With regard to data separators for reading magnetic
media in real time, I would agree with you. However, for archiving legacy magnetic media,
a DPLL in software has the potential to be far better than any analog PLL, precisely
because it is effectively possible to throw an arbitrary amount of computation at it.
After all, legacy media (and the equipment that made it) can have problems.
Which method handles problems best? Are some problems (like misaligned tracks)
only solvable by alternative reading hardware?
