Previous circuits used to detect faults in magnetic recording write driver and write head circuitry were unable to isolate the fault to the driver or head. The circuit described here in connection with Figs. 1 and 2 is capable of isolating such faults. Moreover, the required bandwidth of the checking circuit is significantly reduced below previous circuit requirements.
