I'd love to see what could be done with current tape storage technology in standard compact cassette format.
There's some space occupied by the servo tracks (which align the heads to the tap) in LTO, but if we ignore that...
Current-generation LTO9 has 1035m of 12.65mm wide tape, for 18TB of storage. That's approximately 13.1m², or just under 1.4TB/m².
A 90 minute audio cassette has around 90m of 6.4mm wide tape, or 0.576m². At the same density it could potentially hold 825GB.
DDS (which was data tape in a similar form factor) achieved 160GB in 2009, although there's a lot more tape in one of those cartridges (153m).
Honestly, you'd be better off using the LTO. Because they're single-reel cartridges (the 2nd is inside the drive), they can pack a lot more tape into the same volume.
