1. An information recording medium that is machine-readable in which data is recorded by using a data structure, the data structure including a file structure area and a data area, wherein:
the data includes first AV data having a first attribute and second AV data having a second attribute which is different from the first attribute;
the data area has continuous areas; and
at least one of the continuous areas includes a first extent in which at least a portion of the first AV data is recorded and a second extent in which at least a portion of the second AV data is recorded,
wherein a difference between first time information and second time information recorded in a leading sector and a last sector, respectively, of the extent and a data size of AV data recorded in the extent represent an average data rate which is required for a transfer of the AV data recorded in the extent,
such that areas in which the AV data is recorded are managed as extents in the file structure;
and the leading sector and the last sector are read out to determine if AV data can be continuously reproduced.
