Figure 18. Layout of tracks on LTO Ultrium tape

There are 384 data tracks on the LTO tape, numbered 0 through 383. Data track 383
is the track closest to the bottom edge of the tape (the reference edge). The area
between adjacent servo bands is a data band. There are 4 data bands, each of
which includes 96 data tracks. The data bands are numbered 2,0,1,3. Data band 2 is
closest to the bottom edge of the tape.
