I've scanned something called the "MPI Flexible Disk Drive Interfacing
Guide"
for the Model 51/52 floppy units
Is that the same as:

?
Q: Is the 91/92 being asked about merely a 96TPI version of the MPI
<snip>
In 1982, this Infoworld article shows MPI in on a standards group for
microfloppies. They were not a player with a lot of room to stumble,
and I believe they didn't do much with the 91/92 technology because of
lack of sales. They were betting on the 3 1/2" market, and will look
around to see if I can find info on that.
The following google scan barf is for Infoworld, September 13, 1982, page 6.

Lists members of a group to standardize form, as well as that there are
those working on a 3" media.
The 1982 time frame fits with our maintaining their Microdata system,
and worth mentioning we lost them as a customer for that due to their
business not going so well.
In Jan 1983, they bought for stock a head company
https://www.upi.com/Archives/1983/01/24/BUSINESS-BRIEFS/1727412232400/
"Micro Peripherals Inc. said Monday it has acquired in return for MPI
stock assets of the floppy disk magnetic recording head operations of
Information Magnetics Corp., a subsidiary of Computer & Communications
Technology Corp."
There isn't much in the trade press other than this I found.
