Abstract

A content providing technique stores content data 120, sends a program for detecting a drive 35 capable of writing on a removable medium D on a user terminal 30, sends a program for determining whether or not a removable medium D is loaded on the drive 35, sends blocks of content data 120 to the user terminal 30, sends a program for writing blocks of content data 120 successively onto the removable medium D, and stores the sent content data blocks 120 successively onto the removable medium D by the drive 35.

Claims

1-9. -9. (canceled)

10. A content storage medium making method in which a server connected to a specific network sends content data, held in the server in advance, to the network, and a client connected to the network receives the content data sent from the server and writes it onto a removable medium, wherein the method comprises steps of:

determining whether or not the client has a drive capable of writing the content data directly onto a removable medium,

determining whether or not a writable removable medium is loaded on the drive, and

sending the content data to the client depending on the results of the determination;

wherein the server sends blocks of content data, each upon a request from the client, and the blocks of content data sent are successively written on the removable medium to be saved thereon.

11. A computer program for performing the content storage medium making method according to claim 10 on computers.

18. A content providing system according to claim 10, wherein the removable medium is an optical disc writable by the drive.

12. A content providing system comprising:

a server connected to a specific network to send content data, held therein in advance, to the network; and

a client connected to the network to receive content data sent from the server and write it on a removable medium;

wherein the client comprises a drive allowing a removable medium to be loaded thereon to write content data sent from the server on it; and

wherein the server comprises a storage means for storing content data,

a drive detection program for determining whether or not the client has a drive,

a drive detection program sending means for sending the drive detection program to the client,

a removable medium detection program for determining whether or not a writable removable medium is loaded on the drive,

a removable medium detection program sending means for sending the removable medium detection program to the client,

a content data sending means for sending blocks of content data stored in the storage means to the client over the network, each upon a request from the client,

a writing program for writing the blocks of content data each sent by the content data sending means, successively onto a removable medium on the client, thereby saving the content data thereon, and

a writing program sending means for sending the writing program to the client.

13. A content providing system according to claim 12,

wherein the client comprises a fixed medium device incorporated in the client and capable of storing content data thereon;

and

wherein the server further comprises a fixed medium storage prevention program to be executed by the client, which prevents content data received by the client from being written successively on the fixed medium device, thereby preventing the content data from being stored thereon, and

a fixed medium storage prevention program sending means for sending the fixed medium storage prevention program to the client.

19. A content providing system according to claim 12, wherein the removable medium is an optical disc writable by the drive.

21. A content providing system according to claim 13, wherein

the fixed medium storage prevention program includes an improper drive detection program for determining whether or not an improper drive for which writing is prohibited in advance is provided on the client, and

the content providing system includes a writing prohibiting means for prohibiting writing onto a removable medium by the writing program, when the improper drive detection program determines that an improper drive for

which writing is prohibited is provided on the client.

22. A content providing system according to claim 21, wherein

the server comprises a pattern file storage means holding the improper drive detection program for prohibiting an improper drive from writing onto a removable medium, and

a pattern file sending means for sending the improper drive detection program held in the pattern file storage means, to the client;

and

wherein the client comprises a pattern file receiving means for receiving the improper drive detection program for prohibiting an improper drive from writing onto a removable medium, sent by the pattern file sending means.

14. A content providing system comprising:

a server connected to a specific network to send content data, held therein in advance, to the network; and

a client connected to the network to receive content data sent from the server and write it on a removable medium loaded on a drive;

wherein the client comprises a drive detection means for determining whether or not a drive exists, a removable medium detection means for determining whether or not a writable removable medium is loaded on the drive,

a determination result sending means for sending the results of determination to the server providing content by the drive detection means and the removable medium detection means, and

a writing means for writing blocks of content data sent from the server depending on the determination results, each upon a request from the client, successively onto a removable medium, thereby saving the content data thereon.

15. A content providing system according to claim 14,

wherein the client comprises a fixed medium device incorporated in the client and capable of storing content data thereon;

and

wherein the server further comprises a fixed medium storage prevention program to be executed by the client, which prevents blocks of content data each received by the client from being written successively on the fixed medium device, thereby preventing the content data from being stored thereon, and

a fixed medium storage prevention program sending means for sending the fixed medium storage prevention program to the client.

16. A content providing system according to claim 15, wherein

the fixed medium storage prevention program includes an improper drive detection program for determining whether or not an improper drive for which writing is prohibited in advance is provided on the client, and

the content providing system includes a writing prohibiting means for prohibiting writing onto a removable medium by the writing program, when the improper drive detection program determines that an improper drive for which writing is prohibited is provided on the client.

17. A content providing system according to claim 16, wherein

the server comprises a pattern file storage means holding the improper drive detection program for prohibiting an improper drive from writing onto a removable medium, and

a pattern file sending means for sending the improper drive detection program held in the pattern file storage means, to the client;

and

wherein the client comprises a pattern file receiving means for receiving the improper drive detection program for prohibiting an improper drive from writing onto a removable medium, sent by the pattern file sending means.

20. A content providing system according to claim 14, wherein the removable medium is an optical disc writable by the drive.
