Abstract
A recording/reproducing method includes: reading a first uncompressed data from a first recording medium; reading the first uncompressed data from a buffer memory at a speed higher than a normal reproduction speed and compressing the read first uncompressed data to generate a compressed data; and recording the generated compressed data in a second recording medium; determining whether a predefined unit volume of compressed data is recorded in the second recording medium; and when it is determined that the predefined unit volume of compressed data is not yet recorded in the second recording medium, 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 when it is determined that the predefined unit volume of compressed data is already recorded in the second recording medium.
