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： 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.

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： 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.
