A couple of months ago, we told you about the Acorn Preservation Team, who are working to preserve the data from old discs before the data's gone forever.
 
Chris Evans and Phil Pemberton have written an in-depth look at how they were able to recover the data from some damaged discs that were otherwise unreadable using more traditional methods.
 
The post is an interesting look at how even when it appears the disc may be unrecoverable, with the right tools there can still be hope of recovering the data using more analogue methods at the magnetic flux level (and sometimes drawing peaks on a waveform manually!).
 
Also, as we noted in the previous article, the Acorn Preservation Team are still looking to help preserve any unique, rare, interesting and potentially historic discs anyone may have tucked away in the back of their cupboards before it's too late. They're not only working on BBC Micro discs, but discs for other formats and systems, too.
