DVD's and fingerprints: not a good match

Have you ever owned a DVD disc, or CD for that matter, that stopped working after a time? "It worked before, but now it doesn't," you say, "and my player still works fine with my other discs."

We receive a lot of calls from individuals that experience this type of problem and they want us to fix their disc. Our first response is a question back to them, "are there a lot of fingerprints on the back side of the disc?" The usual response is in the affirmative.

You see, contrary to popular belief, a disc is not an indestrucable, error-free form of digital media. All discs need to be free of dust, scratches, fingerprints, peanut-butter and the like in order to work correctly (lasers in the players need to read the information contained on the disc and obstructions prevent them from being read correctly). Burnable, duplicated, and home-media can be more suseptible to errors than factory replicated discs if they are not treated with respect.

This is generally as easy problem to remedy-clean the disc of fingerprints and nine times out of ten this will resolve the issue. Cleaning is a matter of using a disc cleaning solution (usually found in your local electronics store) and essentially wiping the fingerprints away. The motion to follow is NOT one of rubbing in concentric circles like waxing a car, but rather a straight line from the inner hole to the outer edge. Simple! One word of caution-only use wipes only designated for this application. Wipes that are made of wood products (tissue, toilet-paper, kitchen wipes, etc.), can actually scratch the disc and should be avoided!

Scratches, on the other hand, are something completely different. That, however, is a topic for another post (BTW-this is a huge problem with rental discs).

God's peace,

Chris.
