More Book Details

Description of the Book:

The process of recording information by deforming the surface of a thin plastic film in accordance with the information content of an electron beam is described including some of the military applications. The advantages of this relatively new process, called Thermoplastic Recording (TPR), over the magnetic recording process and the recording of information using a Flying Spot Scanner (FSS)-cathode ray tube-photographic film system are described. The packing density, capacity, and bandwidth of TPR and the FSS-film system are compared indicating analytically the advantages of the new recording technique. A formula for computing the bandwidth to a TPR system in terms of the system parameters is derived. The many problem areas in the TPR process are pin-pointed by comparing the fundamental parameters of the FSS-film system and those of the TPR process. Particular emphasis is placed on beam and medium characteristics. An appendix detailing experimental work in the medium characteristics of thermoplastic recordings and the parameters affecting these characteristics is presented
