Abstract
An electronic data memory is inserted in a recessed surface section on one side of a sheet film cassette. Contact points on the data memory make it possible for the memory to be positively connected, when the sheet film cassette is pushed into a sheet film reader, with the electrical energy supply and the leads for data transfer. The data memory stores cassette-specific data, in particular, an index list. The same data can also be used for selection of cassettes from a filing system.
