Abstract

Index data is automatically formed with respect to music data recorded on a recording medium. In the index data, statuses showing states of the music data such as reproducible data, data which was moved to another recording medium and whose reproduction is inhibited, and deleted data are provided for each music data. The status is changed in association with a change in state of the music data. For example, when the music data which was moved to another recording medium and whose reproduction is inhibited is returned from a move destination, the status is changed so as to indicate a reproducible state. Index data which does not exist on the recording medium can be formed in the outside and newly added. Information of the music data possessed by the user can be managed in a lump by using the index data.

Claims

1. A recording and reproducing apparatus comprising:

receiving means for receiving supplied data and attribute data relating to said supplied data;

accounting means for charging an amount of money for receiving said supplied data;

memory means for storing said supplied data and said attribute data, wherein said attribute data includes status data;

a recording and reproducing unit for recording said supplied data in said memory means and for reproducing said supplied data recorded in said memory means;

transferring means for transferring said supplied data to an external recording/reproducing apparatus; and

control means for attaching a reproduction inhibition flag to said supplied data stored in said memory means when said supplied data is transferred to said external recording/reproducing apparatus, thereby prohibiting reproduction of said transferred data by said recording and reproducing apparatus, and

for deleting said reproduction inhibition flag so that the reproduction of said supplied data is enabled when said transferred supplied data is returned to said recording and reproducing apparatus, and

for rewriting said status data included in said attribute data of said supplied data stored in said memory means when said supplied data stored in said memory means is deleted from said memory means.

2. The apparatus according to claim 1, wherein

when the supplied data stored in said memory means is deleted from said memory means, said control means rewrites the attribute data of the deleted supplied data to attribute data indicating that the deleted supplied data was deleted from said memory means.

3. The apparatus according to claim 1, wherein

when the supplied data reproduced from said memory means is supplied to another equipment and stored in the other equipment, said control means rewrites the attribute data of the supplied data stored in said memory means and reproduced from said memory means.

4. The apparatus according to claim 3, wherein

when the supplied data reproduced from said memory means is stored in the other equipment, said control means inhibits a reproducing operation in said apparatus of the supplied data reproduced from said memory means and stored in the other equipment.

5. The apparatus according to claim 3, wherein

when the supplied data reproduced from said memory means is stored in the other equipment, said control means rewrites a data portion indicative of a storage destination of the supplied data reproduced from said memory means in the attribute data of the supplied data reproduced from said memory means and stored in the other equipment.

6. The apparatus according to claim 1, wherein

said control means controls a recording or reproducing operation of said recording and reproducing unit on a basis of the status data.

7. The apparatus according to claim 6, wherein

when the supplied data reproduced from said memory means is supplied to another equipment and stored in the other equipment, said control means rewrites the status data of the attribute data of the supplied data reproduced from said memory means.

8. The apparatus according to claim 7, wherein

when the status data of the attribute data of the supplied data stored in said memory means indicates that the supplied data obtained by reproducing the supplied data stored in said memory means is the supplied data supplied to the other equipment and stored in the other equipment, said control means inhibits the reproducing operation of said recording and reproducing unit.

9. The apparatus according to claim 1, further comprising

a display unit to display the attribute data of the supplied data stored in said memory means.

10. A recording and reproducing apparatus comprising:

receiving means for receiving supplied data and attribute data relating to said supplied data;

accounting means for charging an amount of money for receiving said supplied data;

memory means for storing said supplied data and said attribute data including status data indicative of a status of said supplied data;

a recording and reproducing unit for recording said supplied data into said memory means and for reproducing said supplied data recorded in said memory means;

transferring means for transferring said supplied data to an external recording/reproducing apparatus; and

control means for controlling an operation of said recording and reproducing unit on a basis of the status data stored in said memory means and for attaching a reproduction inhibition flag to said supplied data stored in said memory means when said supplied data is transferred to said external recording/reproducing apparatus, thereby prohibiting reproduction of said transferred data by said recording and reproducing apparatus, and

for deleting said reproduction inhibition flag so that the reproduction of said supplied data is enabled when said transferred supplied data is returned to said recording and reproducing apparatus, and

for rewriting said status data included in said attribute data of said supplied data stored in said memory means when said supplied data stored in said memory means is deleted from said memory means.

11. The apparatus according to claim 10, wherein

when the supplied data reproduced from said memory means is supplied to another equipment and stored in the other equipment, said control means rewrites the status data of the attribute data of the supplied data stored in said memory means and reproduced from said memory means.

12. The apparatus according to claim 11, wherein

when the supplied data reproduced from said memory means is stored in the other equipment, said control means inhibits a reproducing operation of the supplied data reproduced from said memory means and stored in the other equipment.

13. The apparatus according to claim 11, wherein

when the supplied data reproduced from said memory means is stored in the other equipment, said control means rewrites a data portion indicative of a storage destination of the supplied data reproduced from said memory means in the attribute data of the supplied data reproduced from said memory means and stored in the other equipment.

14. The apparatus according to claim 10, further comprising

a display unit for displaying the attribute data of the supplied data stored in said memory means.
