iTnews gets a storage history lesson at the HDS' Disk Array Systems Division at Odawara, about 45 minutes south of Tokyo by shinkansen (bullet train). The gallery shows off a potted history of magnetic disk drives made at the nearby manufacturing facility.

An Hitachi H-8564 magnetic disk drive unit. According to the Information Processing Society of Japan (IPSJ - http://museum.ipsj.or.jp/en/), it was built for the HITAC 8000 Series mainframe.
The IPSJ said the unit had a memory capacity of 7.25 Megabytes. The first customer unit of the H-8564 shipped in 1967.
