Hi,
yes, thats the audio side of it,
but the laser received signal has a much higher capability.
However i think that the laser is read and recorded
differently on PC CDs and VCDs than it is for audio.
And i think the latest DVDs have multiple laser heads.
You would have to get into the circuitry at quite a basic
level, and re build the signal amplifying circuitry.
You might be able to leave the existing laser steering
mechanisms in place.
It would be very involved.
