Magnitizdat

Magnitizdat (Russian: магнитиздат, lit. 'tape-recorded publishing') was the process of copying and distributing audio tape recordings that were not commercially available in the Soviet Union. It is analogous to samizdat, the method of disseminating written works that could not be officially published under Soviet political censorship. It is technically similar to bootleg recordings, except it has a political dimension not usually present in the latter term.
