And I got a few emails directly asking about laser floppies.
So: floptical (optical floppy, laser guided), HAMR (heat assisted magnetic recording, laser heated), and LAMER (laser assisted magnetic erosion recording)
Floptical is laser guided floppy disks that use tiny tiny “cells”. They can reach over a GB of storage.
Hammer uses heat to expand the writing point, which cools and is read by a separate read head or a second head unit 40TB disks can be found today but the idea of exobytes isn’t fantasy.
LAMER is a WORM tech, write once read many. A laser literally burns off the coating of iron carbon cobalt from the disk. Test release units start at 20TB up to 100TB. The capacity is literally unlimited. The size, angle and power of the laser determines sector size and the smaller the frequency reflection the more data you can store. Test units are 2-18nm. Likely the next gen of non-portable removable storage. It’s direct competition is single write LTO tape.
