WebRare Earth Magnet Recovery Machine for HDDs The electric motors in HDDs contain rare-earth magnets. These are called voice coil motors (VCMs). Fig. 2 shows the process used to separate and recover the rare-earth magnets. While development of an HDD dismantler(1) that removes VCMs from HDDs and demagnetizes them has already been … Web19 apr. 2011 · Because rare earths make such excellent magnets, researchers have put little effort since the early 1980s into improving them or developing other materials that could do the job.
