ABSTRACT:
An apparatus for the storage and reading of data combined from binary characters, comprising a data carrier having adjacently arranged separate signal conductor tracks incorporating intermediate spaces extending along the columns and separating the conductor tracks, bridge elements provided for the data carrier for the one binary character in the intermediate spaces between the conductor tracks at predetermined intersection points of the columns and lines. The bridge elements interconnecting at the intersection points both of the conductor tracks of a relevant column with one another. The bridge elements are reversibly activatable from a first condition which can be detected via the conductor tracks of the columns through an external action into a second condition portraying a binary character and detectable via the conductor tracks, and for the other binary character the conductor tracks at the relevant other intersection points of the columns and lines are selectively either not interconnected with one another or interconnected by such bridge elements. Means are provided for rendering ineffectual from the outside the external action of such other bridge elements for retaining the same permanently in the first condition portraying this other binary character. A reader is provided having means for generating the action in a region corresponding to a line of the data carrier, a feed mechanism for moving relative to one another the data carrier and the means generating the action in order to bring about a line-by-line scanning of the data carrier, an evaluation device, and a detector operatively connected with the evaluation device for producing output signals for the evaluation device for determining the state of the bridge elements of the data carrier via its conductor tracks. The detector including a control device for the columnwise connection of pairs of conductor tracks determining the individual columns, said detector being designed such that its output signals in the case of bridge elements activated by the external action and connected therewith via a pair of conductor tracks possesses a first signal value portraying the one binary character and otherwise a second signal value portraying the other binary character.
