CD data pitch would be 700nm, and it seems that camera sensors have a pixel pitch at the same order of magnitude. Ignoring the lens resolution you'd need for a near 1 to 1 rendering at that size, any hand movement or misalignment would also be catastrophic. That sounds like a crazy dream until we get to sensor in the peta pixel range ? https://www.researchgate.net/figure/CD-DVD-Blu-ray-disc-data-pit-pitch-and-laser-spot-dimensions-14_fig4_326233880 https://www.researchgate.net/figure/CD-DVD-Blu-ray-disc-data... https://letmaik.github.io/pixelpitch/ https://letmaik.github.io/pixelpitch/
