    摘要: Information recording is conducted in the form of the simple format. When the simple format is indicated, the recording control data is not recorded in a lead-in area LIA, and after the information to be recorded is recorded in a data recording area DRA, the recording control data is recorded in a recording manager area RMA and a lead-out area LOA, in the data recording area DRA, recording manager area RMA, lead-in area LIA, and lead-out area LOA, which are predetermined according to the standard format. Further, when the finalizing processing is indicated, by recording again the recording control data according to the standard format to the information recording medium in which the information recording is conducted according to the simple format, the information recording medium which can be applied to the common information recording and reproducing apparatus, is easily realized.
