Fascinating video of what a CD looks like when magnified! 💿 Once zoomed in, it's easier to see the CD data represented as tiny indentations known as pits, encoded in a spiral track moulded into the top of the polycarbonate layer. The empty areas between pits are known as lands. The laser reading the disc interprets these pits and lands as 1's and 0's. 1's and 0's = digital data This data is processed and output to your speakers as digital audio perfection. 👍 Video source: @macrofying on Instag

Each CD stores information in a single, unbroken spiral made up of microscopic dents known as pits, separated by flat areas called lands. Every pit is incredibly small—about one-thousandth the width of a human hair. When a CD player shines a laser onto the disc’s surface, the light reflects differently off the pits and lands. These subtle variations in reflection are then translated into binary code—the digital language that allows sound, video, and other files to be read and played back. #indot
