Abstract:
1. A recording/reproducing method, comprising: a first step for reading a first uncompressed data from a first recording medium; a second step for storing the first uncompressed data in a buffer memory; a third step for reading the first uncompressed data from the buffer memory at a speed higher than a normal reproduction speed of the first uncompressed data, the third step further compressing the read first uncompressed data to generate a compressed data and recording the generated compressed data in a second recording medium; a fourth step for determining whether a predefined unit volume of the compressed data is recorded in the second recording medium, and a fifth step for continuing the first step, the second step, and the third step when the fourth step determines that the predefined unit volume of the compressed data is not yet recorded in the second recording medium, the fifth step further generating a second uncompressed data by reading the compressed data from the second recording medium at a speed higher than the normal reproduction speed and decompressing the read compressed data in place of the first step, the second step, and the third step when the fourth step determines that the predefined unit volume of the compressed data is already recorded in the second recording medium, the fifth step then storing the generated second uncompressed data in the buffer memory.
