摘要： A magnetic recording and reproducing apparatus for reproducing information from a track recorded on a magnetic tape made to travel by being driven by a capstan. Even if a track has been recorded in a curved form, a magnetic head is displaced substantially perpendicularly to a rotational axis of a rotating drum in correspondence with the curve so as to trace the track. A signal read from the track by the magnetic head is subjected to envelope detection and is converted to a digital envelope signal. The capstan is driven and controlled such that the intensity of the digital envelope signal becomes substantially maximum. At the same time, a comparison is made between an ideal scanning pattern for the magnetic head stored in advance and the digital envelope signal, the ideal scanning pattern is corrected on the basis of the result of comparison, and the magnetic head is displaced in a substantially perpendicular direction to the rotational axis of the rotating drum so that the intensity of the envelope signal becomes substantially maximum. The magnetic head is affixed to a projecting portion of an annular spring with an air-core bobbin fitted in a central portion thereof and is displaced by magnetic interaction between an energizing coil wound around the bobbin and a permanent magnet disposed inside the air-core bobbin.

摘要： While prior art apparatus for magnetic recording and playback (VTRs) were unable to perform magnetic recording of an FM signal with an optimum recording current responding to change of the optimum recording current dependent on kinds of magnetic tapes used and wear of heads, the magnetic recording of an FM signal with the optimum recording current at all times has been made possible by having a recorded signal along a track of a magnetic tape read by a level servo head scanning the track following the signal recording and having the recording current controlled to be optimized by use of a recording current controlling device based on the playback signal output from the level servo head. As a result, improvement of the S/N ratio and automatic adjustment of the recording current can be achieved. Further, by means of a head drive unit, the position of the level servo head is finely adjusted so that the control for optimization of the recording current is performed accurately.

摘要： By reverse biasing the PN junction formed around a semiconductor element, the semiconductor element is isolated from other elements. The PN junction around the semiconductor element is a junction between a layer surrounding the semiconductor element and a layer disposed outside the layer. Jointly with the layer constituting the semiconductor, the layer surrounding the semiconductor element forms a parasitic diode. The potential of the layer on the semiconductor element to be connected to the layer surrounding the semiconductor element is detected, and based on this potential, the voltage to be applied to the parasitic diode is controlled so as to be constant. When the voltage to be applied to the parasitic diode is lower than a threshold, the parasitic diode will be in a cutoff state.

摘要： A video signal processing apparatus which is adapted to a VTR (video tape recorder) and various other video players for processing a video signal so as to reduce noise. A video signal passed through a demodulator and a deemphasis circuit is input to a noise canceller circuit so as to remove most of the noise component thereof. The video signal is then provided with narrow and deep peaks at the respective rising transient portion and the breaking transient portion with bipolarity by an outline emphasizing circuit. Thus, smooth signal processing of the group delay characteristic is enabled in a wide frequency band, thereby producing a video signal having excellent sharpness and not including a strain such as overshoot or ringing.
