Abstract: In a magnetic field detecting system having a dual-gap, magnetic flux responsive head and a magnetic flux generating source magnetized in directions across the gaps of the head, the source and head are moved relative to each other in a direction at right angles to the direction of magnetization, and such magnetization has a pattern that varies along the source considered in the direction of relative movement so that the output of the head may provide a signal of any desired wavelength limited only by the magnetization pattern.

Abstract: A method for recording a color video signal in a plurality of parallel tracks extending obliquely on a magnetic tape includes the steps of sampling the video signal at a frequency which is at least three times the color sub-carrier frequency of the color video signal, converting the sampled video signal into digital form, and recording respective pluralities of the digitized samples which are arranged in a predetermined sequence sequentially in the plurality of parallel tracks, by either recording respective pluralities of contiguous digitized samples sequentially in the tracks, in which each plurality corresponds to at least one cycle of the color sub-carrier, or by alternately separating contiguous ones of the digitized samples into first and second blocks and recording respective pluralities of successive digitized samples of the first and second blocks sequentially in the tracks with the sampling frequency being equal to four times the color sub-carrier frequency, such that the chrominance component of the digital color video signal can be separated during reproduction so as to correct any error in the phase of the color sub-carrier, and such that with the first embodiment of the last-mentioned step, a digital filter having a chrominance characteristic C=(1-Z -2)/2 can be used, and with the method according to the second embodiment, a fourth order digital filter having a chrominance characteristic C=(-1=2Z-2-Z-4)/2 can be used to reproduce the chrominance component, where Z is a delay transfer characteristic of the respective filters.

Abstract: An apparatus for cancelling an undesired signal includes a programmable filter in which differential waveforms of a desired signal are superimposed on one another to form a composite signal similar to an undesired signal, a control circuit for detecting a level of the undesired signal to control the gain of a level adjusting circuit of the programmable filter so as to have a value proportional to the undesired signal, and a substrate for subtracting the composite signal from an input signal.

Abstract: SO 1341 A method for recording a color video signal in a plurality of parallel tracks extending obliquely on a magnetic tape includes the steps of sampling the color video signal at a frequency which is at least three times the color sub-carrier frequency of the color video signal, converting the sampled color video signal into digital form, and recording respective pluralities of the digitized samples which are arranged in a predetermined sequence sequentially in the plurality of parallel tracks, the last-mentioned step being performed in a first embodiment by recording respective pluralities of contiguous digitized samples sequentially in the tracks, in which each plurality corresponds to at least one cycle of the color sub-carrier or the last-mentioned step being performed in a second embodiment by alternately separating contiguous ones of the digitized samples into first and second blocks and recording respective pluralities of successive digitized samples of the first and second blocks sequentially in the tracks, the sampling frequency in the second embodiment being equal to four times the color sub-carrier frequency. With this method, the chrominance component of the digital color video signal can be separated during reproduction so as to correct any error in the phase of the color sub-carrier. With the method according to the first embodiment a digital filter having a chrominance characteristic C = (1-Z-2)/2 can be used, and with the method according to the second embodiment, a fourth order digital filter having a chrominance characteristic C = (-1+2Z-2-Z-4)/2 can be used, where Z is a delay transfer characteristic of the respective filters.

Abstract: A method of recording and reproducing a video signal with respect to a magnetic tape includes the steps of converting the video signal into digital form; distributing the digitized video signal to a plurality of channels; simultaneously recording the digitized video signal in eight parallel tracks extending obliquely on the tape without guard bands therebetween and with the digitized video signal in alternate ones of the tracks being recorded with a first azimuth angle and the digitized video signal in the remaining tracks being recorded with a second different azimuth angle; reproducing the digitized video signal from the eight parallel tracks; grouping the reproduced digitized video signal into two groups, one group including only those portions of the reproduced digitized video signal that were recorded with the first azimuth angle, and the other group including only those portions of the reproduced digitized video signal that were recorded with the second azimuth angle; and processing the reproduced digitized video signal separately for each group. Apparatus for performing the above method is also provided.
