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.
An information recording medium of which the number of times of data rewrite to an identical area is limited, the information recording medium comprising:
An information recording method for recording information on an information recording medium of which the number of times of data rewrite to an identical area is limited, the information recording medium including an information recording area to which sequential loop recording is to be performed, and a pointer information recording area, the information recording method comprising the steps of:
An information recording apparatus for recording information on an information recording medium of which the number of times of data rewrite to an identical area is limited, the information recording medium including an information recording area to which sequential loop recording is to be performed, and a pointer information recording area, the information recording apparatus comprising:
