摘要： The present invention provides a recording/reproduction device that can perform post-record editing on a disk on which post-record editing has been determined to be impossible by conventional methods, and that can reproduce data that thus has been subjected to post-record editing, by devising a method for access in one cycle of repetitive processes of post-record editing. The recording/reproduction device is provided with a pick-up for recording or reproducing information and a control portion for controlling an operation of the pick-up, in which when reproduction is performed from an information recording medium on which in a separate area from a main sequence in which data blocks including original audio data and video data are recorded in succession, an additional sequence in which data blocks including post-record audio data are recorded in succession is formed, the control portion controls an operation of the pick-up in such a manner that the pick-up accesses the main sequence and the additional sequence alternately, and reproduces a plurality of data blocks in succession in each access.

摘要： To improve the convenience of a record medium and allow a reproduction process to be more easily performed than before. When a reproduction process 123 that reproduces material data recorded on a disc 32 is executed, a disc information file management section 63 references a reproduction history of a disc information file held in a disc information file hold section 52 and starts reproducing material data from a position according to the reproduction history. When the reproduction process is completed, the disc information file management section 63 updates the reproduction history of the disc information file held in the disc information file hold section 52. A disc information file record control section 82 records the updated disc information file on the disc 32.

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.
