It really is nothing more than a degausser as I have long suspected. Just the application is different from, say, erasing a tape. I have been using a hand held degausser for the past 15 years for similar effect.
The damn things actually works on LPs too. This leads me believe the mechanism has more to do with the plastics than any physical change in the metallized data layer. Perhaps there is a lessening of the polarization effects of the laser penetrating through the clear plastic. I suspect, in the case of LP's, the effect literally scrambles the polar molecules which will eventually slowly align themselves in a similar manner as the heat of the stylus momentarily melts the medium in the presence of the magnetic field of the cartridge. Certainly the manifestation of this is the lessening of the static charge.
Considering that the laser also emits a lot of heat and that most CD players use a magnetic chuck and have the presense of a motor very close by, conceivably the plastic may slowly reorient itself too. In my experience, the effect works for only one play! Pushing repeat negates and erases the effect.
Pure speculation on my part as to the causality, as I have no means of measuring these effects.As usual YMMV
