I've noticed that the diet commonly preferred by trolls includes made-up
jargon, insults, and paradoxes. Responding with reason or legitimate
information leaves them craving more.

OK. Perhaps they *can* be scanned with lasers. However, as far as I can tell,
most companies actually recovering data from magnetic media are using some
variant on a magnetic sensor, not a laser.

See the section "New Technique for Recovering Data":
"Termed "second-harmonic magnetoresistive microscopy" (SH-MRM), this technique
makes use of high-resolution magnetic sensors developed for modern computer
hard-disk drives."
So as of 2 years ago, the research in the field was still using magnetic based
techniques, and of course the companies doing it for a living will be lagging
somewhat behind that.
Perhaps your confusion is based on a misunderstanding of the process:

Yes, a small laser is used - to measure the deflection of a sensor by a
magnetic field.
And I'm sorry that you find it unprofessional to be asked what your postings
have of interest *TO THE IETF*. The 'I' stands for 'Internet'. Not nuclear
weapon, not nanotech, not disk storage, but *INTERNET*. Unless you can show
how nuclear weapons, nanotech, disk storage, or whatever your next missive is
about is related *TO THE INTERNET*, it's off-topic for *THIS* list.
