TLDR
In this article, the rotary heads are used to record or reproduce video signals in tracks extending obliquely across a magnetic tape as the latter is transported or driven about a guide drum and a fixed head for recording or reproducing control signals.
Abstract
In a video signal recording and reproducing apparatus having one or more rotary heads for recording or reproducing video signals in tracks extending obliquely across a magnetic tape as the latter is transported or driven about a guide drum and a fixed head for recording or reproducing control signals at spaced locations along the tape corresponding to the tracks, the tape is automatically brought to rest with its last recorded or reproduced track at a predetermined position relative to the path of the rotary heads whenever driving of the tape is halted, as for the still reproduction of a television picture or for the editing of the video signals recorded on the tape.

Apparatus for recording and reproducing video signals at selectable different tape traveling speeds from a plurality of pairs of video heads

TL;DR: A video signal recording and reproducing apparatus comprises at least two pairs of video heads respectively mounted at different positions on diametrically opposite sides of a rotary member rotating at a predetermined speed and recording and reproduction video signals on and from parallel tracks disposed obliquely relative to the tape longitudinal direction of a tape as mentioned in this paper.

Slow motion tape driving system in a recording and/or reproducing apparatus

Ota Yoshihiko
TL;DR: In this article, a tape driving system is adapted to be used in a recording and/or reproducing apparatus having at least one rotating head for tracing tracks on which a video signal has been recorded.
Patent

Video tape editor

TL;DR: In this article, the insertion and assembly of video signals are carried out using a VTR having helically scanning rotary record/playback heads, and the tape is advanced to a noiseless-still-picture position, based on a counted number of oscillations associated with rotation of the tape capstan, at which an acceptably noise-free picture is obtained.
