A disc processor, such as a printer or a recorder, or a combination processor, has a robotic arm that will pick a compact disc to be processed from a storage stack and move it to a tray associated with the processor. The robotic arm includes a sensor to sense when a disc is in a position to be held in a picker on the arm. The sensor signal can be used for determining whether or not the stack of discs in the input bin is of the correct height; for determining whether or not more than one disc has been picked up by the handler; and also for determining the presence of a disc in the tray or held on the picker arm.

A label for a component is provided with a continuous color tone background at least in segments of the label that can be detected as to a configuration using selected colored light sources which reflect from the different color tones of the label. A sensor can be used for discriminating between the reflection patterns from the light sources. A continuous color tone on the label changing smoothly from one color to others is applied to make a uniform shading from one color at one end of the label to another color at a second end, with various colors between the two ends. As an added feature, a number of black appearing strips forming a bar code can be provided on the label, with some of the strips reflecting infrared light and others not reflecting infrared light, so an infrared detector can be utilized for determining the pattern of the bar code for further identification of the labeled component. The bar code pattern will not be identifiable with the naked eye.
