I don't know what the density is on DECtapes but I presume it was fairly low
and they could get away with the lamination, or they traded off bit density for
robustness.
And then there were DECtapes (the real ones, not
the TU58). Those
sometimes ended up in the laundry by accident and were none the worse
for wear. That tape is laminated, though; the oxide is under a mylar
cover layer.
Given that, why aren't other mylar magnetic media similarly laminated?
Expense?
