Bill, no serious need to degauss or magnetically erase used tapes IMHO. Back in the day this might have been a more effective approach to repurposing reused tape stock. I’m not so sure that blanking/blacking or repacking are all that necessary.
As much out of habit as anything I do use my fast forward & rewind device to “repack” my new MiniDV tape stock before first use just to shake out loose particles and cleanly rewind tape that sometimes shifts a bit during storage and shipping.
People wanting to acquire and learn how to properly use a degausser can check out MarkerTek and perhaps even B&H Photo Video.
