Yup, succumbing to nostalgia for a paragraph, I recall with some 
distaste my attempts to make one of a pair of 14" Dynax drives in an 
old TI mainframe work reliably in the winter of 77-78 at KRCR-TV.  
The bottom one was fairly dependable, but the top one would go into 
safe park at the execution of a simple seek.  Voice coil driven, the 
voice coils were about 4" in diameter and 6" long.  They used an 
optically striped tape and photocells in quatrature timeings to 
determine where it was at.  Recalibration, if you had everything 
handy, was about a 6 hour job.  After I did it the 5th or 6th time, 
with no improvement in its dependability, I told management to sue 
them.  As we'ed already burnt 40+ hours on the phone to tech support 
then, I think the threat must have been enough, they sent somebody in 
with a new drive which worked.  I was out doing something else so I 
missed all the fun.  By design...
