Optical recording medium, method for recording on optical record medium, and apparatus for recording on optical record medium |
摘要 |
An optical recording medium of the present invention includes a substrate (202), a protection plate (205), and a plurality of information layers (203) sandwiched between the substrate and the protection plate. An information signal is recorded as a length of a mark and a length of a space between two marks. The mark is formed when the information layer is irradiated by light received through the substrate. The information layers have a management region (206) recording a leading edge recording condition and a trailing edge recording condition. The leading edge recording condition is used to change a recording start position for forming a leading edge of the mark. The trailing edge recording condition is used to change a recording end position for forming a trailing edge of the mark. Each of the leading and trailing edge recording condition is depending on which information layer is recorded.
