The first cartridge includes a first recess pattern () that receives the first protrusion pattern () thereby allowing full insertion of the first cartridge into the first cartridge drive. The second cartridge includes a second recess pattern () that receives the second protrusion pattern () thereby allowing full insertion of the second cartridge into the second cartridge drive. The second protrusion pattern () can impede full insertion of the first cartridge into the second cartridge drive. Further, the first protrusion pattern () can impede full insertion of the second cartridge into the first cartridge drive. The protrusion patterns () include protrusions () each having a protrusion length (A-D) which can vary between cartridge drives (). The cartridge () includes a cartridge housing () having a cartridge rear wall () and a plurality of cartridge side walls (). The recess patterns () can be positioned along one or more of the cartridge side walls () and/or the cartridge rear wall ().
