Abstract

A device for reducing and, in a given case, avoiding the mutual influence of two magnetic heads, in particular of two magnetic heads attached to a multiple magnetic head for recording and/or reproducing one or more parallel registers on a record carrier, provided of a magnetizable material, the heads of which have been arranged one after the other in the direction of movement of the carrier and each comprises at least two parts of a ferromagnetic material, particularly a ferromagnetic, oxidic and sintered material with a useful range remaining between two parts mentioned, filled with a non-magnetizable material, which ensures the two aforementioned parts between themselves, while, between the magnetic circuits including the interval, at least one plate of a non-magnetizable, electrically conductive material is provided, characterized because in line with said plate on the back side of the carrier, as close as possible therein, a plate of a non-magnetizable material, good electrically conductive, is arranged.
