That looks like a RAMAC to me. Was its number
"1301" ?
A disk drive with up to 3 heads on seperate 'robots' accessing
the disks. It was manufactured from 1961 until 1970, for the
IBM 1410, 7070, 7074 and some other large IBM systems at this
time. Up to 5 units could be controled by one system and each
unit could be shared between two systems - the desity was
dependant on the host system ... basicly it was the follow
up to the RAMAC system, as a general solution.
IIRC the RAMAC cas was smaler and had complete transparent doors.
