VHS quality 24 bits x 640 pixels x 480 lines x 30 Hertz x 3600 seconds
is 100 gigabytes uncompressed.
Sun TAAC compresses digital video to 5-10%, but this is still a lot of
storage.
The now defunct company called PEL offered a system in 1980 with one minute
of video using a gigabyte disk farm.
The National Supercomputer Center uses an Abacus (spelling?) system for
digital video loops on the order of a minute.
The Connection Machine plus Data Vault can store hour long movies at this
resolution, but is expensive.   It is an impressive digital movie machine.
