When working with retro computers, you sooner or stumble upon aged disk media. Unfortunately data is lost. Various solution exists such as gotek, C64FC or custom hacks.
However, when encountering old, unreadable disks, there is still hope. The problem is that magnetization is lost over time, but by measuring it at greater accuracy, it is possible to retrieve and recreate the information.
One such solution is the KryoFlux floppy controller.
KryoFlux is a USB-based device designed specifically for the reliability and precision needed to acquire reliable low-level reads suitable for software preservation. This is the official hardware developed by The Software Preservation Society, an authority in authentic floppy disk imaging and preservation.
