How to Tell

 * Most tapes duplicated by GTK Duplicating Co. were duplicated on cassettes manufactured in either Hong Kong or Taiwan, and had the audio track duplicated in linear only. Many SP mode tapes, though, did have a hi-fi audio track in addition to a linear track.
 * Post-1986 tapes have a black screen test pattern with the 1000 Hz tone at the end.
 * Pre-1998 tapes have the record tab intact, while post-1998 tapes omitted it.
 * Certain 1997-2005 tapes were duplicated on cassettes manufactured in Korea.
