D-Skin protective disc covers: Every library in the country should get a supply of these for their DVD collections, which are, invariably, the most scratched up set of media in existance.
They are clear plastic covers that clip onto your CD/DVDs and protect them from being scratched or smudged. They can be left on at all times and don’t affect playback while protecting your discs. They add hardly any bulk, which means they will work with both slot-loading or tray-loading drives. I tried them on my DVD player and in my car and everything worked without a hitch. The only problem I ran across was when I tried using covered discs in my iBook. Things felt a little too snug with the covers, so I didn’t push them all the way in and risk them getting stuck.
