A read/write device for a disk drive is disclosed. The read/write device
includes a pre-amplifier and a recording head. The read/write device also
includes a write signal path between the pre-amplifier and the recording
head. The write signal path includes a write current. The read/write
device also includes a read signal path between the pre-amplifier and the
recording head. The read signal path includes an induced current related
to the write current. The read/write device also includes a shunt path in
the pre-amplifier to draw a part of the induced current from the read
signal path.
