  • Patent number: 6055500
    Abstract: A voice recording/reproducing apparatus including a first recording device for recording voice data converted into a digital signal in a solid-state memory. A data read device reads out the voice data which is written in the solid-state memory by the first recording device. A D/A conversion device converts the voice data which is read out from the solid-state memory by the data read device into an analog voice signal. A second recording device records the analog voice signal output from the D/A conversion device on a tape-like recording medium. A reproduction device reproduces the analog voice signal which is recorded on the tape-like recording medium by the second recording device. An output switching device switches between the analog voice signal output by the D/A conversion device and the analog voice signal reproduced by the reproduction device, and outputs a selected one of the analog voice signals.
