High data density label and system using same

摘要

A system for identifying and managing a plurality of objects includes a high data density label. The label includes an optical media portion configured to store data in an optical format. The optical media portion has a high areal density and may be rewritable. The high data density of the label allows a large amount of information to be stored directly on the label. The data can be quickly read from the label without requiring physical contact with the label. A read device is provided for reading data from a selected label. A write device is provided for modifying the data in a selected label. The preferred embodiment of the labeling system is implemented in an information storage system using an automated cartridge system (ACS). The labels are attached to physical volumes (e.g., tape cartridges) stored in the ACS. The labels are used to identify and manage information stored on the physical volumes as well as the physical volumes themselves.
