The drive is equipped with a 512-Kbyte on-drive buffer to facilitate efficient
operation.
The STT20000 SCSI minicartridge drive supports the QIC-3220-MC format standard
and will provide 10 gigabytes uncompressed storage capacity, 20 gigabytes
compressed, with a Travan TR-5 cartridge. The drive will also read tapes
conforming to the QIC-3095 standard (TR-4).
A precision-burst intelligent positioning system is used to achieve high track
densities.
The STT20000 SCSI minicartridge drive 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 SCSI-storage has grown. The STT20000
SCSI minicartridge drives are ideal for high-end stand-alone computers,
workstations, and small networks.
Built using long-wearing materials and custom Large Scale Integration (LSI)
components, the drive was engineered for heavy-duty computer applications.
Providing carefully controlled tape handling and rapid, smooth operation, the drive
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.
