My friends, stop now if you intend using aftermarket labels for you CD/DVD's. The likelyhood of having glitches resulting in stop and start scenarios or just stopping that won't continue is almost a given sooner or later. Let me give you the scientic analyses so what I tell you will make sense.
We all learned in high school that everything expands or contracts with heat and cold. In essence this is what happens on your cd/dvd discs. More than likely you will burn a disc which gets very warm and as soon as it comes out of the oven you slap on a room tempeture label. Having spoken to a major label manufacturer, I was informed that the adhesive used is permanent adhesive, which is why it is such a difficult job to remove them after applied.
Back to the science. So what happens after the disk comes out of the burner and the label is affixed immediately? Here's your answer; As the disc cools down, the room temperature lable doesn't want to move because the permanent adhesive is holding tight. The end result is a very slight warpping to the outter portion of the disc. This warpage is undetectible by the human eye and can only be seen by spinning the disc in a controlled experiment. This translates into problems that more frequently happen after you get through the 1st half of your music or movie, and yes it will effect music cds.
The last contributing element in the science of aftermarket labels is relative humidity. To be brief, when you consider a laser that is heating up your disc everytime you put it in the player/burner and then slap on the room tempeture label and lastly add the humidity facor which gives the lable better or worse expansion and contraction capabilities, you now have (3) things working against you.
For those of you that are not having problems, you must have environments that are compatible with label making or pehaps you let your discs cool before applying the labels. Even if you let them cool, the disc and the label don't expand and contract at the same rate. Afterall one is plasic and one is paper!!! The longer the labels are affixed, the greater chance for failure. As the glue cures over several months, it continues tugging at the disc and when you play it, the intense heat of the laser begins to expland the plastic while the label & adhessive want to hold it firm. This causes the slight outter disc warpage resulting in wobble and ultimately glitching and stopping.
Hope this saves somebody a bunch of label removing that might have OCLMS (obsessive compulsive label making syndrome.)
