You should use special splicing tape, e.g. EMTEC (BASF) PW 384. Overtime, regular adhesive tape get smudgy (glue coming off...) The colour of the leader tape indicates the tape speed (DIN/IEC standards): blue = 7.5 ips mono blue/white = 7.5 ips stereo red = 15 ips mono red/white = 15 ips stereo red/white/black = 15 ips stereo with noise reduction yellow = end of tape Studio (broadcast) tape machines have optical detector for speed and noise reduction...

More specifically, once the transfer is done, is it ok to leave said tape on the reels as they are placed back into storage? Would this kind of tape off-gas or otherwise breakdown chemically over time in such a way as to have more deleterious effects on these precious reels than some kind of special splicing tape, and if so where might I acquire some? (I bought the leader tape off of e-bay for 20 bucks for 1500 ft of Scotch (3M) Leader Tape. Thanks for your help. Best, Brian Levy (currently:) Archiving Consultant to the Cherokee Heritage Center
