Abstract
Abstract A recording apparatus for recording audio signals and video signals on a recording medium in a mixed form is disclosed. The recording apparatus has a device for reproducing video signals which correspond to audio signals to be recorded prior to the execution of recording of the audio signals. Therefore, an operator can perform sound recording while confirming a correspondence between an image and the sound, since the image associated with the sound is reproduced as a visual image.
