FILE OPERATION METHOD EMPLOYING REAL TIME RECORDING/ REPRODUCING INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a recording medium that stores real time recording/ reproducing information, a real time recording and reproducing method and device, and a file operation method using this information. SOLUTION: A real time recording/reproducing attribute is given to a file by storing real time recording/reproducing information to a file control information area, each real time file or a separate file to warrant real time recording/ reproduction. Thus, a file recorded in real time can continuously be reproduced without interruption. Furthermore, the file provided with the real time recording/ reproducing attribute can be generated and the data area can be extended, recorded and reproduced.
