I read "Notes on Floppy Disks" <https://extrapages.de/archives/20190102-Floppy-notes.html> https://extrapages.de/archives/20190102-Floppy-notes.html> last night. It, along with this, really makes the technology seem much more accessible to a non-electronics professional like me. These help make the various floppy emulator devices I've got for my retro-computing habits seem more understandable. (It also really makes me want to build some electronics skills, too!)
- blattimwind 8y agoMagnetic recording is kinda fascinating because it is conceptually simple but very hard to do well. Conceptually all you need for a tape machine is two small write coils (erase+write) and the bias oscillator. In practice the "small coils" are complex precision parts. The circuitry of a Nagra is fairly straightforward to replicate, but building comparable tape heads in your workshop will take years.
