We get our fair share of these, and it runs the gamut from poor erasure to actual gaps between recordings through which the previous recording appears, to RFI, to the 'recordist' who records a single quarter-track over the 'B' side of a full-track recording. Yes, I know. There's no 'B' side for full-track tapes. We do our best to represent what happened in the original object metadata and then describe them appropriately in the descriptive metadata.
Remedies for production masters depend upon the type of problem, but I believe the question was more about description.

>> As I've explained in this list before, I'm currently working with digitizing a number of amateur 1/4" reels from a student radio archive. Since much of the content produced is amateurly engineered, all too often the stock was reused tape. Along with this practice, one finds artifact fragments from previous generation recordings that run for anywhere between a couple seconds to a few minutes. I am wondering if there is a proper name for these fragments. Internally, I have been using the word "ghosts" to describe these fragments but I was wondering if there was a more established name.
