Photo: 9840
Size: 4.3" W x 4.9" L x 1.0" T
Tape types: 9840

The StorageTek 9840 is a center-load, quick-access tape.  The cartridge contains two spools, so the tape always remains inside the cartridge, which gives it fast load and unload times.   As of 2014 there are four drives in the series: 9840A, 9840B, 9840C, 9840D. The drives all use the same 9840 media. Capacity is shown below.
The tape cartridge design is unique to the StorageTek T9840 drive and cannot be read in the StorageTek T9940, or in other drives such as 3480 or 3590.
