A recording medium for storing defect management information to record real time
data, a defect managing method therefor, and a method of recording real time data.
The recording medium stores information representing use or non-use of linear replacement
defect management in which a defective area on the recording medium is replaced
with the spare area, in order to record real time data. While maintaining compatibility
between the defect managing method and a defect managing method based on a current
DVD-RAM standard, i.e., while allowing a report of the fact that there are blocks
which have not been linearly replaced, linear replacement is not performed when
real time data is recorded. Thus, real time data can be recorded and reproduced.
