摘要： PROBLEM TO BE SOLVED: To speed up and facilitate formation and confirmation of a middle area in a recording medium of a rewritable opposite track path having a plurality of recording layers. SOLUTION: Intermediate area management information (middle status) which indicates whether a intermediate area for guarding (middle area) whose one end is an inter-layer shifting position (inter-layer loopback address) which is fixed according to user data recording is already formed or not is made to be recorded in a predetermined management information area (for example, lead in) of a disk. Thereby, the recording and reproducing apparatus can decide whether the formation of the middle area is necessary or not from the value of the intermediate area management information.

摘要： PROBLEM TO BE SOLVED: To appropriately perform additional write of data based on address information of a disk medium.
SOLUTION: A data position counter 180 performs a count operation synchronizing with the reproducing operation of data already written in an optical disk 40. An LPP (Land PrePit) position counter 160 performs a count operation synchronizing with the reproducing operation of disk address recorded on the optical disk. An error detecting circuit 190 detects deviation between an address on a data format of data recorded on the optical disk 40 on the basis of these two count values CO1, CO2 and the address of the optical disk 40 at a position at which these data are recorded. A control unit 30 sets, on the optical disk 40, an address where the additional write of data is started on the basis of a detection result of the error detecting circuit 190. A timing control circuit 140 determines timing with which the additional write is started conforming to an address where the additional write is started.

摘要： PROBLEM TO BE SOLVED: To make it possible to collect a plurality of the contents authored for DVD to record easily them on a large-capacity information record medium and to increase a data rate in reproducing the recorded contents.SOLUTION: The information recording device performs the processes of: creating source packets from a disk image file; collecting them to form arrangement units 320; collecting them to form ECC clusters; collecting sectors of the DVD to form a sector group, thereby storing it while bringing it into correspondence with a predetermined number of source packets; adding a control packet to this to form units of conversion; collecting them to bring them into correspondence with an integral number of the arrangement units 320; and storing a cluster-number, at which a leading sector of the sector group of the DVD is stored in the control packet. The source packets are brought into correspondence so that a leading portion of the file system area coincides with both a leading portion of the arrangement unit and a leading portion of the ECC cluster and the disk image file is recorded using units of the length so that the length causes a boundary of the units of conversion to coincide with a boundary of the ECC clusters.
摘要翻译：要解决的问题：为了能够收集为DVD制作的多个内容，容易地将其记录在大容量信息记录介质上，并且在再现记录内容时提高数据速率。解决方案：信息记录设备执行以下处理：从磁盘映像文件创建源数据包; 收集它们以形成布置单元320; 收集它们以形成ECC簇; 收集DVD的扇区以形成扇区组，从而在将其与预定数量的源分组对应的同时存储; 向其添加控制包以形成转换单元; 收集它们以使它们与整体数量的排列单元320相对应; 并存储在该控制分组中存储有DVD的扇区组的前导扇区的簇号。源数据包相互对应，使得文件系统区域的前导部分与排列单元的前导部分和ECC簇的前导部分和磁盘映像文件两者的长度一致，长度导致转换单位的边界与ECC簇的边界一致。版权所有（C）2012，JPO＆INPIT
