Claims

1. The recording medium containing

a first type data stream, a second type data stream associated with a first type data stream, and access control information for each of these data streams stored on the recording medium,

wherein the access control information includes type information indicating a type of associated data stream.

2. The recording medium according to claim 1, in which the access control information includes a file name of the associated data stream as position information of the associated data stream.

3. The recording medium according to claim 1, in which the access control information includes position information of the associated data stream and in which, if the type information indicates that the associated data stream is of the first type, the position information is a value corresponding to the distance between a particular position in a file storing control information for all data streams of the first type recorded on the recording medium and the starting position of the associated data stream.

4. The recording medium according to claim 1, in which the access control information includes position information of the associated data stream and in which, if the type information indicates that the associated data stream is of the second type, the position information is a value corresponding to the absolute address of the starting position of the associated data stream.

5. The recording medium according to claim 1, further comprising attribute information for a second type of data stream recorded thereon.

6. A method of recording data on a recording medium, comprising the steps of:

(a) recording a data stream of a first type and a data stream of a second type associated with a data stream of a first type on a recording medium; and

(b) creating access control information for each of these data streams and writing the generated access control information to the recording medium,

7. The method according to claim 6, in which at step (b) write access control information, including the file name of the associated data stream as information about the position of the associated data stream.

8. The method according to claim 6, in which, in step (b), access control information is recorded, including position information of the associated data stream, so that the position information is a value corresponding to the distance between a specific position in a file storing control information for all data streams of the first type recorded on the recording medium, and the initial position of the associated data stream, if the type information indicates that the associated data stream is of the first type.

9. The method according to claim 6, in which at step (b) write access control information, including information about the position of the associated data stream, so that the position information is a value corresponding to the absolute address of the initial position of the associated data stream, if the information about type indicates that the associated data stream is of the second type.

10. The method according to claim 6, further comprising storing on the recording medium attribute information for a data stream of the second type.

11. A method for reproducing a recorded data stream from a recording medium, comprising the steps of:

(a) reading access control information for the data stream from the recording medium;

(b) determining whether the data stream is a first type data stream or a second type data stream associated with a first type data stream based on type information included in the read access control information; and

(c) receive a data stream and information about the data stream in accordance with a specific type.

12. The method of claim 11, wherein in step (c), the data stream is read from the recording medium by setting the data stream based on the file name of the associated data stream included in the read access control information.

13. The method according to claim 11, in which if the particular type is the first type, then in step (c) the data stream is read from a position separated by a distance corresponding to the value of position information indicating the position of the associated data stream from a specific position in a file storing control information for all data streams of the first type recorded on the recording medium, the position information being included in the read access control information.

14. The method according to claim 11, in which, if the particular type is the second type, then in step (c) the data stream is read from a position corresponding to the position information value indicating the position of the associated data stream, and the position information is included in read access control information.

15. The method according to claim 11, in which, if the particular type is the first type, then in step (c) the attribute information for the data stream is read from the attribute information table located in the control information for all data streams of the first type recorded on a recording medium, and the read attribute information is used as information to control decoding of the data stream.

16. The method according to claim 11, in which, if the specific type is the second type, in step (c) the attribute information for the data stream is read, which is included in the access control information or stored in a separate file, and the read attribute information is used in quality of information for decoding data stream control.

17. A device for reproducing a data stream from a recording medium containing

an actuator for driving optical reproduction means for reproducing data recorded on a recording medium;

a decoder for decoding a data stream reproduced by the optical reproduction means; and

a controller for controlling the drive for reading access control information for the data stream, to determine, based on the type information included in the access control information, whether the data stream is a first type data stream or a second type data stream associated with a first type data stream, and to control the drive to obtain a data stream and information about the data stream in accordance with a specific type.

18. The device according to 17, in which the controller controls the drive to read the data stream from the recording medium based on the file name of the associated data stream, and this file name is included in the access control information.

19. The device according to 17, in which, if the particular type is the first type, the controller controls the drive to read the data stream from a position separated by a distance corresponding to the value of position information indicating the position of the associated data stream from a specific position in the file storing access control information for all data streams of the first type recorded on the recording medium, the position information being included in the access control information.

20. The device according to 17, in which, if the specific type is the second type, the controller controls the drive to read the data stream from a position corresponding to the value of the position information indicating the position of the associated data stream, and the position information is included in the information access control.
