Temperature of Material as a Mechanism for Stored Data |
Is there any practical way data could be stored and retrieved in the
form of a material heated to a given temperature? I envision many small
quantities of the material.

Thermal conductivity. Blackbody radiation. No.

Not to mention that it's a heck of a lot simpler to use magnetic
domains like most disk drives do now. What would be the advantages
of using "hot spots"? I sure don't see any.

Well yes, it could be stored this way. But it wouldn't ne practical,
since all the little bit storage units would at all times be tending to
exchange heat with their surroundings. And the smaller they get, the
faster they'll make the trade due to their tiny surface areas. To
maintain all their respective temperatures, or at least their
temperature differences, you'd need some system for monitoring the
temperature field of the storage device, and then pumping heat in & out
of them selectively. Essentially it'd require that the information be
kept somewhere else to begin with so that the system would know what
the temperature distribution ought to be, so you'd need another
entirely different storage method, rendering the temperature based
memory moot.

If your storage array were close to absolute zero, quanta of heat energy
might be a way to store data. However electrons are easier to move around.

Yes, I agree.
