๐ฟ Optical Disk is one of the animated emoji in Google's Noto Emoji Animation set โ the same optical disk emoji (U+1F4BF) drawn as a short looping Lottie animation. Lottie files are vector, so the animation stays sharp at any size and is usually much lighter than a GIF or a video.
๐ฟ is the optical disk emoji, part of Unicode's Objects group, added in Emoji 0.6 (2010). Unicode's keyword list links it with โblu-rayโ, โcomputerโ, and โdvdโ.
