Die Erfindung betrifft ein Verfahren zvr Erzeugung von vorzugsweise mechanisch abtastbaren reliefartigen Vertiefungen oder Erhebungen auf der Oberfläche eines Informationsträgers mittels eines Laser- oder Elektronenstrahls, dem eine zu speichernde Information aufmoduliert wird. Es ist dabei daran gedacht, daß die zu speichernde Information dem Aufzeichnungsstrahl entweder direkt oder über einen Zwischenträger aufmoduliert werden kann, wobei insbesondere an Frequenzmodulation oder Impulszeitmodulation gedacht ist.The invention relates to a method for producing, preferably mechanically scannable relief-like depressions or elevations on the Surface of an information carrier by means of a laser or electron beam, the one to be stored Information is modulated. It is thought that the information to be saved can be modulated onto the recording beam either directly or via an intermediate carrier, with frequency modulation or pulse time modulation being thought of in particular.
Es ist bereits vorgeschlagen worden, die Abtragung oder Verformung der Oberfläche des Informationsträgers mit Hilfe eines durch die zu speichernden Informationen modulierten Flek'.ronen- oder Laserstrahls vorzunehmen, das Auslesen dieser gespeicherten Informationen aus der Trägeroberfläche jedoch durch mechanische Abtastung dieser Oberfläche durchzuführen. Insbesondere ist der Vorschlag gemacht worden, zur Auslesung der gespeicherten Informationen einen auf Druckänderungen ansprechenden Abtaster zu verwenden, wobei der zur Verwendung kommende Träger sowie dieser Druckabtaster derart ausgebildet sein sollen, daß die durch die Druckkraft bewirkte elastische Formänderung der die Informationen enthaltenden Trägeroberfläche wesentlich größer ist als die korrespondierende, auf der Zusammendrückung beruhende Auslenkung der Berührungsfläche des Abtasters.It has already been proposed to remove or deform the surface of the information carrier with the help of a Flek'.ronen- or laser beam to read this stored information from the carrier surface but to be carried out by mechanical scanning of this surface. In particular, the proposal is have been made to read out the stored information on pressure changes to use appealing scanner, with the support to be used as well as this Pressure sensors should be designed in such a way that the elastic change in shape caused by the pressure force the carrier surface containing the information is much larger than the corresponding one, deflection of the contact surface of the scanner due to the compression.
Diese Wiedergabemethode und die demzufolge notwendige Ausbildung der Trägeroberfläche und des Abtasters ermöglichen es, Informationen zu speichern und wiederzugeben, die ein sehr breites Frequenzband Tirt-fassen. Es ist mit diesem vorgeschlagenen Prinzip beispielsweise möglich, auf einem solchen Informationsträger, z. B. einer Plnte mit spiralförmigen Aufzeichnungsspuren, Bildinformationen zu speichern und auf dem angegebenen mechanischen Wege abzutasten, um diese Bilder dann auf dem Bildschirm eines Fernsehempfängers wiederzugeben.This reproduction method and the consequent necessary formation of the support surface and of the scanner make it possible to store and reproduce information covering a very wide frequency band Tirt-grasp. It is suggested with this Principle possible, for example, on such an information carrier, e.g. B. a plan with spiral recording tracks to store image information and on the specified mechanical ways to scan in order to then display these images on the screen of a television receiver to reproduce.
Der Erfindung liegt die Aufgabe zugrunde, den Aufzeichnungsvorgang auf einem solchen Informationsträger zu vereinfachen. Erfindungsgemäß wird auf den Informationsträger zunächst eine Schicht aus einem solchen Material und in einer derart geringen Dicke aufgebracht, daß sie einerseits durch einen auf ihr auftreffenden Elektronen- oder Laserstrahl leicht verdampfbar, andererseits aber gegenüber einer auf das Trägermaterial einwirkenden Ätzflüssigkeit resistent ist. Nach der entsprechend der Information erfolgten Verdampfung von Teilen der aufgebrachten Schicht wird die Trägeroberfläche zwecks Reliefvertiefung einem Ätzvorgang oder einem galvanischen Aufwachsvorgang unterworfen.The invention is based on the object of the recording process on such an information carrier to simplify. According to the invention, a layer is first applied to the information carrier made of such a material and applied in such a small thickness that they on the one hand by an electron or laser beam hitting it easily vaporizable, but on the other hand opposite is resistant to an etching liquid acting on the carrier material. According to the Information about evaporation of parts of the applied layer becomes the support surface subjected to an etching process or a galvanic growth process for the purpose of relief deepening.
Den Träger wird man zweckmäßigerweise aus Metall, z. B. Nickel, Silber, Kupfer, ausbilden; es wäre jedoch auch möglich, einen solchen Träger aus Keramik herzustellen. Die aufzubringende dünne Schicht soll vorzugsweise aus Magnesium, Cadmium, Zink, Blei, Wismuth oder Aluminium bestehen.The carrier is expediently made of metal, e.g. B. nickel, silver, copper, train; it however, it would also be possible to manufacture such a carrier from ceramic. The thin to be applied The layer should preferably consist of magnesium, cadmium, zinc, lead, bismuth or aluminum.
Im Falle der Verwendung einer Aluminiumschicht wird die Trägeroberfläche zweckmäßigerweise nach der erfolgten Einwirkung des Laser- oder Elektronenstrahls einem Oxydationsvorgang unterworfen, so daß der nach der Einwirkung des Elektronen- oder Laserstrahls verbleibende Teil dieser Schicht in sein Oxyd (Λ12Ο3) umgewandelt wird. Diese Aluminiumoxydschicht ist besonders resistent gegenüber Ätzflüssigkeiten, die verwendet werden, um gemäß der Erfindung eine Vertiefung des entstandenen Reliefs zu erzielen.If an aluminum layer is used, the support surface is expediently subjected to an oxidation process after the action of the laser or electron beam, so that the part of this layer remaining after the action of the electron or laser beam is converted into its oxide (Λ1 2 Ο 3 ). This aluminum oxide layer is particularly resistant to etching liquids which are used in order to achieve a deepening of the resulting relief according to the invention.
Der Vorteil der Erfindung besteht in erster Linie darin, daß für den Schreibvorgang eine verhältnismäßig geringe Strahlleistung erforderlich ist, weil die beispielsweise nur 500 A Dicke aufweisende Schicht, die im Falle von Aluminium und Umwandlung des Aluminiums in Aluminiumoxyd wegen dessen höherer Resistenz noch geringer sein kann, durch den auftreffenden Laser- oder Elektronenstrahl leicht verdampfbar ist. Die für einen mechanischen Abtastvorgang oder eine andersartige Wiedergabe notwendigen Vertiefungen oder Erhebungen werden dann in einem zweiten Schritt durch Ätzen oder galvanische Verstärkung hergestellt. An Stelle der erwannten mechanischen Abtastung läßt sich ein so behandelter Träger auch "1Is Matrize zum Drucken der auf ihn aufgebrachten Informationen verwenden. Man kann also beispielsweise auf den Träger in derThe advantage of the invention is primarily that a relatively low beam power is required for the writing process because the layer, for example only 500 Å thick, which in the case of aluminum and the conversion of aluminum to aluminum oxide can be even lower because of its higher resistance , can easily be vaporized by the incident laser or electron beam. The depressions or elevations necessary for a mechanical scanning process or a different type of reproduction are then produced in a second step by etching or galvanic reinforcement. Instead of the mechanical scanning erwannten a so-treated carrier can also use "1 Is a template for printing applied to him information. So you can, for example, to the support in the

By applying a new one Another advantage of the inventive layer is again one that is ready for exposure driving consists in the fact that the carrier is readily available for 5 carriers.
