摘要： A video signal processing apparatus is arranged to process a composite information signal which is formed by multiplexing first and second information signals having different frequency bands. When the composite information signal recorded on a recording medium is reproduced, the first information signal is extracted from the reproduced composite information signal and a first detection signal is obtained by subjecting the extracted first information signal to a detection process. The second information signal is also extracted from the reproduced composite information signal and a second detection signal is obtained by subjecting the extracted second information signal to a detection process. The first and second detection signals are compared with each other. A correction process is performed on the composite information signal reproduced from the recording medium according to the result of comparison. The reproduced composite information signal can be adequately corrected by virtue of the arrangement.

摘要： The present invention provides an improvement in the function of automatically rewinding a tape-shaped recording medium to an immediately previous recording start position or to an immediately previous stop position, and the accuracy of this rewinding is improved by using pulses according to the rotation of a capstan. A position to which the tape-shaped recording medium is to be rewound is accurately associated not with the immediately previous travel start position of the medium but with the immediately previous recording start position. Further, when the tape-shaped recording medium is to be stopped after the rewinding, the stop position is made to differ from the immediately previous stop position of the tape-shaped recording medium, thereby preventing damage to the medium. Further, meaningless rewinding is prevented by disabling the aforesaid function on the basis of the amount or elapsed time of tape travel from the immediately previous recording start position. Further, whether the function is enabled is displayed for the sake of convenience of a user. Further, during the aforesaid rewinding, a signal is reproduced so that the user can judge whether the rewinding has succeeded. Further, there is provided the function of cancelling the aforesaid function and causing the tape-shaped recording medium to travel to a position where it was located before this function was operated.

摘要： The disclosed information signal recording and/or reproducing apparatus records or reproduces an information signal by shifting two electric-to-mechanical conversion elements which respectively have heads mounted thereon. Each electric-to-mechanical conversion element has a residual displacement characteristic. The shift direction of one conversion element is arranged to be the same as that of the other immediately before switchover from a first mode to a second mode. In the first mode, the difference between voltages impressed on the two elements is relatively large, and, in the second mode, the difference between voltages impressed on the two elements is relatively small.
