Abstract
A data storage cassette includes an upper cassette half and a lower cassette half and containing therein a tape for storing data. The cassette has an outer shape of a predetermined dimension, and the lower cassette half is formed with a reel lock release hole. A discrimination hole is formed through the lower cassette half at a location adjacent to the reel lock release hole for discriminating the data storage cassette from another cassette having an outer shape of a dimension substantially identical with the abovementioned predetermined dimension of the outer shape of the data storage cassette. A data recording and reproducing device has a discrimination switch or a fixed pin for identifying the presence of the discrimination hole during a loading operation of the data storage cassette into the device and enabling only the data storage cassette to be loaded and set in the device.
