Hi,
I just found this odd-looking device on ebay.de and it seems like it is some kind of giant floppy disk, but originally intended for audio.
Anyone has experience with this, or similar devices?
1 - What is it?
2 - How does it work?
3 - Could it in theory be used/hacked into an external storage device for the Arduino?
Idea: Control play/stop/record using with digital outs. Use Manchester encoding to read/write data.
Only a couple of hours left on the auction, so early input is appreciated.
Thanks in advance!/Anders
