The STT20000A conforms to the QIC-3220-MC development standard adopted by
Quarter-Inch Cartridge Drive Standards Inc. (QIC). The drive records in a serpentine
fashion utilizing a 1,7 RLL (Run Length Limited) data encoding method, and
provides for 108 data tracks and one (1) directory track on Travan TR-5 media.
The drive offers electronically erasable, programmable, read-only memory (flash
EEPROM), which enables qualified Seagate OEMs to download revised firmware to
the drive.
With the availability of greater capacity disk drives and the growth of small networks,
the need for cost-effective, high-capacity storage has grown. The STT20000A is
ideal for high-end standalone computers, workstations, and small networks.
Built using long-wearing materials and custom Large Scale Integration (LSI)
components, the ATAPI drive was engineered for heavy-duty computer applications.
Providing carefully controlled tape handling and rapid, smooth operation, the design
promotes long life for key components such as the motors, drive heads, and the
media itself. One major benefit of this new, computer grade engineering is low
power consumption.
