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. http://www.boulder.nist.gov/div816/2001/MagneticRecordingMeasurements/ 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: http://www.usbyte.com/common/AFM_storage.htm 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.
