the upper limits of their potential, DLTtape technology is just hit-
ting its stride, with plenty of room to grow.
Half-inch tape simply offers more growth capacity than the much
smaller 4mm or 8mm formats (see Figure 4-2). Where 8mm and 4mm
are pushing their density limits, half-inch DLTtape technology isn’t even
close to maxing out. For example, the DLT 4000 drive uses 128 record-
ing tracks. The DLT 8000 drive uses the Symmetric Phase Recording
™
pattern, allowing it to lay down 208 tracks on the same half-inch tape.
The next generation of Super DLTtape systems increased track density
yet again, by a factor of more than 2X, to 448 tracks.
Track density is just one parameter. Another is the underlying tape
technology. Today, DLTtape IV cartridges use metal particle (MP)
media. Super DLTtape I cartridges use state-of-the-art Advanced
Metal Powder (AMP) media. AMP media offers increased media
capacity, ease-of-use, and lower cost of ownership. Designed to meet
the needs of multiple generations of Super DLTtape drives, AMP
