YouTuber recreates a floppy disk from scratch

In this article, the author discusses how a YouTuber, polymatt, set out to create a floppy disk drive from scratch. Floppy disks were once a popular storage medium, but they have become obsolete in recent years. The article describes how polymatt used various tools and techniques, such as Shapr3D, MakeraCAM, and a Carvera Air CNC machine, to measure and recreate the disk enclosure and other components. The magnetic disk itself was made by laser-cutting a piece of PET film and coating it with a suspension of iron oxide powder. After assembling all the components, polymatt was able to magnetize the floppy disk and write to it, albeit at a very basic level. The article also provides a brief history of the floppy disk, noting that it was declared dead in 2010 and that even the Japanese government and the German Navy have since abandoned the format. The author suggests that polymatt's project was a "wonderful dive into nostalgic tech and engineering prowess" and wonders if he might consider making a compact disc from scratch next.
