9490

The 9490, also known as TimberLine, is a high-performance information storage and
retrieval system that uses Extended Enhanced tape (called EETape), Enhanced Capacity
cartridge tape (called E-Cart or E-Tape), and standard length cartridges as the storage
medium.

The 9490 supports three tape-recording formats:

36-track, extended (read and write)

18-track, extended (read only)

18-track, standard (read only)

All three recording formats are compatible with the American National Standards
Institute (ANSI) and European Computer Manufacturers Association (ECMA)
specifications.

SD-3

The SD-3, also called RedWood, is a high-performance helical-scan information
storage and retrieval system.

The subsystem reads and writes on half-inch magnetic tape cartridges in
American National Standards Institute compatible helical-scan recording format.
These cartridge tapes are not compatible with linearly recorded cartridges and
are available in the following types:

10 gigabyte “A” cartridge = 91 meters (298 feet)

25 gigabyte “B” cartridge = 204 meters (668 feet)

50 gigabyte “C” cartridge = 392 meters (1,286 feet)

50 gigabyte VolSafe “C” cartridge = 392 meters (1,286 feet)
