Re: "Yes, doing the 'radial alignment' is not that hard. I've never had
any
success with the 'digital alignment disks', I prefer a 'catseye disk' and
an oscilloscope conencted to the differential outputs of the read
amplifier."
The digital alignment disks are intended for checking alignment to see if it
needs to be done. It's not practical to use them for actually doing the
alignment. It's not impossible, absolutely, but it's not a good way to go
about it, nor was it really the intent of the digital disks.
