A tape library (robotic library) is a high-capacity storage device that contains the following:
Each tape may have a special label attached to the side of a cartridge and comprise of:
Such labels are used for tape identification in a tape library or especially in off-site storage.
If all cartridges in a tape library have barcodes, the library is ready to be automatically managed by software.
Tape libraries are a cost-effective solution for data storages with huge capacity. Moreover, tape is perfect for archiving because cartridges can be stored off-site for enhanced data security. However reading even a small amount of data from a tape library takes much more time (from several seconds to several minutes) than from other types of data storages. The best practice of tape usage is “LESS requests to write/read LARGER amount of data”. So systematic access to very large quantities of data is more suitable for a tape library than random access to small portions of data.
