Hold large volumes of data and provide high transfer rates
Few GB for DAT (Digital Audio Tape) format, 10-40 GB with DLT (Digital Linear Tape) format, 100 GB+ with Ultrium format, and 330 GB with Ampex helical scan format
Transfer rates from few to 10s of MB/s
Currently the cheapest storage medium
Tapes are cheap, but cost of drives is very high
Very slow access time in comparison to magnetic disks and optical disks
limited to sequential access.
Some formats (Accelis) provide faster seek (10s of seconds) at cost of lower capacity
Used mainly for backup, for storage of infrequently used information, and as an off-line medium for transferring information from one system to another.
Tape jukeboxes used for very large capacity storage
(terabyte (1012 bytes) to petabye (1015 bytes)
