BeschreibungDescription

Beschichtung zur Kennzeichnung von Compäct-Disk-AuslesungenCoating for marking compact disk readouts

Die Erfindung betrifft eine Beschichtung zur Kennzeichnung einer Compact-Disk, um Auslesungen festzustellen. <The invention relates to a coating for marking a compact disk in order to determine readings. <

Bei einer Compact-Disk ist derzeit nicht erkennbar, ob diese in einer entsprechenden Lesevorrichtung ausgelesen bzw. abgespielt wurde..With a compact disk, it is currently not possible to determine whether it has been read or played in a corresponding reading device.

Somit ist es möglich, daß eine Compact-Disk vervielfältigt und das Original beim Händler unberechtigt getauscht oder reklamiert wird. Die wirtschaftlich entstehenden Schäden sind erheblich und können kaum vermieden oder nachgewiesen werden.It is therefore possible that a compact disk is copied and the original is exchanged or returned to the dealer without authorization. The resulting economic damage is considerable and can hardly be avoided or proven.

Der im Schutzänspruch angegebenen Erfindung liegt das Problem zugrunde, eine Beschichtung zur Kennzeichnung einer Compact-Disk-Auslesung zu schaffen, welche eine Abschreckung vor unrechtmäßiger Reklamation und/oder unrechtmäßigem Umtausch ermöglicht.The invention specified in the protection claim is based on the problem of creating a coating for marking a compact disk readout, which enables a deterrent against unlawful complaints and/or unlawful exchanges.

Erfindungsgemäß erfolgt die Lösung der Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen beschrieben. -According to the invention, the object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are described in the dependent claims. -

Mit der Erfindung wird erreicht, daß beim Auslesen einer Compact-Disk eine lang anhaltende Veränderung einer Compact-Disk-Beschichtung eintritt. Händler können somit Kunden unrechtmäßige Reklamationen und/oder unrechtmäßigen Umtausch nachweisen. Wirtschaftlich negative Folgen für Händler, Produzenten, Künstler, Softwarefirmen und Hersteller von derart gekennzeichneten Compact-Disks werden minimiert. ' · . -The invention ensures that a long-lasting change in the compact disk coating occurs when a compact disk is read. Dealers can therefore prove to customers that they have made unlawful complaints and/or exchanged the disks. Negative economic consequences for dealers, producers, artists, software companies and manufacturers of compact disks marked in this way are minimized. ' · . -

In einer vorteilhaften Ausgestaltung der Erfindung wird eine Compact-Disk auf der auszulesenden Seite mit einer Schicht versehen, welche sich durch die Intensität des Leselasers lang anhaltend verändert.In an advantageous embodiment of the invention, a compact disk is provided with a layer on the side to be read, which changes over a long period of time due to the intensity of the reading laser.

Die Erfindung wird nachstehend anhand eines beschriebenen Ausführungsbeispiels einer erfindungsgemäßen Beschichtung näher erläutert.The invention is explained in more detail below using a described embodiment of a coating according to the invention.

Eine mögliche Beschichtung zur Kennzeichnung von Compact-Disk-Auslesungen ist eine auf der Compact-Disk aufgebrachte Schicht, die sich durch den Lesevorgang der Compact-Disk-Lesevorrichtung verändert. Hierdurch wird eine' Compact-Disk auch bei Teilauslesungen gekennzeichnet. Auslesungen - könnten somit mittels entsprechender Vorrichtungen und/oder Farbänderungen der Schicht nachgewiesen werden. ; 'One possible coating for marking compact disk readings is a layer applied to the compact disk that changes as a result of the reading process of the compact disk reading device. This means that a compact disk is marked even when only partial readings are made. Readings - could thus be detected using appropriate devices and/or color changes in the layer. ; '
