摘要：
A reference current (ICAL) and resistance is used to determine a reference voltage. A variable current is then applied to the MR read head, and is adjusted to produce a voltage equal to that of the reference voltage (V ref). Then, the known current and voltage is used to determine the resistance of the MR read head.
