After recording -- Write only on the center hub of the DVD-R media or symmetric DVD-R label with a soft marker. Never use a hard point pen on the DVD-R. Do not use small stickers which can cause imbalance. Non-acrylic glue can damage the media. Clean with a soft, dry cloth and store at room temperature away from direct sunlight.
The most consistent and reliable part of your DVD recording is the DVD-R media.
