Disc-shaped information storage

The invention relates to a disk-shaped information memory.

Up until now it was possible to store information "in disk form", e.g. B. to make records with different information in the catfish that, in addition to the embossed identification, a printed label with the number of the record and its title has been applied to one or both sides of the record. Novel *. .? Ten-shaped information storage media made of particularly thin carrier material include the possibility of producing a multiple of the previous number of plates, whereby the number of stored subjects can also be much higher than before.

The quick finding and cataloging of the large amounts of different information requires a system of plate identification, which

Finding certain information and thus the plates on which this information is fixed,

The main object of the invention is to provide a possibility of disk-shaped information storage or information carriers in a quick and simple manner from a large number of information stores to select, for example, a plurality of selected information stores that relate to a specific topic contain, form and / or evaluate acoustically.

The object is achieved according to the invention in that on the plate, on the edge of the plate or on one with her connected part recesses, deformations, elevations or the like. As coding elements for querying the content of the Plate and / or a part of the plate and for sorting out a plate with the desired content from a plurality of Plates are provided.

For the selection of one or a plurality of disk-shaped information memories with the features of the invention Appropriate scanning elements can be provided which are based on mechanical, magnetic, electromagnetic or optical basis.

Through the appropriate selection of coding elements of the pre-marked type, either alone or in combination, it is possible to sense a large number of information memories one after the other in such a way that, for example, a stack or a memory of many thousands of information memories can be scanned within a very short time and the desired disk can be sorted out .

According to one embodiment of a plate-shaped Information store according to the invention can

Another embodiment dee plate-shaped Information memory according to the invention welit one with the information memory releasably or non-releasably connected carrier that carries the encoder elements.

The invention is explained below with reference to the drawing for example explained:

Flg. 1 shows a plan view of a plate-shaped one Information store according to the invention.

Flg. Figure 2 shows a cross-section through another

of a disk-shaped information memory according to the invention.

In Fig. 1, the reference numeral 1 denotes a disk-shaped information memory according to the BfJadung. On the periphery of the information memory 1, coding elements are attached in the form of notches 2 for interrogating the contents of the disk and for sorting out from a plurality of disks. In Fig. 1, 5 denoted elevations or deformations K on the information memory 1 are shown,.

In Flg. 2 shows a further embodiment of a plate-shaped information memory 1 'cross section. The cross-sectional view shows elevations and deformations which are arranged on the base of the disk-shaped information memory .

The information memory can consist of a translucent or a borne or reflective material. When creating the information, you can use buckets of transparent material Coding elements made of non-permeable material be used.

Claims (5)

Protection; claims 1. Disc-shaped information memory, characterized in that on the plate (l), at the edge of the plate or on a part connected to it, recesses, deformations, elevations or the like as coding elements (2 or 5 or 4) to query the content of the plate and to sort out a plate with the desired content a plurality of plates are provided. 2. Disc-shaped information memory according to claim 1, characterized in that the coding elements (2 or 3 or 4) or some of the coding elements the disk-shaped information memory (1) are applied. 3. Disc-shaped information storage after a of claims l or 2, characterized in that the Coding elements (2 or 3 or 4) are arranged at points not used by the information storage. 4. Disc-shaped information memory according to one of claims 1 to 3, characterized in that the Coding elements (2 or 3 or 4) are wholly or partially attached to a separate carrier releasably connected to the plate-shaped information memory. 5. Disc-shaped information memory according to one of claims 1 to 4, characterized in that the Coding elements (2 or 3 or 4) in whole or in part are attached to a separate carrier inextricably connected to the plate-shaped information memory. 710226113.1Z73
