Abstract
A library of disk media units for use in a data processing environment wherein receptacle columns hold multiple cartridges which in turn hold multiple media units comprised of caddies and recording disks. A picker system moves media into and from the drive units and receptacle columns. Drive units are also located within the receptacle columns. The caddies and cartridges are supplied with hole patterns to coact with optical sensors within the receptacle columns and thereby provide information to the library controller indicating the proper/improper operation of the picker system in positioning media units. Also, the hole pattern on the media unit enables the sensors to provide informational content about the media unit to the processor.
