This process is "linear", rather than non-linear editing, as the nature of the tape-to-tape copying requires that all shots be laid out in the final edited order. Once a shot is on tape, nothing can be placed ahead of it without overwriting whatever is there already. (Such a replacement is sometimes called an "insert edit".) If absolutely necessary, material can be dubbed by copying the edited content onto another tape, however as each copy generation degrades the image cumulatively, this is not desirable.
