For archiving a very old floppy, you don't want to touch the surface if you can help it to avoid causing any additional wear.

- anfractuosity 2y agoHave you come across any ways to achieve that out of interest?
- chiph 2y agoKryoflux had special drives for preservation but I don't see them in their store anymore. So no, sorry.
- rasz 2y agoSpecial in what way? The most special thing about Kryoflux was their EULA claiming _every bit of data imaged with Kryoflux hardware belongs to Kryoflux_ https://www.reddit.com/r/vintagecomputing/comments/buyj9f/til_that_computer_archivists_image_the_magnetic/epjwsut/ https://www.reddit.com/r/vintagecomputing/comments/buyj9f/ti...

- asdefghyk 2y agoA possibel way, I have not read the paper yet. Found this promising material https://www.researchgate.net/publication/371624900_The_do-it-yourself_approach_of_developing_a_magnetic_field_mapping_setup_using_3D_printer/link/65365a331d6e8a707046c8d7/download https://www.researchgate.net/publication/371624900_The_do-it... Found via google search with words >>DIY 3d printer Floppy Disk, MAgnetic flux<< ( I understand it would produce massive amounts of data, since it is recording the analogue value of the magnetic flux level readings. )
- anfractuosity 2y agoThanks a lot, will have a look, that sounds very interesting!
- rasz 2y agoLooks like this would require ?3? orders of magnitude higher resolution to start resolving data on floppies. Least dense DD disk is ~6000 bits per inch, ~240 bits per mm.
