Information recorder, information recording medium, and information recording method
First Claim
1. An information recording device comprising a controller that adjusts recording conditions including a bit rate of time series data when recording a content in an information recording medium, wherein the controller includes an index information group creating unit that creates a time sequence index information group in which index information items extracted from the time series data for locating particular points of the content are arranged in time sequence of the time series data, and a reverse time sequence index information group in which the index information items are arranged in reverse time sequence of the time series data;
- and an index information group recording unit that records the time sequence index information group and the reverse time sequence index information group created by the index information group creating unit into an area of the information recording medium different from an area where the time series data are recorded.

7. An information recording medium in which a content in the form of time series data is recorded, comprising:
-
a first area in which the time series data are recorded; and
a second area in which a time sequence index information group and a reverse time sequence index information group are recorded, the time sequence index information group containing index information items, which are extracted from the time series data for locating particular points of the content, arranged in time sequence of the time series data, the reverse time sequence index information group containing the index information items arranged in reverse time sequence of the time series data. - View Dependent Claims (8)

10. An information recording method that records a content in the form of time series data in an information recording medium and reproduces particular points of the content, comprising:
-
an index information group creating step of creating a time sequence index information group in which index information items extracted from the time series data for locating the particular points of the content are arranged in time sequence of the time series data, and a reverse time sequence index information group in which the index information items are arranged in reverse time sequence of the time series data; and
an index information group recording step of recording the time sequence index information group and the reverse time sequence index information group created in the index information group creating step into an area of the information recording medium different from an area where the time series data are recorded. - View Dependent Claims (11, 12, 13, 14)
