Abstract

The process permits the production of read-only optical storage disks in one operation in an injection-moulding machine together with the metal reflective coating. A polymer film is used as the substrate for the metal reflective coating. The said film sets in the mould under the pressure and temperature of the injected polymer substrate melt and simultaneously forms an image of the information bits on the metal coating.

Description

Die Erfindung betrifft das Verfahren zum Herstellen von nur lesbaren optischen Speichern, insbesondere als Video Long Play, Audio Compact Disc (CD), ein Daten- Speichersystem nach dem CD Audio-Prinzip, CD Interactive (CD-J), eine Kombination von Audio-, Bild- und Text­ speicher.The invention relates to the method for manufacturing of readable optical memories in particular as video long play, audio compact disc (CD), a data Storage system based on the CD audio principle, CD Interactive (CD-J), a combination of audio, image and text Storage.

Es ist bekannt, daß die Metallreflextionsschicht auf den Speicherplatten nach dem Informationspits Auftragung aufgedampft bzw. aufgesputtert wird (Ber. Bunsenges. Phys. Chem. 89, 1183 (1985) VCM Verlagsgesellschaft mbH). (A.E. Bell "Optical Disk Storage Technology: Past and Futur") Tutorial B.: Optical Medie Technology (Int. Soc. for Optical Engineering. Brüssel 26.04.84, N. Imemune, AEK April 1985, 97).It is known that the metal reflection layer is on the storage disks after applying the information pits is evaporated or sputtered (Ber. Bunsenges. Phys. Chem. 89, 1183 (1985) VCM Verlagsgesellschaft mbH). (A.E. Bell "Optical Disk Storage Technology: Past and Future ") Tutorial B .: Optical Media Technology (Int. Soc. for Optical Engineering. Brussels 26.04.84, N. Imemune, AEK April 1985, 97).

Dies verlangt Anwendung von Vacuumbeschichtungsanlagen und Übertragung von Platten von der Spritzgießmaschine bzw. Presse auf der Vacuumsbeschichtungsanlage, wobei der ganze Prozeß im Reinraum Klasse 100 laufen muß.This requires the use of vacuum coating systems and transfer of plates from the injection molding machine or press on the vacuum coating system, whereby the whole process must run in class 100 clean room.

Der Erfindung liegt die Aufgabe zugrunde, die komplizier­ te und teure Vacuumsbeschichtungsanlage aus dem Her­ stellungsprozeß von Speicherplatten auszuschließen und die Platten in einem Arbeitsgang auf der Spritzgieß­ maschine mit Metallreflextionsschicht zu beschichten.The invention has for its object the more complicated expensive and expensive vacuum coating system from the manufacturer exclude position process from storage disks and the plates in one step on the injection molding to coat the machine with a metal reflection layer.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Metallreflextionsschicht in einem Arbeitsgang auf der Spritzgießmaschine mit dem Substratpolymer fest verbunden wird. Zusätzliche Vorteile bestehen auch da­ rin, daß die entsprechende Kombination von Substratpolymer und metallbeschichtete Folie die Doppelbrechung des Laser­ strahles verringern kann.This object is achieved in that the metal reflection layer in one operation the injection molding machine with the substrate polymer is connected. There are also additional advantages rin that the corresponding combination of substrate polymer and metal-coated film the birefringence of the laser can reduce beam.
