Information recording medium, information recording apparatus and method, and computer program

Abstract

An information recording medium (100) is provided with: a record information area (106) to record therein record information; an edge portion area (104, 108, 109) which is located in at least one edge portion of the record information area; and a flag area (121) to record therein a first pre-record flag for indicating whether or not predetermined pre-information is pre-recorded in at least one portion of the edge portion area.

Description

TECHNICAL FIELD [0001] The present invention relates to an information recording medium, such as a DVD, an information recording apparatus, such as a DVD recorder, an information recording method, and a computer program which makes a computer as the information recording apparatus. BACKGROUND ART [0002] As described in Patent Documents 1 and 2, in an information recording medium, for example, such as a Compact Disc (CD) and a DVD, embossed pits or pre-marks are formed in advance in a necessity minimal area in a lead-in area, in order to prevent illegal copying and falsification of management information or control information. [0003] Alternatively, as described in Patent Document 3, as for the recording operation of a multilayer optical disc, there is a technology of efficiently forming a buffer area for layer jump. [0004] Moreover, as described in Patent Document 4, as for the recording operation of a single layer or multilayer optical disc, there is also a technology of controllin...

Benefits of technology

[0067] As explained above, according to the information recording medium of the present invention, it is provided with the record information area, the edge portion area, and the flag area. Therefore, it is possible to efficiently record the information onto the information recording medium, and it is also possible to reduce a recording time.

[0068] According to the information recording apparatus of the present invention, it is provided with the pre-recording device, the flag recording device, and the information recording device. According to the information recording method of the present invention, it is provided with the pre-recording process, the flag recording process, and the information recording process. Therefore, it is possible to efficiently record the information onto the information recording medium, and it is also possible to reduce a recording time.

Problems solved by technology

Thus, there is such a technical problem that even if the length of the lead-out area is reduced or the high-speed recording is performed in the lead-out area, it is inevitable that it takes time to perform the recording in the lead-out area.
