    摘要: In a video tape recorder of the helical scan type, two auxiliary magnetic heads having different azimuth angles are provided in the vicinity of two main magnetic heads. The main and auxiliary magnetic heads have their tracks aligned so as to compensate for the reduced period of the reproduction signal of the main magnetic heads during high speed reproduction by using the reproduction signals of the auxiliary magnetic heads. Thus, blur free high speed reproduction pictures may be realized, and, at the same time, a dancing picture correction during still reproduction may be facilitated.

    摘要: A recording time mode detector for automatically detecting the recording time mode of reproducing video tape. This detector is constructed of a counter which counts the number of rotations of the capstan which drives the reproducing video tape and is reset by a reproduced control signal. The recording time mode is detected by the count stored in the counter.

    摘要: A positionable element driving circuit for driving a positionable element compensates the supplied voltage-position characteristics of a bimorph type piezoelectric element which is used in a track following type video tape recorder/reproducer and which displaces the position of a video head. The supplied voltage to the bimorph type piezoelectric element is generated by an operational circuit which detects the track position of the video head. The circuit of the present invention compensates for the non-linearity and maintains the track following when the video tape recorder/reproducer is switched from one mode to another, e.g. from a still motion mode to a quick motion mode.
