A nice idea, but I wonder if it would help? You'd need a lot of cache
memory for one complete revolution x no. of surfaces, and the data
transfer rate of the HD interface might be the limiting factor anyway.

Yes, that's the whole point of this discussion.
See http://www.storagereview.com/guide2000/ref/hdd/geom/tracksZBR.html
for a table showing a typical drive. The transfer rates vary from 372
Mb/s in zone 0 to 173.8 in zone 14.
