Yes, there was such a format for a brief period of time. This format was
pioneered by Dysan (are they even around anymore?). It came out in 1983
(same as the Sony 3.5" and the Hitachi 3"), but never took off. As far
as I know, there was no computer that ever used this format. However,
Apple was considering using it for the Macintosh, but (thankfully for
us) saw the light of day & decided to use the Sony 3.5" (they must have
had bad memories over the "Twiggy" debacle!). If you're looking for
technical data (tracks/sectors, formatted free space, etc.), try a
search engine (search.com).
