Abstract
A transducer for writing data on a magnetic carrier includes a magnetic circuit having a writing pole piece (PPI.sub.2), realized in thin magnetic layers of anisotropic magnetic material. A conductor (CMPI) for controlling the writing is coupled magnetically with the pole piece and acts upon the pole piece for writing a datum by reversing the magnetization. A second control is magnetically coupled with the pole piece (PPI.sub.2), but does not act upon the pole piece except in the case of non-writing by diminishing the effective action of the conductor control.
