Description
Magnetkopf für Magnetschichtspeichergeräte (Zusatz zu Anmeldung *?H2Aoi2:y.) Magnetic head for magnetic layer storage devices (addition to registration *? H 2 A o i 2 : y .)
Das Hauptpatent (Anmeldung p.H ?* cft'f) betrifft einen Magnetkopf für Magnetschichtspeichergeräte zur Aufzeichnung digitaler Informationen mit einem aus dünnen miteinander verklebten Folien magnetisierbaren Materials bestehenden Magnetkern, der dadurch gekennzeichnet ist, daß mindestens ein Schenkel des im wesentlichen trapez- oder rechteckförmigen Magnetkerns in der Nähe seines dem Kernspalt entgegengesetzt liegenden Ansatzpunktes eine senkrecht zur Schichtung verlaufende Einkerbung aufweist, die eine wesentliche Verringerung des Kernquerschnitts bewirkt.The main patent (application p . H? * C ft'f) relates to a magnetic head for magnetic layer storage devices for recording digital information with a magnetic core consisting of thin sheets of magnetizable material glued together, which is characterized in that at least one leg of the substantially trapezoidal or Rectangular magnetic core has a notch running perpendicular to the stratification in the vicinity of its starting point opposite the core gap, which causes a substantial reduction in the core cross-section.
Dem Gegenstand des Hauptpatents liegt die Aufgabe zugrunde, eine besondere Ausbildung des Magnetkopfes bzw. seines Kerns anzugeben, die eine wirtschaftliche günstige Herstellung erlaubt.The subject matter of the main patent is based on the task Specify a special design of the magnetic head or its core, which is economical to manufacture permitted.
Diese Forderung wird'durch die im Hauptpatent angegebene Lösung zwar weitgehend erfüllt, doch haftet dieser immer noch der Mangel einer schwierigen Handhabung an, bedingt durch die geringen Abmessungen des Magnetkopfes (ca. 4 auf 5 mm).This requirement is given by the one specified in the main patent Although the solution has largely been fulfilled, this is still due to the lack of difficult handling, conditionally due to the small dimensions of the magnetic head (approx. 4 by 5 mm).
Dementsprechend stellt sich die Aufgabe, die Handhabung VPA 9/210/1026 She/FdIAccordingly, the task of handling VPA 9/210/1026 She / FdI

bei der Herstellung von Magnetköpfen zu erleichtern und damit die Wirtschaftlichkeit des Herstellvorgangs weiter· zu verbessern.to facilitate the production of magnetic heads and thus the profitability of the manufacturing process further to improve.
Semäß einer Weiterbildung der Erfindung wird diese Aufgabe bei einem im übrigen nach dem Vorschlag des Hsuptpatents ausgebildeten Magnetkopf dadurch gelöst, daß an das dem Spalt gegenüberliegende Ende des Magnetkerns ein vorzugsweise die gleiche Schichtung wie der Magnetkern aufweisender Lappen ansehließt, dessen Abmessungen vorzugsweise etwa gleich bis etwa doppelt so groß wie die Außenmaße des Magnetkerns sind und der erst unmittelbar vor der Fertigstellung des Magnetkopfs bzw." nach dem Einbau in seine Halterung abgetrennt wird ·According to a further development of the invention, this object is achieved with one moreover according to the proposal of the main patent formed magnetic head solved in that at the end of the magnetic core opposite the gap, a preferably the same layering as the tabs having the magnetic core, the dimensions of which are preferably approximately the same up to about twice as large as the external dimensions of the magnetic core and which is only just before the completion of the Magnetic head or "separated after installation in its holder will ·
Die Figur zeigt als Ausführungsbeispiel die Seitenansicht eines Kerns für einen Doppelmagnetkopf mit dem erfindungsgemäß angesetzten Lappen 1. Der Kern hat die beiden Spalte 2 und 5. Auf die Außenschenkel 4 und 5 v/erden vorgefertigte Spulen 6 bzw. 7 aufgeschoben.As an exemplary embodiment, the figure shows the side view of a core for a double magnetic head with the one according to the invention attached flaps 1. The core has the two columns 2 and 5. Prefabricated on the outer legs 4 and 5 v / earth Coils 6 or 7 pushed on.
Der Lappen 1 erleichtert ganz wesentlich das Einspannen des Kerns in entsprechende Haltevorrichtungen bei der Herstellung und Feinbearbeitung der Spalte, beim Aufschieben der Wicklungsspulen und beim Einbau in die endgültige Magnetkopfhalterung (z. B. Flugscheibe). Sie wird daher erst im letzten Arbeitsgang entlang der Linie A-B abgetrennt. Die Löcher 8 und 9 in dem.Lappen 1 dienen dabei zur genauen Justierung.The flap 1 makes it much easier to clamp the core in corresponding holding devices during manufacture and finishing the gaps when sliding the winding coils and installing them in the final magnetic head mount (e.g. flying disc). It is therefore only cut off along line A-B in the last step. Holes 8 and 9 in dem.lappen 1 are used for precise adjustment.
Es ist zweckmäßig, den eigentlichen, d. h. mit Ausnahme der zunächst fehlenden Spalte durch seine endgültige FormIt is appropriate to use the actual, i. H. with the exception of the initially missing column due to its final shape
