A cartridge case has the same general geometry and dimensions of a Magstar cartridge,
but with modified lateral sides with recessed surfaces and additional gripping
notches that permit the alternative use of the cartridge with either a Magstar
or an LTO type of automated picker. The width of the bottom rear portion of the
cartridge is reduced to conform to the width of a standard LTO cartridge and LTO
gripping notches are provided by increasing the depth of the locating notches of
the Magstar format to the size required for engagement by the fingers in the gripper
arms of an LTO automated picker. As a result of this modification, the cartridge
of the invention can be alternatively handled by either Magstar or LTO type of
automated pickers.
