Abstract: A file reproducing apparatus for reproducing files recorded on a recording medium by using a FAT (File Allocation Table) file system, which includes a cluster table which associates offset positions indicating the distances from the head of the file set at the predetermined offset intervals with cluster numbers indicating locations of the files recorded on the recording medium in which the data at the corresponding offset positions are stored. During a reproduction operation in a reverse direction which proceeds from the end of the file toward the head, the location of the data to be read is determined with reference to the cluster table.

Abstract: In a digital signal recording and reproducing apparatus, digital input data is transmitted in a transmission packet format and is recorded in a recording packet format. In a recording stage, an auxiliary signal generator (3) generates an auxiliary signal for special reproduction in the transmission packet format, and the digital and auxiliary signals are converted into respective recording packets by means of recording signal converters (5, 6). Recording means (9, 10) performs a specific recording process on the recording packets and an identification signal for identifying between the recording packets of the digital signal and of the auxiliary signal. While in a reproducing stage, reproduction signal processing means (14, 15) performs a specific reproduction process on the reproduction signal to thereby reconstruct the recording packets and the identification signal.
