Abstract

The data-pin has a cylindrical shape provided by thirteen superimposed transparent layers. Data can be stored in the arrangement via a laser providing a variable intensity controlled laser beam, modulated by the data. The laser may be coupled to a filter system, with a given filter activated for each laser beam intensity, for filtering different laser frequencies.

Description

Anwendungsgebietfield of use (Wiedergabe des Oberbegriffs des Patentanspruchs 1)(Reproduction of the generic term of Claim 1)

Die Erfindung betrifft einen Datenspeicher, der bei relativ weniger Volumen mehr Daten speichern kann als andere Datenträger wie z. B. eine CD.The invention relates to a data memory that is relatively less Volume can store more data than other disks like e.g. B. a CD.

Zweckpurpose

Da herkömmliche Datenträger (z. B. Disketten, CD's) nur eine relativ kleine Speicherkapazität besitzen, benötigt man, um größere Daten­ mengen zu speichern, mehrere von ihnen; und dies raubt Platz. Durch die Zylinderform des Data Pin's und den verschiedenen transparenten Schichten wird ein ca. Dreifaches der Speicherkapazität einer CD er­ möglicht (mind. 2,4 GB).Since conventional data carriers (e.g. floppy disks, CD's) are only relative have small storage capacity, one needs to larger data save quantities, several of them; and this takes up space. By the cylindrical shape of the data pin and the various transparent ones Layering becomes approximately three times the storage capacity of a CD possible (at least 2.4 GB).

Kritik des Standes der TechnikCritique of the state of the art

Für ein Computerprogramm, ob zur Unterhaltung oder zur Steuerung von Computerfunktionen, werden heute mehrere CD's oder Disketten benötigt. Man muß also für ein Computerprogramm mehr Geld beim Kauf ausgeben, wenn es die Größe einer normalen CD überschreitet. Neue Computerprogramme überschreiten schnell die Größe einer CD, da diese Programme immer komplexer werden, um dem Käufer z. B. bessere Grafiken und Sound's bei Heimcomputern oder industriellen Käufern z. B. bessere Software für ihre Fabriken zu bieten.For a computer program, whether for entertainment or for control of computer functions, are today several CDs or floppy disks needed. So you have to spend more money on a computer program Spend purchase if it exceeds the size of a normal CD. New computer programs quickly exceed the size of one CD as these programs become more complex to the buyer e.g. B. better graphics and sounds for home computers or industrial buyers e.g. B. Better software for their factories too Offer.

Aufgabetask

Der Erfindung liegt die Aufgabe zugrunde, mehr Daten als herkömm­ liche Datenträger zu speichern und durch die besondere Form (Zylinderform) weniger Platz als andere Datenträger einzunehmen.The invention has for its object more data than conventional storage media and the special shape (Cylindrical shape) take up less space than other data carriers.

Lösungsolution (Wiedergabe des kennzeichnenden Teils des Patentanspruchs 1)(Reproduction of the characteristic Part of claim 1)

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, Daten­ informationen auf 13 transparenten Schichten in einer Zylinderform zu speichern.According to the invention, this object is achieved by data information on 13 transparent layers in a cylindrical shape save.

Weitere Ausgestaltung der Erfin­ dungFurther development of the Erfin dung (Wiedergabe des kennzeichnenden Teils eines Unteranspruchs)(Reproduction of the characteristic Part of a sub-claim)

Um den Data-Pin (englisch-Datenstift) überhaupt lesen zu können, ist ein vollkommen neues Laufwerk von Nöten, welches durch die Form des neuen Datenträgers nur die Hälfte des Platzes eines CD-Lauf­ werkes in Anspruch nimmt. Außerdem beinhaltet das DP-Laufwerk einen in seiner Lichtintensität variablen Laser und ein Filtersystem, welches der reflektierte Laser durchläuft. Ohne diese beiden Systeme könnten die Daten des DP's nicht gelesen werden.In order to be able to read the data pin at all, is a completely new drive is needed, which by the form of the new disk only half the space of a CD run works. The DP drive also includes a laser with variable light intensity and a filter system, which the reflected laser passes through. Without these two systems the data of the DP could not be read.

Erzielbare VorteileAchievable advantages

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, nicht mehr eine Vielzahl von herkömmlichen Datenträgern für ein größeres Programm zu benötigen, sondern nur noch einen DP, der Programme bis etwa zu einer Größe des ca. Dreifachen einer CD speichern kann und die durch die Zylinderform hervorgerufene Platz­ einsparung (deutlich weniger Volumen als drei CD's). Das Laufwerk des DP's besitzt nur die Hälfte der Größe eines CD-Laufwerks, so kann man ebenfalls Platz in Computern für weitere Hardware sparen.The advantages achieved with the invention are in particular no longer a variety of conventional disks for one need a larger program, but only a DP that Programs up to approximately three times the size of a CD can save and the space created by the cylindrical shape saving (significantly less volume than three CD's). The drive the DP's is only half the size of a CD drive, so you can also save space in computers for additional hardware.

AusführungsbeispielEmbodiment

Die Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Da die Erfindung vom CD-System abgeleitet ist, ist dieses zuerst auf der Zeichnung abgebildet, außerdem befinden sich auf der Zeichnung die Maße und Berechnungen zu CD und DP als Vergleichsmöglichkeit. Der DP funktioniert nach nahezu dem selben System, wie die CD.The invention is illustrated in the drawing and is described below described in more detail. Since the invention is derived from the CD system, is this first shown on the drawing, as well as located on the drawing the dimensions and calculations for CD and DP as a way of comparison. The DP works on almost the same system as the CD.

Ein Laserstrahl wird ausgesendet, in einem bestimmten "Muster" von der CD reflektiert, vom transparenten Spiegel zur Photodiode abge­ lenkt, die nun die ankommenden Lichtsignale in kleine Stromstöße umwandelt, welche die eigentlichen Daten darstellen. Bei dem System zur Datenlesung des DP's verhält es sich ähnlich. Es existieren nur zwei wesentliche Unterschiede. Der Laserstrahl muß, je weiter er ins Innere des DP's vorstößt, an Lichtintensität etwas zunehmen und ein Filtersystem den reflektierten Strahl "filtern". Da der DP aus 13 transparenten Schichten besteht lassen sich Daten­ überschneidungen des eintreffenden und reflektierten Laserstrahls nicht vermeiden. Jede der 13 Schichten reflektiert das Licht in einer anderen Frequenz - nur so ist die Filterung überhaupt erst möglich.A laser beam is emitted in a certain "pattern" from the CD reflects, from the transparent mirror to the photodiode which now directs the incoming light signals into small surges  converts which represent the actual data. In which The system for reading data from the DP is similar. It there are only two major differences. The laser beam must the further he penetrates into the interior of the DP, the more light intensity there is increase and a filter system "filters" the reflected beam. Since the DP consists of 13 transparent layers, data can be overlaps of the incoming and reflected laser beam do not avoid. Each of the 13 layers reflects the light in one other frequency - this is the only way that filtering is possible in the first place.
