Abstract
Description
Scheibenförmiger Träger für mechanisch, magnetisch,Disc-shaped carrier for mechanical, magnetic,
oder optisch aufgezeichnete Ton- oder Bildinformationen, insbesondere für Archiv- oder Sammlerzwecke.or optically recorded audio or video information, in particular for archival or collector purposes.
Die scheibenförmigen Informationsträger z.B. die Bild-und Schallplatten, weisen einen schwerwiegenden Nachteil auf: sie werden bei der Benutzung mechanisch beansprucht und unterliegen dabei einer unvermeidlichen Abnutzung, welche um so grösser ist, je öfter die Benutzung erfolgt.The disc-shaped information carriers e.g. the picture and record discs, have one serious drawback: they become mechanical with use stressed and are subject to inevitable wear and tear, which is so is greater, the more often it is used.
Die Abnutzung ist zwangsläufig mit der laufenden Verschlechterung der Wiedergabequalität verbunden, sodass mit der Gebrauchszeit die Aufzeichnung immer mehr an Aussagekraft und Wert verliert.The wear and tear is inevitable with the ongoing deterioration connected to the playback quality, so that with the usage time the recording increasingly loses its expressiveness and value.
Dazu kommt, dass in der Mehrzahl der Fälle der Aufzeichnung auf der A-Seite, eine wenig oder überhaupt nicht gefragte Aufzeichnung auf der B-Seite als Füllmaterial beigegeben wird.In addition, in the majority of cases the recording is made on the A-side, a little or no demanded record on the B-side as Filler material is added.
Diese Nachteile werden nach der vorliegenden Erfirpdung vermieden, indem bei scheibenförmigen Trägern mit mechanisch, magnetisch oder optisch aufgezeichneten Ton- oder Bildinformationen die B-Seite die genau gleiche Aufzeichnung der A-Seite als Duplikat trägt und beide Seiten derart unterschiedlich gekennzeichnet oder ausgeführt sind, dass eine unbeabsichtigte Benutzung vermeidbar ist.These disadvantages are avoided according to the present invention, by mechanically, magnetically or optically recorded on disk-shaped carriers Sound or picture information the B-side is the exact same recording of the A-side as a duplicate and both sides marked or executed differently are that unintentional use can be avoided.
Wird z.B. die A-Seite für Archiv- und Sammlerzwecke geschont, d.h. für Normaigebrauch nicht genützt, so kann jedoch die B-Seite jederzeit die genau gleiche Aufzeichnung der A-Seite wiedergeben. Es steht also immer, trotz oftmaligen Gebrauchs der B-Seite die neuwertige oder nahezu neuwertige genau gleiche Aufzeichnung auf der A-Seite für höchste Ansprüche zur Verfügung.If, for example, the A-side is spared for archiving and collecting purposes, i.e. not used for normal use, but the B-side can always use the exact play back the same recording of the A-side. So it always stands, despite frequent When the B-side is used, the recording is as good as new or almost as good as new available on the A-side for the highest demands.
Die vorliegende Erfindung stellt die günstigste wirtschaftliche Lösung für die Plattenproduktion dar, denn ohne zusätzlichen apparativen und materiellen Aufwand wird, selbst wenn keine Archiv- oder Sammlerzwecke verfolgt werden, die doppelt lange Gebrauchsdauer erreicht, unter gleichzeitiger Einsparung der Kosten, welche das sonst übliche und überflüssige Aufzeichnungsfüllmaterial der B-Seite erfordert.The present invention represents the most favorable economical solution for the record production, because without additional equipment and material Even if no archival or collector purposes are pursued, the effort will be made twice the service life achieved while saving costs at the same time, which is the usual and superfluous recording filler material for the B-side requires.
