Inside a compact disc lies a hidden world of microscopic engineering. 💿 Data is stored as tiny pits and lands arranged in a spiral. A focused laser — thinner than a strand of hair — reads those bumps by detecting how light reflects differently off each surface. Each reflection translates into binary 0s and 1s, which are then decoded back into the music or data we see and hear. It’s a perfect example of how physics and precision engineering made digital music possible. - #science #technology #cd
