"Not an uncommon incident."

It should be. Assuming this story is correct and no apochryphal, the linear motor should have had a speed limiter and a cut out that operated as soon as the linear motor had rotated enough times (if it was geared) or beyond a certain angle (if it was direct drive) that the head would be off the disk or squashed up against the spindle. These are the sort of things industrial systems designers have to consider, obviously the world of HD manufacturers was different back then.
