I don't think so, if it works as for the HD I read that "a degaussed drive is inoperable in any system. The magnetic erasure rearranges the magnetic field to such an extent that standard read heads are unable to find a magnetic reference point for tracking.", so that "a degaussed disk cannot be used after degaussing".
