I worked as a projectionist for a few years so in learning how sound is read off the film itself, I always assumed this is a phenomenon related to the fact that film is stored in rolls (same for VHS and cassette tapes), but what exactly is happening? Does sound from another part of the reel transfer due to the fact that the film touches? Maybe I’m way off, but I can’t for the life of me ask the right question to get an answer anywhere.

It’s called “print through,” and it’s why analog recording studios store tape “tails out.”
By storing tape backwards rather than ready to play, the print through causes a more natural, harder to detect echo rather than a pre-delay.
