The laser that reads and writes data in a DVD recorder focuses through an optical lens. Dirt and dust that gets onto the optical lens can cause it to cloud and become unusable. Replace the optical lens inside of a DVD recorder to restore the player's capabilities. A few household tools are required, as is a replacement optical lens from a laser supply shop. No electrical skills are needed to accomplish the replacement.
