5.18 StorageTek Helical

    Storage Tek has been working on a project called Redwood for a number
of years. The cartridge will be 3480 form-factor, to protect users'
investment in Storage Tek robotics. (rdv@alumni.caltech.edu (Rod Van
Meter)) Cartridges come in three lengths, with capacities of 10, 25
and 50 GB. That would put one of their 6,000-cartridge silos up to 300
TB.
