Abstract: A wideband transducer system including longitudinally recorded video, transversely recorded or multiplexed audio, channel shifting during blanking intervals, high frequency bias synchronized to audio carrier frequency or otherwise selected to avoid beat notes, head with plural windings switched to reduce inductance during recording and connected for wideband playback into an amplifier input with comparable or higher impedance than that of the winding.
Abstract translation: 一种宽带换能器系统，包括纵向记录的视频，横向记录或多路复用的音频，消隐间隔期间的信道移位，与音频载波频率同步的高频偏置或以其他方式选择以避免拍音，具有多个绕组的磁头，以在记录期间减少电感并连接 宽带播放成具有与绕组相当或更高阻抗的放大器输入。
