Abstract
In a magnetic recording system, a loop-back test circuit provides a technique to test a magnetic recording head, a read circuit, and a write circuit to a read-write head, is sensed through the voltage generated at the head by the test current, such that a small voltage portion of the test signal is transferred through a resistor toga read circuit. The voltage portion is then filtered through a capacitor to form detectable peaks such that the read signal is generated with pulses corresponding to the peaks.
