tachometer also helps the system keep track of how much tape is
wound onto each reel and adjusts the speed of the two motors
accordingly. Each time a cartridge is loaded, the drive calculates
and sets the minimum tension required to achieve high-quality,
consistent read/write signals. This calibration system maintains
optimal-contact recording and helps extend the operational life of
the drive.
Self-Cleaning Head
Another important feature that helps extend tape life is the
DLTtape drive’s self-cleaning head design. The write/read/write
elements on the head are aligned vertically on three tiny islands.
This reduces the point of contact with the tape recording surface
to a bare minimum. Along with the write/read/write islands, two
additional islands are included (see Figure 5-5). These extra two
