Abstract :
IN ONE SYSTEM of customer toll dialing,1 the call record is a punched tape as shown in Figure 1. A simple recorder containing punch and step magnets driven directly by dial impulses produces the tape record. Transcribing information from the tape by eye would be slow and cumbersome; hence an automatic “reader” is needed to translate the information to a more convenient form.
