Apparatus for providing security for data storage devices, the apparatus comprising: a data storage
library (10) having a deep storage compartment
cell (100, 740) configured to receive a plurality of tape cartridges (500), the deep storage compartment
cell (100, 740) comprising: a front side (726) of the deep storage compartment
cell (100, 740) configured to enable
insertion and removal of a locking tape
cartridge (732) of the plurality of tape cartridges (500) by a robotic mechanism; a deep side (728) of the deep storage compartment cell (100, 740) configured to have an opening for engaging a
locking mechanism (730) that prevents a biasing spring mechanism (734) of the deep storage compartment cell (100, 740) from automatically pushing a rearmost tape
cartridge of the plurality of tape cartridges (500) forward toward the front side (726) of the deep storage compartment cell (100, 740); and a front air gap on the front side (726) of the deep storage compartment cell (100, 740) that prevents the
robot mechanism from reaching a frontmost tape
cartridge of the plurality of tape cartridges (500) after the
robot mechanism has removed the locking tape cartridge (732) from the deep storage compartment cell (100, 740).
