tape

permanent form, such as perforated paper tape. Generally, tape
is used as a mass storage medium in magnetic form and has a far
higher storage capacity than disk storage, but it takes longer to
write or recover data from tape than from disk.
tape density
The number of characters that can be stored on magnetic media,
such as how close together data can be recorded. The Xerox
LPS may use either 1600 bpi or 6250 bpi density magnetic media.
