<p>A method of managing compressible data files on a recording medium, the method comprising the steps of (a) determining or evaluating the space requirement of a data file or part of a data file to be newly recorded onto said recording medium; (b) if the space requirement exceeds the available space, selecting at least one data file previously recorded on said recording medium; (c) reproducing said at least one selected data file into at least one data stream (Xik) and compressing the data of each data stream by at least one specified reduction factor (ai) for each data stream (Xik) to reduce an information amount therein, characterized by (d) selecting the reduction factors, such that the bitrate (Xnew) of the data stream to be re-recorded onto said recording medium fulfills the following relation: (i) (Formula) (e) re-recording the compressed data streams. (f) recording the data stream to be newly recorded onto said recording medium, while reproducing, compressing and re-recording said selected data stream.</p> |
