Derived from the original specification of a system having two spindles each with a disk capacity of 30 MB, Haughton is reported to have said: "If it's a 30-30, then it must be a Winchester" after the .30-30 Winchester rifle cartridge. The disks were 8 inches in diameter and had a capacity of 200K. The plague . [9] A single head assembly having two heads was used for access to all the platters, yielding an average access time of just under 1 second.
