Line 22:
* Most tapes duplicated at GTK Duplicating Co. were duplicated on cassettes manufactured in either Hong Kong, Korea or Taiwan, and had the audio track in linear only, although many SP-mode tapes duplicated at this arm 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 for about 45 seconds at the end.
* Some tapes have the recording tab intact
* Certain 1997-2005 tapes were duplicated on cassettes manufactured in Korea.
* All tapes have a printing with a letter with the nominal tape length, mostly above the tab part. Examples: M-15, A-30, H-45, W-15, T-30, K-45, etc.
