The ZRL group is working on developing novel signal processing and
coding techniques that will allow us to push areal densities in tape
storage systems further. Tape systems have unique characteristics that
make the design of new read-channel techniques challenging. Among those
are the interchangeability of the employed storage medium, the variability
in tape speed, which, for example, exacerbates problems related to signal
attenuation and symbol timing recovery, the simultaneous write and read
functionality to and from a number of parallel tracks, and the signal
drop-out effects, to mention just a few. Theoretical and experimental
work allows us to understand and characterize the problems encountered
in tape drive systems and to develop the techniques that will contribute
to making next-generation high-areal density systems a reality. |
