    • Apparatus for recording and reproducing audio signals on flat rectangular recording media comprising a magnetic coating or the like on at least one side. A magnetic head on a swing arm moves across the magnetic media in mutually parallel lines guided by a heart-shaped cam, the recording medium being stationary during recording and reproducing so its visible surface can be examined without difficulty. The heart-shaped cam is of asymmetric configuration, and the magnetic head is pivotably mounted on one end of the swing arm which carries between its ends a cam follower peg which continually engages the heart-shaped cam while under spring loading. The other end of said swing arm is pivotably mounted on a sliding carriage plate which is moved stepwise perpendicularly to the chord of the curved path of movement of the magnetic head for each line. The stepwise perpendicular movement of the sliding carriage plate is produced by a mechanism which is controlled by the reversal of direction of the magnetic head.
    • 用于在平坦的矩形记录介质上记录和再现音频信号的装置,包括在至少一个侧面上的磁性涂层等。 摇臂上的磁头在由心形凸轮引导的相互平行的线中移动穿过磁性介质,记录介质在记录和再现期间是静止的,因此可以毫无困难地检查其可见表面。 心形凸轮具有不对称构型,并且磁头可枢转地安装在摆动臂的一端,该端部在其端部之间承载凸轮从动栓,该弹簧从动栓在弹簧加载期间与心形凸轮连续接合。 所述摆臂的另一端可枢转地安装在滑动滑架板上,该滑动滑板平行于每个线的磁头的弯曲运动路径的弦线逐步移动。 滑动滑架板的逐步垂直运动通过由磁头的方向反转来控制的机构产生。
