  • Patent number: 7088539
    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.

  • Patent number: 6941569
    Abstract: A cartridge access device in a cartridge storage system is designed to retrieve a cartridge from a storage device and to transfer the cartridge to a particular location within the system. Once the cartridge is no longer needed at the particular location, the cartridge access device retrieves the cartridge from the particular location and returns the data cartridge to the storage device. The data cartridge device preferably includes at least two engaging members that engage a respective surface of a frame assembly. Channels in the surfaces of the frame assembly guide the engaging members and, therefore, the cartridge access device as the cartridge access device moves. The engaging members are engaged with a respective conductive track member that extends through the channels in the frame assembly.
