Abstract
A data compressing unit compresses information data inputted from an input unit. An input buffer unit temporarily stores the compressed data obtained by the data compressing unit. A recording/reproducing unit records the compressed data read out from the input buffer unit onto a recording medium, and reproduces the compressed data recorded on the recording medium. An output buffer unit temporarily stores the compressed data reproduced by the recording/reproducing unit. A data expanding unit expands the compressed data read out from the output buffer unit. An output unit outputs data expanded by the expanding unit. For this reason, when one set or cluster of information data is assumed to be information data file, it is possible to reproduce, without necessity of interruption of recording of the entirety of the information data file, the portion recorded earlier, e.g., by several minutes to several tens minutes within the same information data file.
