Description
In 1981, Fujitsu entered the OEM market for 10.5-inch disks with a product (called the Eagle Series) based on the FACOM 6421 Magnetic Disk Unit (completed in 1981) which was the first in the world to use 10.5-inch media. The M2351A (Eagle-1), with a memory capacity of 474.2Mbyte, was completed as the Series' first product in March 1982. At the time, the industry standard disk size was 14-inches, but with the Eagle Series, Fujitsu led its competitors in using small diameter 10.5-inch media and adopting the new concept of a disk enclosure structure. With this Series, Fujitsu built an excellent position in the OEM market for high-performance, high-capacity magnetic disks.
