Abstract
A preferred embodiment of an electromagnetically controlled scanning magnetic transducer is described having two confronting core poles defining a physical transducing gap therebetween. A control winding is associated with each core pole. A control current applied to each control winding selectively saturates a portion of each core pole facing a record medium. Each saturated face portion defines an adjacent unsaturated highly permeable face portion. The highly permeable face portions of each core pole overlap across the gap to define a transducing zone. The information signal and control windings are arranged relative to one another to obtain information signal and control flux paths extending perpendicular to one another.
