Good description, but for the record I think you need to reach back to 4480 to get 18 track. 4480 Cartridge Tape Subsystem This is the StorageTek IBM 3480-compatible tape subsystem, using 18-track format standard cartridges and is able to attach to parallel channels only. Silverton 4490 Cartridge Subsystem This is the StorageTek IBM 3490E-compatible tape subsystem, using 36-track format standard cartridges and is able to attach to parallel channels only. TimberLine 9490 Cartridge Tape Subsystem This is the StorageTek IBM 3490E-compatible tape subsystem, using 36-track format extended cartridges and with a performance twice that of the Silverton 4490 Cartridge Subsystem.
