摘要： In a magnetic recording and reproducing system of the type wherein a plurality of rotating magnetic heads record the video signal on a magnetic tape as tracks which are inclined at an angle relative to the direction of travel of the magnetic tape, the audio signal is time compressed and recorded by the rotating magnetic heads on tracks contiguous with either or both ends of said video signal recording tracks, whereby even at a considerably low tape transport speed the audio signal may be recorded in a stable manner.

摘要： A two speed or multi-speed video tape recorder of the conventional helical scan type in which the audio signal is capable of being recorded as a time compressed signal at one end of each helical video scan, or alternatively, in conventional longitudinal fashion by means of a stationary magnetic head engaging one edge of the tape.At low tape transport speeds, improved bandwidth (and therefore sound fidelity) is obtained by use of the time compression technique; while at higher transport speeds, there are advantages in utilizing the stationary audio head.Circuitry is provided to automatically utilize the time compression technique at lower tape transport speeds and the stationary head longitudinal recording technique at higher tape transport speeds. A pilot or cue signal is recorded on the tape, to automatically control the reproduction circuitry so that both types of recording methods can be interchanged on the same magnetic tape, with the reproducing circuitry switching accordingly between the two modes, as required.

摘要： A method for positioning a composite head comprising a control head and an audio head in a rotary head type magnetic video recording and reproducing apparatus at a precise spacing relative to a mounting position of the rotary head is disclosed. A video signal is recorded intermittently for each group of a predetermined number of video tracks on a reference tape and an audio signal is also recorded intermittently in association with the intermittently recorded video signal. The composite head is adjusted and positioned such that the intermittent relationship existing between a reproduced video signal and a reproduced audio signal is the same as the intermittent relationship existing between the video signal and audio signal during recording.

摘要： In a video tape recorder of the helical scan type having a pair of heads mounted on diametrically opposite positions of a rotary cylinder, a pilot signal is recorded through the heads on the same track with video signal during recording and edit modes. During "insert" edit modes, the video heads are alternately switched between playback and recording modes in synchronism with each half revolution of the cylinder. A tape is wound over an arcuate extent greater than a semicircle of the circumference on the cylinder so that the video heads are simultaneously in contact with the tape at different positions to record a video signal over a major portion of the track and record a pilot signal over the full length of the track. One of the heads is in a recording mode and tracing the major portion of a given track, while the other head is in a playback mode tracing a minor portion of a subsequent track where the prerecorded pilot signal is present. A tracking signal is derived from the prerecorded pilot signal.
摘要翻译：在具有安装在旋转圆筒的径向相对位置的一对头部的螺旋扫描型录像机中，在记录和编辑模式期间，通过头部在同一轨道上记录带有视频信号的导频信号。在“插入”编辑模式期间，视频头在圆筒的每一半转之间同步地在重放和记录模式之间交替切换。磁带缠绕在大于圆柱体圆周半圆的弧形范围内，使得视频磁头在不同位置同时与磁带接触，以在轨道的主要部分上记录视频信号，并记录导频信号在轨道的整个长度上。其中一个磁头处于记录模式并跟踪给定磁道的主要部分，而另一个磁头处于重放模式，跟踪存在预先记录的导频信号的后续磁道的次要部分。从预先记录的导频信号导出跟踪信号。
