor upon an application of a reverse bias current to said magnetic read sensor; determining, using a hardware processor, a calibration constant based on at least said first measured resistance, said second measured resistance, and a magnitude of at least one of the applied bias currents; storing said determined calibration constant for said magnetic read sensor in memory; and adjusting a read response from said magnetic read sensor based on said determined calibration constant.
