Abstract: A recording/reproducing apparatus includes recording medium transporter. A counter counts a number of pulses corresponding to a distance moved by the recording medium in a first fixed period that includes the instant at which the recording medium starts to be fed and a second fixed period that includes the instant at which the recording medium stopping operation is actuated. The count result is utilized by a timing control to control either the timing with which the recording medium starts to be transported or the timing with which the recording medium is stopped. The recording medium is thereby set at a desired position with respect to a recording/reproducing device when it is being fed or is at rest.

Abstract: 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.

Abstract: 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.

Abstract: In the disclosed automatic tracking control device, a moving element in a VTR laterally moves a pick-up head relative to a recording track on a recording medium. A first control circuit produces a control signal for controlling the moving element to cause the head to trace recording tracks on the recording medium, and a sampling circuit samples the control signal produced by the first control circuit at times approximately corresponding to the mid-point of the movement of the lateral head. A second control controls a drive for driving the recording medium on the basis of the signal sampled by the sampling circuit.
