Tom's Hardware is reporting on a project by Cambridge University to rescue data trapped on old floppy disks [tomshardware.com]. Magnetic media only lasts a decade or so under optimal, climate controlled storage conditions. So this task is much more fundamental than just pushing the old disks into off-the-shelf drives.

Led by the library’s digital preservation team, the project aims to document and formalize best practices for floppy disk recovery, encompassing cleaning and handling methods, as well as imaging workloads. It’s also pulling in expertise from the retro-computing community, whose trial-and-error techniques are often the only reason legacy formats still survive.

You can forget those cheap USB floppy drives you can buy online. Cambridge’s preservationists don’t just mount disks and hope for the best; they sample the raw magnetic signal itself. Specialized hardware, such as the KryoFlux and open-hardware Greaseweazle interfaces, captures the flux transitions — the tiny changes in polarity that encode data — and reconstructs the file structure later in software. This flux-level imaging process enables archivists to recover non-PC formats and identify weak or damaged sectors that would otherwise remain unread.

This project only addresses the matter of hardware, so far. Although that is important on its own when working for preservation, much of the data will turn out to be trapped in proprietary or DRM'd formats. Thus draconian copyright laws can impose an unnecessary non-technical barrier to the final steps of legally retrieving the data and bringing it to a usable form.
