ABSTRACT:
A data recording/reproducing apparatus in which speech data and video data can be recorded or reproduced separately from each other, the number of channels of the speech data can be changed or in which plural speech data with different number of channels can co-exist. A random-accessible vide data storage device and a random-accessible speech data storage device are provided separately for separately recording or reproducing video data and speech data. A video data file and a speech data file, obtained on dividing the video data and the speech data into respective plural records and recording the resulting records by the above data storage devices, are managed by a CPU using a file entry stored in a RAM or a file management information storage unit, a video data record entry and a speech data record entry.
