ABSTRACT:
A magnetostrictive record and playback head is disclosed which utilizes an acoustic wave traveling along the surface of piezoelectric material so as to distort the surface thereof and to change the stress in a layer of magnetostrictive material along that surface at a point which depends upon the position of the traveling acoustic wave. At the point where the magnetostrictive material is changed, the material is magnetic so that a pulse in an adjacent conductor will cause a flux to form that can deposit a magnetic signal on adjacent magnetic tape.
