Abstract

An attempt is made to make it possible to efficiently perform the finalizing process and closing process in a short period of time and securely manage the last address of a border-out. When the border closing or finalizing process is performed after user data is recorded, a padding process is performed (SA5) for at least a discontinuous area in the data area and a border-out is lastly recorded (SA6) in a first step. Then, in a second step, latest recording management data (RMD) is recorded (SA2) in a recording management data duplication zone (RDZ) of a data lead-in area, latest recording management data (RMD) is recorded (SA3) in an unrecorded area of a present recording management zone (RMZ) and R physical format information (R-PFI) is recorded (SA4) in an R physical format information zone (R-PFIZ).

Description

technical field [0001] The present invention relates to an information recording and reproducing apparatus and an information recording method using an information storage medium (or an information recording medium). Background technique [0002] An optical disc called a digital versatile disc (DVD) is provided as an information storage medium. As current DVD standards, there are read-only DVD-ROM standard, write-once-read-many DVD-R standard, rewritable (approximately 1000 times) type DVD-RW standard, and rewritable (10000 times or more) type DVD-RAM standard. [0003] In the recordable DVD standard, intermediate information (recording (position) management information) at the time of recording interruption is recorded in the lead-in area. In this case, it is necessary to additionally record the intermediate information once whenever recording interruption occurs. Since the number of recording interruptions increases as the recording density becomes higher and the data a...
