Yes. See also https://en.wikipedia.org/wiki/IBM_2321_Data_Cell . By the
standards of the time it was an unusually high capacity storage device, way
faster than a room full of tapes and much larger than the 2311 disk drive.
While on the topic of odd IBM mass storage systems, does anyone recall
an IBM system that used rotating carousels holding sheets of magnetic
material? The carousel would rotate to position the selected sheet into
the read/write station, where it would be moved up and down relative to
the multiple fixed heads, a weird linear riff on a fixed head disk.
LBL had one of these systems, installed in the same room as one of the
few examples of the IBM 1360 photo digital storage system. They kept a
broom next to the later in order to sweep up the photo chips when the
thing occasionally spewed them everywhere.
