@ fender62,
VCR VHS cassettes use magnetic tape, which is susceptible to emf (electro magnetic force), which many electrical devices create when in use. In short you have the potential to “erase” the data that is recorded on your VCR VHS cassettes if your VCR VHS player/recorder is placed in close proximity other electrical components.
Suggest referring to your VCR VHS player/recorder user/operation manual and look for the “Avoid Strong Magnetic Fields” warning.
I have know individuals who have placed VCR VHS cassette tape on top of their television for a short period and have found the tape destroyed by emf artifact “erasures”.
