Abstract :
AID Inc. has played an active role in the area of optical disc inspection since 1986, and has developed a series of systems for use with audio CD´s. With the advent of higher speed requirements in production technology, and the emergence of interest in video, WORM, and MO discs, AID has been developing systems that afford higher speeds, improved resolution, and better defect classification. In addition, AID has designed systems to meet new optical disc requirements, including bar code readers, catalog ID systems, and disc counters. The systems and their capabilities are described, as are the requirements that future systems will have to meet
