    • A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which a plurality of fields of video signals are recorded for each track turn on a spiral track comprises a reproducing transducer having a reproducing element for scanning over tracks on the rotary recording medium to reproduce recorded signals, and shifting device responsive to a signal applied thereto for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium, and a circuit for producing shifting a signal in order to shift the reproducing element by one track pitch towards the outer side on the rotary recording medium every time the reproducing element reaches one predetermined position on the rotary recording medium, and capable of producing a shifting signal for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium according to the slow-motion ratio and the direction of the slow-motion reproduction when the reproducing element reaches another predetermined position on the rotary recording medium. The shifting signal is supplied to the shifting device. The tracks are reproduced a plurality of times with respect to each track turn, to perform a slow-motion reproduction.
    • 用于再生旋转记录介质的旋转记录介质再现装置,其中记录有用于每个轨道的多个视场信号在螺旋轨迹上的旋转记录介质,其特征在于,具有用于在所述旋转记录介质上的轨道上进行扫描的再现元件的再现元件, 记录信号和移位装置,其响应于施加到其上的信号,用于使再现元件朝向旋转记录介质上的外侧或内侧移动,以及用于产生移位信号的电路,以便将再现元件移位一个磁道间距 每当再现元件到达旋转记录介质上的一个预定位置时,在旋转记录介质上的外侧,并且能够产生用于使再现元件朝向旋转记录介质上的外侧或内侧移动的移位信号, 慢速运动比和慢动作方向 当再现元件到达旋转记录介质上的另一预定位置时的产生。 换档信号被提供给换档装置。 轨道相对于每个轨道转弯多次再现,以执行慢动作再现。
