Never seen physically a 0.85" microdrive, or the Imation thingy, but I am familiar with the "normal" 1" IBM/Hitachi microdrive, they were at the time great little devices, not very "obscure", as a matter of fact relatively common. A blast from the past, one of them was used as mass storeage device on the original Matchbox WebServer: https://web.archive.org/web/20020601033615/http://wearables.stanford.edu/ https://web.archive.org/web/20020601033615/http://wearables.... I still have somewhere a couple of these ones: https://www.memoryc.com/externalharddrives/tone5gbusb2microdrive.html https://www.memoryc.com/externalharddrives/tone5gbusb2microd... there is a 5 Gb Microdrive inside, with a USB bridge. The 0.85" one was made by Toshiba: https://web.archive.org/web/20060206172031/http://sdd.toshiba.com/main.aspx?Path=8182000000070000000100006598000026b9/818200000b00000000010000659c000026ae https://web.archive.org/web/20060206172031/http://sdd.toshib... Incredibly the Imation Microdrive brochure can still be found: http://www.officeessentials.com/pdf/BR_MicroHD.pdf http://www.officeessentials.com/pdf/BR_MicroHD.pdf it was IMHO a very clever design.
