Abstract

An electrically conductive optical data carrier, useful for music and video recording and play back, has an organic metal, polyaniline, intrinsic conductive polymer (ICP) mixed in its lacquer layer on the reflective layer to make the lacquer layer conductive. Preferably, the disk labels are printed with an organic metal, polyaniline, intrinsic conductive polymer to make them electrically conductive.

Description

Bei der Herstellung von optischen Datenträgern werden digitalisierte Signale, Daten, mit einem fotografischen Verfahren auf eine Glasplatte (Glass Master) gebracht, von dem mit Galvanisierung eine Druckmatrize (Mutter) hergestellt wird. Mit dieser werden Polycarbonat-Platten gepreßt, welche eine Reflexionsschicht aus Aluminium oder Gold erhält. Auf die Metallschicht kommt eine Schutzschicht aus Lack, dann die bedruckte Etikette.In the manufacture of optical data carriers, digitized signals, data, with a photographic process placed on a glass plate (Glass Master), of which with galvanization a pressure matrix (mother) is produced. With this, polycarbonate sheets are pressed, which receives a reflective layer made of aluminum or gold. There is one on the metal layer Protective layer made of lacquer, then the printed label.

Das dabei entstehende Produkt, das während des Abspielens mit unterschiedlicher Drehzahl gedreht wird, erzeugt ein sehr starkes elektrostatisches Feld und generiert in der Photodiode falsche Signale. Dieses Nebeneffekt produziert einen solchen Fehler, womit der DAG (Digital-Analog Converter) nicht mehr zurecht kommen kann. Der Fehler ist eine Art Zeitfehler, Jitter, der praktisch ein null-eins Übergangsfehler ist. Es wird in der Industrie versucht dieses Problem auf unterschiedliche Weise zu bekämpfen, jedoch nur bei Abspielgeräten oder Kabel und nicht die Seite des Mediums selbst.The resulting product, which during playback at different speeds rotated, creates a very strong electrostatic field and generates in the photodiode wrong signals. This side effect produces such an error, with which the DAG (digital-analog Converter) can no longer manage. The error is a kind of timing error, jitter, the is practically a zero-one transition error. This problem is being tried in the industry fight different ways, but only with players or cables and not the Side of the medium itself.

Diese Probleme werden durch die im Patentanspruch aufgeführten Merkmale gelöst. Im Patentanspruch 1. erreichen wir durch die Beimischung von Polyanilin im Schutzlack, eine hohe elektrische Leitfähigkeit. Der in dem Polycarbonat erzeugte Strom wird in der Metallschicht und im Polyanilin weitergeleitet. Die im Patentanspruch 2. aufgeführte, mit Polyanilin bedruckte Etikette leitet der Strom durch direkten Kontakt in die Umgebung.These problems are solved by the features listed in the claim. in the We achieve a high level by adding polyaniline to the protective lacquer electric conductivity. The current generated in the polycarbonate is in the metal layer and in Polyaniline forwarded. The label listed in claim 2, printed with polyaniline conducts electricity into the environment through direct contact.

Die mit der Erfindung erzielten Vorteile bestehen hauptsächlich darin, daß die Anzahl der Lesefehler auf ein Minimum gesenkt wird. Es zeigt sich beim Abspielen von Audioaufnahmen durch eine dramatische Verbesserung der Klangqualität. Bei Videodiscs erreicht man eine Verbesserung des Kontrastes und der Farbsättigung.The advantages achieved with the invention are mainly that the number of Reading errors is reduced to a minimum. It shows up when playing audio recordings by dramatically improving the sound quality. With video discs you get one Improvement of contrast and color saturation.

Die Erfindung kann bei der Herstellung von z. B. Compact Disc, CD-ROM, Videodisc, Laserdisc, CD-I, Digital Versatile Disc, usw. mit erheblichem Qualitätsgewinn eingesetzt werden.The invention can be used in the manufacture of e.g. B. Compact Disc, CD-ROM, video disc, laser disc, CD-I, Digital Versatile Disc, etc. can be used with significant quality gains.
