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
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
