Abstract
A recording-and-reproducing apparatus for reproducibly controlling data recorded on a recording medium includes: a device configured to acquire control information required for reproducing the data when the data is recorded; a device configured to control operations during the period from the start to the end of recording data on the recording medium. The apparatus further includes a device configured to determine whether a recorded file of the data exceeds a predetermined limit of a storage capacity of a file system in the recoding medium and sequentially generate a subsequent recorded file upon exceeding the limit. Moreover, the apparatus includes a device configured to generate a single recording-and-reproducing unit during the period on the recording medium indicated by the control device based on a plurality of recorded files upon exceeding the limit; and a device configured to update the control information by recording the single recording-and-reproducing unit on the control information.
