DiscTrack Plus handles all media with pits and/or grooves, including masters, stampers, and replicas. It measures height and depth, width, length, and sidewall/endwall angles of every feature in an AFM scan. It measures individual and mean track pitch and track pitch variation. It analyzes land and effect (bump/pit) lengths, which affect electrical asymmetry. It measures variation in edge placement, a key component of jitter. And, DiscTrack Plus is the only method for directly measuring wobble amplitude, giving you peerless insight into speed control, crosstalk, and jitter problems.
