ABSTRACT:
A media detection system includes a light source mounted within a cartridge receiving chamber defined by a cartridge engaging assembly. A cartridge referencing member has an arm portion mounted to the cartridge engaging assembly and a head portion located within the cartridge receiving chamber at a position adjacent the light source. The cartridge referencing member is deflected by a data cartridge within the cartridge receiving chamber so that when no data cartridge is located within the cartridge receiving member, the cartridge referencing member is not deflected and the cartridge referencing member blocks light from the light source. When a data cartridge is located within the cartridge receiving member, the cartridge referencing member blocks less light from the light source. A detector assembly mounted within the cartridge receiving chamber detects whether light from the light source is blocked or not blocked.
