摘要： An apparatus for reproducing from a recording medium a frequency-modulated audio signal which has its carrier level in a specific period determined according to the kind of information and for producing the audio signal after processing the reproduced audio signal is arranged to control the signal processing action according to the output of a detecting circuit which detects the level of a difference between the carrier level of the frequency-modulated audio signal obtained in the specific period and the carrier level obtained in a period other than the specific period or detects changes taking place in the carrier level. This arrangement enables the apparatus to process the audio signal appositely to the kind of the frequency-modulated signal thereof without recourse to any additional reproducing circuit solely for this purpose. Further, the apparatus is arranged to prevent any faulty signal processing action by nullifying as necessary the output of the detecting circuit.

摘要： An apparatus is arranged to record a video signal in first areas respectively provided in a multiplicity of tracks on a recording medium and also a digital still-image signal in second areas which are respectively separated from the first areas. In the apparatus, while the digital still-image signal is being recorded in the second areas, the video signal is always recorded in the first areas, whereby it is possible to prevent occurrence of an uncomfortable phenomenon, such as formation of a scene devoid of a substantial image, during reproduction from the first areas. In addition, an analog still-image signal, representative of an image identical to an image represented by the digital still-image signal recorded in the second areas, is repeatedly recorded in the first areas during a predetermined time duration, whereby it is possible to facilitate search of a still-image signal recorded in the second areas. In addition, the digital still-image signal is recorded in the second areas at intervals of a predetermined period during recording of an analog moving-image signal in the first areas, whereby it is possible to record as many still images as possible.
摘要翻译：一种装置被配置为在分别设置在记录介质上的多个磁道中的第一区域中记录视频信号，并且在第二区域中记录分别与第一区域分离的数字静止图像信号。在该装置中，当数字静态图像信号被记录在第二区域中时，视频信号总是记录在第一区域中，由此可以防止出现不舒服的现象，例如形成没有在第一个地区的复制过程中形成了实质的形象。此外，表示与由第二区域记录的数字静止图像信号表示的图像相同的图像的模拟静止图像信号在预定的持续时间内被重复地记录在第一区域中，由此可以便于搜索记录在第二区域的静止图像信号。此外，在第一区域中记录模拟运动图像信号期间，以预定周期的间隔将数字静止图像信号记录在第二区域中，从而可以记录尽可能多的静止图像。
