According to https://www.bitsavers.org/pdf/fujitsu/disk/FujitsuDriveList.txt as Pierre

M2284N 160MB 14" SMD
M2294N 330MB 14" SMD
M2298N 498MB 14" SMD
All are multi-platter drives, and all with way too _much_ capacity; the one on the photo
is only 25MB. It looks like a single-platter drive to me, and it doesn't much look
like the diagrams in B03P-4580-0100A_M228x_Apr81.pdf, even after ignoring the
multi-platter aspect. So I don't think that it's a Fujitsu.
It seems to me that it must be another manufacturer.
The VCF thread containing the image and context is here:

Can anyone identify the 14" HDD seen in the
following photo (not mine)?
It's unusual in that there are two moving heads on the top surface of
the platter. I presume that there's a fixed head on the bottom
surface for the clock track. This is from a Data General 6100 disc
subsystem which is advertised as 25MB capacity. There's a related
model with half that capacity.
It's a Fujitsu drive and has an SMD interface, but I don't know what model.
