The IBM 3850 mass storage system, announced in 1974, held up to 472G on strips of magnetic tape. The 3850 was a rectangular box large enough walk into, with the strips stored along its interior walls in a honeycomb arrangement of slots. A pair of robotic pickers took turns running along a set of rails where they would fetch a tape strip, carry it to a device that wrapped it around a drum for read/write access, and later return it to its slot. You could watch it operating through a window in the box (IBM loved to show off their stuff).
My point is that none of this is new. It is neither interesting nor innovative.
