The IBM 1301 Disk Storage Unit,[10] announced in 1961, introduced the usage of heads having self-acting air bearings (self-flying heads) with one head per each surface of the disks. * Some observers have noted that the 3340 was known as "Winchester" because its development engineers called it a "30-30" (its two spindles each had a disk capacity of 30 megabytes), the common name of a rifle manufactured by the Winchester Company. In 1964, the IBM 2311 was the first standardized disk drive, which could be used across multiple versions of the System/360 computer.
