摘要：
Data storage apparatus comprises a tape drive and a tape cartridge, the tape cartridge having a data storage tape on which write-once-read-many (WORM) data is stored. The data storage apparatus is controlled by providing a format command to the tape drive commanding a formatting operation that conditions the tape for erasure or overwriting of the WORM data. A format command key is provided with the format command to be compared with a key recorded in the cartridge. The format command is enabled in dependence upon the comparison between the format command key and the recorded key.
