摘要： In order to perform simultaneous recording of a plurality of pieces of real time data, a large capacity of buffer memories were required. In addition, it was difficult to reproduce data which was recorded by a different apparatus. The present invention has an objective of providing an information recording medium, a simultaneous recording method, and an information recording and reproduction apparatus which guarantee simultaneous recording. The simultaneous recording is guaranteed by reproducing data in each of areas having at least a minimum size fulfilling the simultaneous recording condition which allows for the number of access operations which is twice the number of pieces of real time data to be recorded, and when the data amount in the buffer is empty, switching the current recording operation to another recording operation to continue recording.

摘要： When recording data on a medium where a certain data rate is required, an allocation manager in the player must allocate sections of the logical space in such a way that the recording medium is efficiently filled and that an adequate data rate can be guaranteed even in the presence of defective ECC blocks. The allocation rules for the allocation manager are complex. The rules can be simplified by placing a lower limit on the size of an extent and by increasing the size of the extent depending on the number of defect ECC blocks in the extent.

摘要： In order to perform simultaneous recording and reproduction, a large capacity of buffer memories were required. In addition, it was difficult to record data while reproducing data which was recorded by a different apparatus. The present invention has an objective of providing an information recording medium, a simultaneous recording and reproduction method, and an information recording and reproduction apparatus which guarantee simultaneous recording and reproduction. The simultaneous recording and reproduction is guaranteed by reproducing data recorded in an area having at least a minimum size fulfilling the simultaneous recording and reproduction condition which allows for four access operations, recording data in an area having at least the same size, and performing reproduction and recording alternately by switching reproduction to recording when the data amount in the reproduction buffer becomes full and switching recording to reproduction when the data amount in the recording buffer becomes empty.

摘要： An information recording medium comprises a data recording area. A lead-in area and a volume space are allocated in the data recording area in advance. The volume space is constructed so as to allow a logical zone for recording at least a volume-file structure and an over-run protection area for preventing an access to an unrecorded area to be alternately allocated in the volume space. The lead-in area and the over-run protection area each include a chain volume management information area for storing chain volume management information. The chain volume management information includes address information of a subsequent logical zone and address information of a subsequent chain volume management information area.

摘要： According to a recording method for a conventional rewritable disc, the latest data is recorded by rewriting data in an identical area. In the case of a disc of which the number of times of data rewrite is limited, this causes a problem that a defect block is easily generated. The present invention has an objective of providing an information recording medium, an information recording and reproduction method, and an information recording and reproduction system apparatus, by which data is recorded sequentially from an unallocated area after an entry sector number, and data recording is sequentially repeated from an inner portion to an outer portion.

摘要： An information recording medium for recording a real-time file containing real-time data in such a manner that the real-time data is continuously reproducible by a playback reference model, the real-time data including at least one of video data and audio data. The playback reference model includes: a pickup for reading the real-time data from the information recording medium; a buffer memory for temporarily storing the real-time data read by the pickup; and a decoder module for reading the real-time data from the buffer memory for processing. The information recording medium includes a volume space for at least recording in sectors a file containing data and file management information for managing the file. The real-time data is recorded in at least two real-time extents each of which is allocated in logically contiguous sectors within the volume space. An (i+1)th real-time extent among the at least two real-time extents is positioned at a position satisfying a real-time reproduction condition.

摘要： The present invention has as an object to accomplish reliable data reproduction in a data reproducing apparatus in which servo operation easily becomes unstable in an unrecorded disc area, and provides a data storage medium whereby the highest address of the reproducible data area is obtained by the optical disc drive, and reproduction is possible using only a normal READ command, without providing a physical area in the volume space. Address information (181) for an integrity information area (111) allocated in the first overrun extent in the volume space is recorded to a lead-in area (101) reproducible by an optical disc drive. As a result, when a disc is inserted to a data reproducing apparatus, address information for the first integrity information in the volume space is recorded to the lead-in area, or the highest address of the reproducible data area is obtained by the data reproducing apparatus following the integrity information, preventing the optical disc drive from accessing an unrecorded disc area.

摘要： Congested rewriting in the same area is to be evaded to suppress the tendency towards occurrence of defective areas. When a stream 1 has been recorded, the last written address, representing the last written position, is stored. When recording a stream 2 next, recording is started directly following the position indicated by the last written address for the stream 1. The last written address, corresponding to the last address of the recording position, is stored. If the stream 2 is erased for recording a stream 3, recording is started not at a position directly following the last written address of the stream 1, but from a position directly following the last written address of the stream 2. When the stream 3 has reached the end of a recording area, the next following data is recorded as from a position directly following the stream 1.
