Tape manufacturers: Difference between revisions

* Many 1987-2007 tapes duplicated on BASF cassettes have dark ink codes. Usually, these codes included the tape nominal length, the shift digits, the print date and/or the print time.

** For example, if the dark ink code reads "T-82 M3" on top and "012393 S 1223", or "012393 S", that means the cassette is a T-82 length and that the tape was manufactured on January 23, 1993. The time code would mean 12:23 PM, and S and M3 would be two of the shift digits.
