Abstract
A memory module, releasably attached to the end of a film cartridge, includes a set of conductive arcuate segments surrounding a centrally disposed conductive pad accessible through an upper surface of the module, and non-volatile memory attached to the conductive pad and the arcuate segments. The memory module is positioned so that the conductive pad and arcuate segments can make electrical contact with data recording and reading terminal pins of camera and film processing equipment. The terminal pins include a centrally disposed pin and further pins positioned circularly around the centrally disposed pin to extend into the module and contact the respective conductive pad and segments, so that at least one terminal pin is in contact with each conductive pad and segment. By having a greater number of contact terminals than there are conductive pads and segments, the electronic operating system, on detecting the presence of an inserted cartridge, can identify which of the circularly arranged terminal pins is contacting which of the conductive arcuate segments, and thereafter initiate processing and storage of data in the nonvolatile memory.
