FACOM 6450 Mass Storage System

Completed in 1980, the FACOM 6450 was a mass storage system (MSS) from Fujitsu which used 50MB cartridge tapes as a secondary storage hierarchy. With the advancement of the information society, there was a strong need for a memory system enabling direct access and integrated management of large amounts of data. This system was developed to meet this need by introducing automatic warehousing of magnetic tape and the concept of a virtual disk. It thereby improved efficiency and reduced labor in data processing.
