Hi. Having recently been the happy recipient of an HP 7978 tape drive I have set about the task of finding new blank tapes for it. Not too difficult until faced with the embarrassing question of whether my tapes need to be Wright Line seal or Easy Load (Auto Load ?). My vintage magnetic media experience doesn't go much beyond 8 inch disks, so I wondered if anyone could please give me some hints on how to answer this. (Of course I haven't got any manuals). Thanks in advance.
