Abstract

Dans un style comportant un aimant d'écriture permanent, aimanté dans le sens axial et en forme de tige pour inscrire des marques sur un support en forme de feuille présentant des particules magnétiquement orientables pour l'enregistrement et la lecture optique de ces marques, un porte-aimant en forme de tige est prévu et porte, à une extrémité, l'aimant d'écriture. De plus, à l'autre extrémité du porte-aimant, se trouve un aimant d'effacement permanent qui sert pour l'effacement du support, le porte-aimant comportant des moyens de guidage disposes au voisinage de l'aimant d'effacement pour, pendant un déplacement du support par rapport à l'aimant d'effacement ou inversement, maintenir la surface de support du support orientée dans une position à peu près perpendiculaire à une surface d'extrémite polaire de l'aimant d'effacement. Application à l'enregistrement magnétique.In a style comprising a permanent, axially magnetized, rod-shaped writing magnet for inscribing marks on a sheet-like medium having magnetically orientable particles for recording and optical reading of such marks, a rod-shaped magnet holder is provided and carries, at one end, the writing magnet. In addition, at the other end of the magnet holder, there is a permanent erasure magnet which is used for erasing the support, the magnet holder comprising guide means arranged in the vicinity of the erasing magnet for , while moving the medium relative to the erase magnet or vice versa, maintaining the support surface of the oriented medium in a position approximately perpendicular to a pole end surface of the erasing magnet. Application to magnetic recording.
