TDK SA was a "work-horse" of type II cassettes. It was the most successful TDK cassette ever. It offered oustanding performance for reasonable price - a deadly combination for the competitors. The formulation is based on Super Avilyn particle - the TDK answer to chrome based type II cassettes. It appreared first around 1974.
