ABSTRACT:
Overlapping, and consequent illegibility, of recorded line scan or transverse records are precluded by delaying or inhibiting the recording process until the record sheet is being driven at or near full speed with respect to a normally blanked cathode ray tube record marking means. A voltage is established by a record speed select switch which must be substantially equaled by a voltage produced by a record sheet speed transducer before a comparator will turn on. The comparator output signal then allows the cathode ray tube to be unblanked and recording to start.
