Thermoplastic Recording
William E. Glenn · Journal of the SMPTE · 1960
A new method is described for recording electrical signals. Information is written at extremely high density by means of an electron beam on a film consisting of a low-melting thermoplastic material. This can be projected as a full color image, or can be converted to an electrical signal. The tape, which is processed by quick heating, can be readily erased and re-used. A video recorder using this recording technique is described.
