These solutions won't help with DDR. DDR wil anyhow overwrite the label -if any- on all but the first tapes (keeping the label of the first tape means you must position beyond it before starting DDR). You'd need a DDR with tape label support, IIRC, there was a post here some time ago with the DDR modifs required to do so.
