An information data recording and reproducing apparatus and an information data processing system (information data recording and reproducing apparatus and information data processing system)

摘要

The data compression means compresses the information data input from the input means. The input buffer means temporarily stores the compressed data obtained by the data compression means. The recording and reproducing means records the compressed data read from the input buffer means on a recording medium and reproduces the extruded data recorded on the recording medium. The output buffer means temporarily stores the compressed data reproduced by the recording and reproducing means. The data stretching means stretches the compressed data read from the output buffer means. The output means outputs the data stretched by the stretching means. Therefore, when one piece of information data is made to be an information data file, a portion recorded in the same information data file, for example, several tens of minutes before reproduction can be reproduced without requiring interruption of recording of the entire information data file .
