For the platter, you'd need a substrate with the ferromagnetic material applied – I'm not sure what process is involved here, electroplating, coating? Some equipment might be borrowed from the tape manufacturing process if that is not considered cheating.

- ChuckMcM 10y agoI'd go with a spin coating, easiest to create. However coming up with a material that could be easily spin coated that would be a bit harder. There is a lot of math involved [1] :-). There was an excellent "Secret Life of Machines"[2] video about tape which made magnetic tape by sprinkling ferrous oxide (rust) over "sticky tape" (which in the US is often called 'Scotch Tape' as that is the dominant brand).

- ricksplat 10y agoScotch tape is something slightly different to what I'd consider "sticky tape", which is what I'd also know as Sellotape. We have Scotch tape here as well (W. European seaboard ;) but it's a neater more refined (cloudy) tape specifically used for paper, whereas Sellotape is a more general purpose clear tape.
