Displaying and Reading Data: Finding Grooves

After an image has been produced a software algorithm finds the bottoms of the grooves and traces them in blue. The bottom of the groove is where playback stylus would have rested, and dictates the path the stylus would have taken around the cylinder. Therefor the data along the groove bottom is most important in producing audio.
