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

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

Interesting Tech Videos!🎬 on Instagram: "Under a microscope, a simple CD reveals an intricate world of microscopic ridges and pits, transforming from an ordinary disc into a stunning digital landscape. Each of these tiny indentations carries precise information, arranged in a single spiral track that stretches more than five kilometers across the disc’s surface. When a laser scans this track, light reflects differently off each pit and flat area. These subtle variations are then read as binary

🇬🇧 CD-ROMs, DVDs and Blu-rays are coded in binary, 0 and 1, thanks to alternating of pits and bumps on a metalized or plastic surface. First, I separated the two plastic layers to access the metal part. Otherwise, it is impossible to focus under the microscope. Then I show the comparison between the size of a hair (diameter approx. 80µm = 0.08 mm) and the etching data on the DVD. The smallest pits are 0.4µm, i.e. 200x smaller than a hair. The data from the DVD is read on the surface of the dis
