Subject: Re: Alignment disks, and the creation thereof
The problem comes if you want 2 offset tracks say
180 drgrees out of phase
(so one is at its innerpost point when the other is at the outermost point).
Aligning the media to the offset hub accurately to do that would
be 'interesting'.
Didn't the Lisa have floppy drives with heads on opposite sides of the
spindle? :-)
YEs, but that wouldn't help. What you need to vary is the angular
position between the media and the offset spindle. Having a second head
180 degrees from the normal one has the same effect as rotating the
spindle _and media toghether_ throuhg 180 degrees.

Hi
Might it be easier to just turn the hub down by half a track.
When you mount the disk just make sure it is touching the hub.
