IBM TotalStorage™ 3490E Tape Drive

z/VSE supports IBM® 3490E tape drive devices. The IBM 3490E with its control unit Models A10/20 (including B20/B40), D41/42, and C10/C11/C22 is a double-density follow-on device to the IBM 3480/3490 tape subsystem. The models of the IBM 3490E have a standard cartridge capacity of up to 1200MB/400MB (with or without compaction through the IDRC feature). The cartridge capacity with the IDRC feature installed is dependent on the compaction ratio. All models of the IBM 3490E can read IBM 3480/3490 cartridges but not vice versa.
