Alpha CD Digital

Spanish CD manufacturer active from 1999 until 2003. Currently defunct. The polycarbonate plastic used by the company to manufacture CDs was highly prone to warping in warm conditions, as can occur while a CD is playing in a computer drive. This warping can cause read errors in some CD players, especially on tracks located near the disc's outside edge. This poor manufacturing process was not uncommon, as can be seen by other defects such as scratches on CD's and wrinkles on inserts.
