  • Information recording apparatus including information attaching and generating device which generates group control information
    Patent number: 7200090
    Abstract: When a detection device detects any kind of change regarding track recording after the start of the track recording, a grouping instruction is given to information attaching and generating device. Then, the information attaching and generating device attaches the same group name information to a group, in which a track where the recording has been started in an information recording medium to a track recorded at the point when the grouping instruction has been received are made to be the same group, and group control information is generated. Therefore, since the grouping is automatically performed by any kind of change regarding the track recording, a user can omit the operation that he/she performs the grouping by himself/herself, and thus the operation load of the user can be reduced.
