Abstract
The invention is directed to transducers for recording on (writing) and playback from (reading) a magnetizable support medium. A single transducer (head) provides both record and playback functions. Recording is carried out using a winding for inducing an external magnetic flux across a gap in the transducer and playback is carried out by sensing an internal leakage flux using a Hall effect magneto-resistive element placed outside of a gap in the head. The magneto-resistive element delivers a substantially linear electrical signal response as a function of the magnetic field applied by relative motion between the transducer gap and the support medium.
