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