Chuck, I don't know if we are talking about different things? You are speaking about a 3 Mode drive that allows 1.2MB on 3.5" drives. I am asking about a Tri Density (as in SD, HD, ED, TD) drive. Supposedly these drives were going to use longitudinal recording (vs. the perpendicular recording used in ED drives) to fit 12.5MB on a 3.5" disk. I had linked a press release in the OP: www-computerwoche-de.translate.goog/a/hitachi-maxell-bietet-nec-neue-12-5-mb-floppy-an,1155888?_x_tr_sl=de&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp I always thought the Mode 3 drives recorder 1.2MB on a standard 1.44MB floppy (kind of like how QD drives recorded 720KB on a 1.2MB disk). The drives were going to be called: PC FD810.1. Doing a Google search bring up some pictures of disks so maybe the drives did make it out in Japan? https://auctions.c.yimg.jp/images.auctions.yahoo.co.jp/image/dr000/auc0312/users/4f92de2852282d0c4055f15836cd43f760275f36/i-img1200x675-1672137143s8ehmb271085.jpg Or am I missing something? -Ali
