A magnetic head assembly for recording and playing back information on a recording medium in a vertically magnetized mode. Main and auxiliary heads are provided opposite one another with the recording medium passing therebetween. The main head includes a core of material exhibiting a magnetoresistance effect to which core are attached leads which carry the output play back signal. The auxiliary head has a magnetic core around which is wrapped a winding carrying the recording current. The recorded information patterns have their primary magnetic field components perpendicular to the surface of the recording medium.
