Bob Niland, Widescreen Review, Laserdisc Magic, 1998: “Laser rot is the appearance of video and audio artifacts during the playback of Laserdiscs, and their progressive worsening over time. It is most commonly attributed to oxidation in the aluminum layers by poor quality adhesives used to bond the disc halves together. Laser rot was indicated by the appearance of multi-colored speckles appearing in the video output of a laserdisc during playback. The speckles increased in volume and frequency as the disc continued to degrade. Much of the early production run of MCA DiscoVision Discs had severe laser rot. Also, in the 1990s, LaserDiscs manufactured by Sony’s DADC plant in Terre Haute, Indiana were plagued by laser rot.”
