Line 63:
* Many 1985-2007 tapes duplicated on BASF cassettes have dark or silver ink prototype codes. Usually, these codes included the tape nominal length, the shift digits, the print date and/or the print time.
** Only on tapes duplicated at either CBS/Fox or Technicolor.
** Some Memorex-manufactured tapes also had BASF codes. It is possible that somewhere down the line, Memorex licensed the tapes to BASF months after the first manufacture date. Once again, only on tapes duplicated at CBS/Fox or Technicolor.
** 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.
