Abstract

If a program list prescribing an order to reproduce video and audio data is recorded in a binary-data format, a low affinity with a text-format language such as the XML results. For this reason, the program list is recorded as a file with a text format in addition to a file having the conventional binary-data format

Claims

1. A recording medium used for recording information, comprising:

a first program list prescribing an order to reproduce data; and

a second program list prescribing the same order to reproduce data as said first program list in a file format different from said first program list.

2. A recording medium according to claim 1, wherein said first program list is a list written in a text format and said second program list is a list written in a non-text format.

3. A recording apparatus for recording data onto a recording medium, comprising:

an optical pickup for radiating a light ray to said recording medium; and

a control microcomputer for controlling said recording apparatus,

wherein said control microcomputer controls an operation to record a first program list prescribing an order to reproduce data and a second program list prescribing the same order to reproduce data as said first program list in a file format different from said first program list onto said recording medium by using said optical pickup.

4. A recording apparatus according to claim 3, wherein said first program list is a list written in a text format and said second program list is a list written in a non-text format.

5. A recording method for recording data onto a recording medium, comprising the steps of:

recording a first program list prescribing an order to reproduce data onto said recording medium; and

recording a second program list prescribing the same order to reproduce data as said first program list in a file format different from said first program list onto said recording medium.

6. A recording method according to claim 5, wherein said first program list is a list written in a text format and said second program list is a list written in a non-text format.

7. A reproduction apparatus for reproducing data from a recording medium, comprising:

an optical pickup for radiating a light ray to said recording medium; and

a control microcomputer for controlling said reproducing apparatus,

wherein said control microcomputer controls an operation to reproduce

a first program list prescribing an order to reproduce data or a second program list prescribing the same order to reproduce data as said first program list in a file format different from said first program list by using said optical pickup from said recording medium used for recording said first and second program lists.

8. A reproduction apparatus according to claim 7, wherein said first program list is a list written in a text format and said second program list is a list written in a non-text format.

9. A reproduction method for reproducing data from a recording medium, comprising the steps of:

radiating a light ray to said recording medium; and

detecting said radiated light ray reflected from said recording medium; and

reproducing a first program list prescribing an order to reproduce data or a second program list prescribing the same order to reproduce data as said first program list in a file format different from said first program list from said recording medium used for recording said first and second program lists.

10. A reproduction method according to claim 9, wherein said first program list is a list written in a text format and said second program list is a list written in a non-text format.
