I suppose that's possible. One way to do it would be to build a PLL
that's locked to the start of track pulse, and derive a 12x or 16x
sector clock from that. Or, analogously, you could use a PLL to
derive a 16 sector clock from the 12 sector clock (multiple by 4/3rd,
not hard with a PLL). That's probably a good solution...
Hm, and then ignore the "real" sector pulses and feeding the drive
electronics the output of the PLL? Smart, that should work, assuming
one can format the packs given this "sector clock".
Would these then be called hard- or soft-sectored? :)
