。[Claims for Utility Model Registration] When an audio signal recorded on an information recording medium is reproduced at high speed, the high-speed reproduced audio signal is intermittently delayed so that the waveform becomes substantially the same as the audio signal waveform during normal reproduction. In an information recording and reproducing apparatus equipped with an audio fast-listening function that reproduces an audio signal at a faster speed than the recorded speed, the high-frequency components of the reproduced audio signal reproduced by the audio fast-listening function are removed. and a switching means for appropriately selecting and outputting the reproduced audio signal from which high-frequency components have been removed by the eliminating means and the reproduced audio signal reproduced by the audio fast listening function. An information recording/reproducing device characterized by:
