The foregoing record disk is conveniently molded in correspondence with an original recording disk produced by directing a laser light beam which has a Gaussian energy distribution thereacross against a layer of positive type photo-resist material on the original recording disk while the latter and the light beam are moved relative to each other for scanning a spiral track of constant pitch on the original recording disk and while the intensity of the laser light beam is modulated by the information signals to be recorded, and then developing the layer of photo-resist material.

摘要： In optically producing a reproducible recording of video or other signals, the intensity of at least one laser light beam is modulated by the signals to be recorded while such light beam scans a substantially flat surface on a photo-sensitive recording medium which is photo-reacted to a degree varying substantially linearly in correspondence with the intensity of the light impinging thereon over a predetermined range of light intensities, and the intensity of the light beam and the degree of modulation thereof by the signals are selected to maintain the maximum and minimum intensities of the modulated light beam within such predetermined range so as to form simultaneously on the record medium a tracking path portion and a recorded signal portion which is unified with the latter. The photo-sensitive record medium is desirably constituted by a positive photo-resist so that, upon development thereof, the tracking path portion is obtained in the form of a groove having the recorded signal portion defined by irregularities at the bottom of such groove. The positive photo-resist or other photo-sensitive material may be conveniently applied as a layer on a base plate or disc which is rotated while the light beam and disc are moved relative to each other in a radial direction of the disc so that the groove or other tracking path portion forms a spiral.

摘要： An indicator display tube in which indicator electrode units, each consisting of anode and cathode segments, lie in the same plane and in which all of the cathode segments are simultaneously energized and the anode electrodes are energized on a time sequential basis in such a manner that only the indicator electrode unit having its anode electrodes energized will glow at a particular time. The cathode segments of each indicator unit are connected in parallel which substantially reduces the number of leads to the display tube over conventional indicators which require a separate lead for energizing each of the cathode segments. The indicator display tube has means for preventing accidental discharge of adjacent indicator electrode units which would produce erroneous message displays.
