According to https://www.bitsavers.org/pdf/fujitsu/disk/FujitsuDriveList.txt as Pierre notes it would then have to be one of these three: 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.
