fitted to the same recoring area as 40 track (the 100 tpi were very
close).
I'm skeptical; in all the time I've bought 5.25 inch floppy diskettes
(since 1976), I've NEVER seen one that had a shorter head window.
I'd be willing to pay $20 for such a diskette for my collection.
I've seen plenty of DRIVES that couldn't step past tracks 34-36, but
that was a mechanical limitation of the drive.
