Claim:
A recording device comprising: a recording medium control unit for controlling recording and reproduction of data on a recording medium including a data area in which data rows can be recorded as files and a specific area in which management information for the files can be recorded, and a recording control unit for time-divisionally recording, through the recording medium control unit, a first data row as a first file having a variable size and a second data row different from the first data row as a second file having a variable size, wherein the recording control unit reserves an area in the data area, adds an end of file entry of the first file that references an end location of the first file in the reserved area as part of the management information, and then records the first data row in the reserved area in sequence as a first file from which the first data row can be referenced, and wherein when switching from the first data row to the second data row for recording, the recording control unit rewrites the management information corresponding to the end of file entry of the first file to reference a new end location of the first file recorded in the reserved area immediately before the switching such that the first file ends at the new end location on the recording medium and records the second data row from a location subsequent to the new end location on the recording medium referenced by the end of file entry of the first file in the reserved area.
