Summary from en: wiki[edit]

An audio CD of mine. Portion shown is the innermost, as such would doubtless be the intro to the first track. Taken with a Sony T-33 zoomed in about 2X, held up to the 10X eyepiece of a microscope using the 100X lens (100X total, 10X). The CD was placed directly on the microscope, and illuminated from the side with a very small bright-white LED.

The pits in a CD are 500nm wide, between 830nm and 3000nm long and 150nm deep.

The total track width, including pits and space between, is 1600nm between intervals.
