Ｍ磁気記録再生機のＣＵＥ再生回路。[Claims for Utility Model Registration] (1) An error detection circuit for detecting data errors in reproduced digital data from a magnetic tape, a fader circuit for fading out input data in a data error section, and a fader circuit for fading out input data in a data error section; PCM magnetic recording, which supplies the memory to the fader circuit and has a delay time corresponding to the fade-out time of the data error section during variable speed playback, and a memory delay circuit that has a delay time corresponding to the PCM next time during steady speed playback. CUE playback circuit of playback machine. (2) The output of the error detection circuit is input to the fader circuit without going through the memory delay circuit during variable speed playback, while being delayed by the memory delay circuit and input to the fader circuit during steady playback. Scope of claim for utility model registration No. 1
The CUE reproducing circuit of the PCM magnetic recording/reproducing machine described in 2. (3) The PC according to claim 1, wherein the fader circuit performs its fade-out operation when the number of errors detected by the error detection circuit is a predetermined number or more consecutively.
CUE playback circuit of M magnetic recording/playback machine.
