Abstract

A servosystem for controlling the position of a magnetic head with respect to the tracks of a magnetic recording medium which is relatively movable with respect to the head and has a plurality of juxtaposed tracks, including a read head for simultaneously reading information signals and servosignals stored in the tracks, the read head having a head face and a layer structure comprising parallel read units, each having a read gap and extending substantially transversely to the head face, the read gaps of two adjacent read units each extending between a magnetically conducting common pole terminating in the head face and an individual pole terminating in the head face.
