Could be.  It sounds a bit like the Drivetec drives of the same time
period.  Something like (ISTR) 192 tpi, using an embedded servo,
making factory-formatted disks mandatory, something that probably did
more to kill the drive than anything else.  I've still got a couple
of the Kodak/Drivetecs with media from Dysan, but basically they
exist for the eventuality that someone, somewhere has data written on
one of these that they need to get at.
