A data storage cartridge for a data storage disk drive has a latent illuminance marker. A light source illuminates the marker and the marker emits illuminance as phosphorescence. A photosensor detects the emitted illuminance, and the decay time is determined. The decay time is checked to provide identification of different types or generations of data storage cartridges.
