Description

Verfahren zum Herstellen von schallplattenförmigen Magnetogrammträgern Es sind Magnetogrammträger bekannt, bei denen ein paramagnetisches Pulver auf die Gesamtoberfläche einer aus unmagnetischem Werkstoff bestehenden Unterlage in gleichmäßiger Schichtdicke und Dichte aufgetragen wird. Ferner sind Magnetogrammträger in Schallplatteuform mit Führungsrillen bekannt, die aus einem nichtmagnetisierbaren Träger mit magnetisierbarer Auflage bestehen. Als Ausgangsstoff für bandförmige Magnetogrammträger ist ;eine Mischung von magnetisierbarem Pulver mit einer nichtmagn:etisierbaren filmbildenden Masse bekannt. Die Herstellung derartiger Magnenogrammträger bringt technische Schwierigkeiten mit sich, die das Herstellungsverfahren verteuern.Process for the production of record-shaped magnetogram carriers There are known magnetogram carriers in which a paramagnetic powder on the Total surface of a base made of non-magnetic material in a more uniform Layer thickness and density is applied. Furthermore, magnetogram carriers are in the form of a record known with guide grooves that consist of a non-magnetizable carrier with magnetizable Edition exist. The starting material for tape-shaped magnetogram carriers is; a Mixture of magnetizable powder with a non-magnetizable film-forming powder Mass known. The production of such magnenogram carriers brings technical difficulties with them, which make the manufacturing process more expensive.

Vorliegende Erfindung betrifft die Herstellung von schallplattenförmigen Magnetogrammträgern mit Führungsrillen und besteht darin, daß die Platten aus einem für Magnetogrammträger bekannten Gemisch von permanent magnetisierbarem Pulver mit einer nichtmagnetisierbaren filmbildenden Masse unter gleichzeitigem `Eindrücken von Führungsrillen ,oder Aufbringen von nichtmagnetisi@erbaren Führungsdämmen gepreßt werden.The present invention relates to the production of record-shaped Magnetogram carriers with guide grooves and consists in the fact that the plates consist of one mixture of permanently magnetizable powder with known for magnetogram carriers a non-magnetizable film-forming mass with simultaneous pressing of guide grooves, or the application of non-magnetizable guide dams will.

Die Herstellung dieser Magnetogrammträger erfolgt in der Weise, daß unter Anwendung des für Schallplatten allgemein bekannten Preßverfahrens aus der für Magnetogrammträger bekannten Masse ein Magnetogrammträger in Schallplattenform mit Führungsrillen erzeugt wird. Es entsteht somit auf einfache Weise ein handlicher und leistungsfähiger Magnetogrammträger, der die Vorteile der Schallplattenform, der bekannten einfachen Preßverfahren und des bekannten Ausgangsstoffes miteinander vereinigt.These magnetogram carriers are manufactured in such a way that using the pressing process generally known for records from the for magnetogram carrier known mass a magnetogram carrier in the form of a record is generated with guide grooves. A handy one is thus created in a simple manner and powerful magnetogram carrier, which takes advantage of the record shape, the known simple pressing process and the known starting material with one another united.

Beim Pressen des Magnetogrammträgers können die Führungsmittel ein- oder beidseitig vorgesehen werden.When pressing the magnetogram carrier, the guide means can or provided on both sides.
