ABSTRACT:
A current driver for magnetic recording comprising a current source, a current steering bridge for directing the current in one of two directions through a magnetic recording head during the length of a data pulse and a head select switch which allows current to flow through the head only for several short pulses occurring during the data pulse such that the magnetic regions impressed by the short pulses form a nearly continuous magnetic region on the recording medium.
