I'm going to buy MZ-NH1 but I'd like to know if it is able to record on old MD media (74 and 80) so I can use this media in my other equipment (NetMD and MDLP decks). On minidisc.org there is that it is possible to record only when older media is reformated, but regarding to local seller I need to reformat it only if I want to record with new HiMD format. Could someone explain it to me, or direct me to some official source to confirm this ? Thanks.
