Facsimile Tape

    If an extensive power network is not available for drive power at the scanner and recorder, three alternatives can be considered. A double helix at the recorder with scanner and recorder drive essentially at same speed. A start-stop method disclosed by:

     Hell (U.S. Patent 2,113,429, R.Hell) may also be employed.

    The ideal, of course, is complete synchronous drive.

    A companion facsimile symposium paper, prepared by:

    Shore and Whitaker (RCA Institutes Technical Press, “Radio Facsimile”, pp.270-283, by Henry Shore and J.N. Whitaker) reports on a development program directed to provide a synchronous drive system satisfactory for commercial service.
