Why Magstar MP 3570 C02/C12/C22 are called as Tape drives?

Hi

Why IBM categorized Magstar MP 3570 C02/C12/C22 as Tape Drive.

Why not as Library? It has 2 drives, 20 slots, barcode reader, etc..  I
haven't worked on it, just came across reading Library and Tape drive
Specs.

Thanks

Regards

Raghu.
