Kevin Stephens:Very popular many years ago, painting green ink around the circumferential edge of CDs reputably helped to hold the laser light in and increase accuracy. Did they really work and does anyone still use them?
I greened my CD's because I proved to myself that it did indeed work.
Myself and a friend conducted blind listening tests with two identical CD's, one treated with green (Laserway) pen, the other left untreated. We could both pick out the treated CD without fail, every time! Sound quality was definitely improved.
I only used to treat the outer edge and not bother with the inner, as the paint would always wear off over time as the CD is placed on the hub.
I remember seeing an extreme case in the hi-fi press many years ago, someone had actually painted the whole of the inside of their Naim CD player's drawer compartment green!
BTW, the colour is green for treating CD because the colour of the laser that reads CD is red,
green is the negative colour of red!
If anyone can source somewhere to obtain these laserway green pens, please let it be known.
