<<As I recall, these demos have typically lead the production drives by 2 to 2.5 years.

Which just happens to be the time frame which would put areal density growth going forward at 100 percent compounded annually, the same rate experienced for the last 2 years.

LT, true, spin stands don't do the kind of seeking drives
do. But they do access different tracks and read offtrack
to stress the process. Offtrack performance [error rate
while the head misregistered a certain percentage of track
width ]has been a key measure for determining feasibility
of a new design. Designers estimate the track
misregistration [TMR] a new drive may see, then test on the
spin stand after dialing in that TMR.
