Abstract

A magnetic thin-layer head with a stratified build-up on a nonmagnetic substrate for a recording medium which can be magnetized perpendicularly (vertically), comprises a ring-head-like magnetic conduction body for carrying the magnetic flux. The conduction body has two magnet legs, of which the poles facing the recording medium are arranged in tandem as seen in the direction of motion of the head and having a predetermined spacing from each other. An at least largely flat read/write coil winding is provided, the turns of which extend through a space formed between the magnet legs. In this magnetic head, a switchable write/read function with a sufficiently large read voltage is obtainable. In addition to the write/read coil winding, a further coil winding is provided only for executing the write function, the turns of which are at least in part arranged in a region outside of the ring-head-like conduction body. In particular, the magnet leg located on the side of the magnetic head facing away from the substrate may be selected by means of predermined current flow directions in the write/read coil winding and the further write coil winding as the recording magnet leg.
