How Do I Stop My Discs from Sticking Together?

Q: I am a high school teacher and I run multiple copies of DVDs for the football coaches and for my TV Production class projects. It appears that [brand name deleted] discs seem to jam up our automated robotic feed duplicator. I have tried manually separating them and writing titles on them with felt tip markers PRIOR to duplication, hoping that this would cause them to stick together less, but nothing has helped.

Which type of discs would you recommend to solve this stickiness issue? Or is there a certain manufacturer or brand that you would recommend that stick together less than others?

A: First, I'll address the question about which disc you should buy. You should always try to use the brand of disc that was recommended by your equipment manufacturer. Some discs are thicker or heavier than others – the difference in size can be measured in microns, but it can affect your results. For example, we've learned that heavier discs usually perform better than lighter discs in gravity-fed printers.
