Kryoflux
Flux-level disk preservation
A USB-based floppy disk controller that captures raw magnetic flux transitions, enabling preservation of copy-protected and deteriorating disks that standard methods cannot read.
Overview
Kryoflux is a USB-based floppy disk controller designed for preservation. Unlike standard disk controllers that read formatted data, Kryoflux captures raw magnetic flux transitions, preserving copy-protected disks and recovering data from deteriorating media that would otherwise be lost.
Fast Facts

How It Works
| Standard Controllers | Kryoflux |
|---|---|
| Read formatted sectors | Capture raw flux |
| Fail on protection | Preserve protection |
| Binary data only | Timing information |
| Skip bad sectors | Capture everything |
Key Capabilities
| Capability | Benefit |
|---|---|
| Flux capture | Raw magnetic transitions |
| Copy protection | Preserves timing-based schemes |
| Weak sectors | Multiple reads for recovery |
| Various formats | Amiga, PC, C64, many others |
Preservation Applications
| Use | Value |
|---|---|
| Protected games | Preserve with protection intact |
| Deteriorating media | Rescue before loss |
| Archival | Complete flux record |
| Analysis | Study protection schemes |
Supported Systems
Kryoflux reads disks from:
- Amiga (880KB, HD)
- PC (360KB, 720KB, 1.44MB)
- C64/128 (1541, 1571)
- Atari ST
- Many others
Output Formats
| Format | Use |
|---|---|
