Abstract
Abstract An external storage device having racks for receiving cartridges each accommodating a storage medium therein, drive units capable of recording and reproducing data from the storage medium, a mechanism for transporting the cartridge, and a mechanism for loading the cartridge. A mechanical section and a control section are disposed in a rectangular parallelepiped housing and isolated from each other, except for a portion for ventilation, by a partition. An air inlet is formed in the housing adjacent to the mechanical section and provided with a filter and suction fans. An air outlet is formed in the housing adjacent to the control section and provided with an exhaust fan. The drive units and racks have substantially the same height and same width and are arranged face-to-face at both sides of the transport mechanism.
