ABSTRACT:
In a data recording apparatus and its method, data is compressed in units of a stated data block, it is detected in units of the data block whether or not data extension has occurred in consequence of the compression processing. Then, the compressed data is recorded on a recording medium in the case where the data extension has not detected, and on the other hand, in the case where the data extension has detected, the original data is recorded on a recording medium with respect to a stated number of data blocks subsequent to the data block in which the data extension has occurred. Thereby, a data recording apparatus and its method can be realized with a simple construction, which can record non-compressed original data on the recording medium with respect to a string of data in which the data extension is apt to occur, and thus can alleviate bad influence of data extension which occur in consequence of the compression processing.
