A recording medium for storing real time recording/reproduction information, a
real time recording and reproducing method and apparatus, and a file operating
method using the information. Real time recording/reproduction information for
ensuring real time recording/reproduction is stored in a file control information
area, in each real time file, or in a separate file, and real time recording/reproduction
attributes are assigned to the file. Thus, real time recorded files can be continuously
reproduced without interruption. Also, there are methods of creating a file to
which real time recording/reproduction attributes are assigned, extending a data
area, and recording and reproducing the file to which real time recording/reproduction
attributes are assigned.
