Mass store for masses of data

In 1986, NCAR upgraded its mass storage systems with a set of high-density magnetic disks and cassettes linked to the Cray computers then in operation. Some 14 trillion bits of data were moved to the new facility in one of the largest data transfers every accomplished in the research world to that point. Starting in 1989, a StorageTek robotic silo allowed off-line data to be mounted and accessed automatically.
