Abstract
Screening device for an inscription of information in a groove of an inscription support with a rounded tip adapted to the profile of the groove, characterized in that the scoreboard is composed of at least two partial bodies of different class, each constituting a part of the tip, as a composite body, of which one of them is constituted as a guiding body, of mechanically hard material, non-paramagnetic, preferably diamagnetic and the other is constituted as a magnetic body, for the taking of a magnetic record, composed of material paramagnetic, preferably ferromagnetic.
