摘要： An information processing apparatus includes an application execution unit configured to generate data to be recorded onto a medium that records data or reproduce data from the medium, a file system unit configured to manage data recorded on the medium using a file system, and a file conversion unit configured to perform conversion between a first file format processable by the application execution unit and a second file format defined by the file system. The file conversion unit converts a file of the first file format generated by the application execution unit into a file of the second file format having an allowable size defined by the file system and supplies the converted file to the file system unit in the form of a file to be recorded.
