Written by the CircuitScope research team in our own words, from the sources listed at the end, and checked by our moderators.

Disc read errors on the Wii and Wii U are usually caused by a dirty or scratched disc, or a worn laser in the drive. Rule out the disc, positioning and software first; on the Wii, most persistent disc read errors are fixed by replacing the laser (lens) assembly inside the drive.
