Every CD holds its data as a continuous spiral of microscopic dents called pits, with flat areas known as lands in between. Each pit measures about one thousandth the width of a human hair. A CD player reads these by shining a laser onto the surface. Light reflects differently off pits and lands, and those tiny changes in brightness are converted into binary code. That is how sound, video, or files become readable data. Love technology? Follow @Technology Credits: @microscopie_44 #technology #sc

Trending hub !!! on Instagram: "Data on a CD is stored as a long spiral of tiny dents called pits, and the flat areas between them are called lands. Imagine the surface like a very fine spiral groove going from the center outward, similar to how vinyl records have grooves. Each pit is microscopic, around one thousandth the width of a human hair. They don’t directly represent ones and zeros. What actually matters is the change from a pit to a land or from a land to a pit. When a CD player shines
