Instead, the write-read heads are logically or mechanically switched to a different
position on the tape and another track is written or read in the reverse direction.
That is, the drive first records track 1 in one direction and when the end of the tape
is reached, the head is moved and the direction of tape motion is reversed to record
track 2. This serpentine process continues until the entire tape is recorded. The
individual tracks are sequential to minimize the amount of head motion as the heads
change position for each track.
The STT20000A incorporates leading-edge technology in the flash EEPROM, which
is useful should the drive's firmware need to be upgraded at some point. With the
permanently installed, electrically upgradeable, flash EEPROM memory, revised
firmware for the drive can be loaded via any one of two methods:
•
Seagate OEM firmware cartridge (See chapter 4)
•
Host IDE bus
This feature enables qualified OEMs needing to revise the drive firmware to do so
rapidly and at a reduced cost. Flash EEPROM should also prolong the life cycle of a
drive because many new techniques—such as increasing the capacity of the drive
through support for longer tapes—may require only a firmware upgrade.
The STT20000A is a cost-effective means of backing up fixed disks. The drive is

compatible with DOS version 5.0 or later, Microsoft Windows
Microsoft Windows 95, or Windows NT and will operate with many of the popular
backup software applications such as Seagate 's Backup for DOS and Windows,
Windows 95, NetWare, or Windows NT.
