Abstract

Electrical contact surfaces, especially when connected to a chip, are designed to be purely functional. However, according to the present disclosure, the contact surfaces are designed so that their external shape is that of a visible letter or symbol with a meaningful content. These contact surfaces may, e.g., be placed on cassette casings for recognition. In a stripe or bar code unit consisting of several code components, i.e., bars, individual bars are electrically conductive to facilitate additional coding. The electrically conductive bars or the contact surfaces are preferably connected to the terminals of an integrated circuit.

Claims11

Dependent claims

Recording cassette or diskette comprising:

means, arranged on a housing, for providing electrical contacts which include a plurality of electrically conductive contact elements which are constructed, at least partially with respect to one another, to be electrically insulated from one another,
the external shape of the contact elements being designed as a pre-known graphic character(s), as parts of these graphic character(s), or as the interspaces within these graphic character(s),
the contact elements either being coupled to circuit means in which information relating to the recording cassette or diskette is contained and/or can be stored, and/or some of the contact elements are coupled to other contact element(s) so that the type of these connections codes information on the recording cassette or diskette,
wherein said information relating to one of the recording cassette or diskette includes information which is different from the information which is represented by said pre-known graphic characters.
