ABSTRACT:
In a tape cartridge (20), a snap pin fastener (100) is provided for securing the cover (88) and base plate (90) while permitting therebetween differential expansion in a longitudinal direction (108) of the base plate. One dimension (112) of the snap pin is chosen small enough to flex under a force induced by differential thermal expansion of the cover and base plate. Thus the base plate remains flat, insuring registration between the tape and a transducer head. The second dimension (114) is chosen great enough to provide, with the first dimension, a cross section (115) sufficient to resist operational forces placed on the cover and base.
