Abstract

The invention discloses an information recording medium and information recording method. According to one embodiment, an information recording medium which is configured to record information includes a first area (2105, 2106) which stores first information indicating the range of a currently formatted area, and a second area (2107, 2108) which stores second information indicating the range of a previously formatted area.

Description

technical field [0001] An embodiment of the present invention relates to a recordable information recording medium and an information recording method for recording information on the information recording medium. Background technique [0002] As a recording medium that can record a large amount of information such as video signals and the like, DVDs (Digital Versatile Discs) have become popular. With the popularity of rewritable recording media such as DVD-RW having high compatibility with DVD-ROM as read-only media, players are used at home to record broadcast video data on DVD, edit the video data, and view the video data become possible. A rewritable recording medium needs to hold management information to manage the recording state of user data, and secure a recordable management area for recording the management information on the inner or outer circumference side of the data area. This structure is disclosed in references such as Japanese Patent Application No. 2000...
