- Floppy disks have been formally deemed out of date in 2010, but persevered in shocking locations for years
- Polymatt used CNC machining and PET movie to craft a functioning magnetic storage disk
- Iron oxide coating allowed the handmade disk to retailer and retrieve primary magnetic knowledge
Floppy disks, as soon as a staple of non-public {and professional} computing, have been phased out for over a decade – however whereas the know-how was formally declared out of date in 2010, some organizations stored utilizing it surprisingly lengthy.
The Japanese authorities solely moved away from the format in 2024, whereas the German Navy adopted swimsuit the identical 12 months. In the USA, the final official use of 8-inch floppy disks for nuclear launch coordination led to 2019, with San Franciso’s authorities additionally lastly chopping ties with floppies in 2024.
In opposition to this backdrop of obsolescence, a YouTuber often known as polymatt determined to recreate one from scratch, utilizing trendy instruments and consumer-grade tools.
Engineering a working floppy from the bottom up
Polymatt started the venture by rigorously measuring and modeling the disk enclosure and inside parts utilizing Shapr3D and MakeraCAM software program.
He then minimize aluminum components with a Carvera Air CNC machine, guaranteeing exact tolerances for the mechanical construction.
For the magnetic disk floor, he laser-cut PET movie and coated it with a suspension of iron oxide powder, replicating the fabric properties wanted for magnetic knowledge storage.
After assembling the parts, he managed to magnetize the disk and write to it.
Whereas the info dealing with capabilities have been primary, the truth that a functioning magnetic storage medium emerged from uncooked supplies marked a notable technical achievement.
The method was not with out difficulties, however persistence and methodical experimentation allowed him to finish the construct.
SSDs ship high-speed and sturdy storage in compact codecs, whereas an exterior SSD presents transportable capability far exceeding what was as soon as potential with floppy disks.
A single trendy SSD can retailer thousands and thousands of occasions extra knowledge than the recreated floppy, with speeds that make the older medium appear impractically gradual by comparability.
Whereas polymatt’s recreation is unlikely for use in sensible purposes, it demonstrates the enduring attraction of hands-on engineering initiatives.
Constructing a floppy disk in 2025 serves extra as a tribute to a pivotal period in computing than as a viable different to present storage strategies.
For individuals who as soon as relied on them, the acquainted clunk of a floppy drive studying knowledge is a part of a technological heritage that formed trendy computing.
