Abstract: A video recording and scanning system includes a disc-type record, and a record player, the record having both video picture signal producing indicia and synchronizing pulse producing indicia recorded on its spiral track, the length of the trackcarrying signals for recording each picture being variable to permit greater compression of information on a given track with short spacings, or greater image resolution detail with long spacings, the number of the pulse indicia having a fixed ratio to the number of individual pictures recorded on the disc, the position of each pulse indicium being fixed relative to the position of the indicia for producing each picture, the record player including a scanning means, a comparison circuit and a disc speed varying means, the scanning means being mounted for relative movement along the track and producing both picture signals and pulse signals, the comparison circuit comparing the frequency of the pulse signals to a reference frequency to produce an adjustment signal, and the disc speed varying means being responsive to the adjustment signal to vary the speed at which the record track moves past the scanning head so that the variable length portions of track-carrying signals for producing one image move past the scanning means in the same period of time and produce a constant picture changing frequency which is independent of the length of the track carrying the signals for producing each picture.

Abstract: A reproducing system for recording or playback of the type in which a stationary plate is mounted beneath a rotating round flexible foil type record and the stationary plate is formed with an upwardly arched surface with an elongated crest which, when the record is at rest, underlies a diameter of the record. Transducer means which may be either means for placing recording indicia on the carrier, or means for forming playback signals from indicia previously recorded on the carrier are mounted along a line overlying said crest. The air pressure between the record and the arched surface is reduced by air currents generated during rotation of the record. This draws the flexible record into a stiffened curved position relative to the plate, and thus better positions the record relative to the transducer means.

Abstract: A contact reproduction process for magnetic tape recordings wherein information is first recorded on a tape, which forms the original, in the form of at least one strand of magnetizable material having cross-sectional variations provided therein. The original tape is then brought into contact with a blank tape and, subsequently, both tapes are exposed to a direct-current field and a high frequency field superimposed thereon. Since the original tape cannot be erased, it can be exposed to an optimum field intensity.

Abstract: Method and means for recording two separate signal channels, pertaining, for example, to the video and audio information of a television signal, in the walls of a recording carrier groove in the form of modulated carrier signals which are to be magnetically sensed for playback.
