Data recording medium, data reproducing method and reproducing device, and data processing system

A data recording medium having recorded thereon in advance:

• first digital data including at least work data;
• second digital data recorded by a different recording method than a recording method used to record the first digital data;
• and
• identification information for identifying the individual recording medium, wherein the identification information is recorded in an area on an outer side of a lead-out area provided on an outer side of a data recording area where the first and/or second digital data is recorded.

A data recording medium having recorded thereon in advance:

• first digital data including at least work data;
• second digital data recorded by a different recording method than a recording method used to record the first digital data;
• and
• identification information for identifying the individual recording medium, wherein the second digital data includes information for connecting to a communication network.

A data recording medium having recorded thereon in advance:

• first digital data including at least work data;
• second digital data recorded by a different recording method than a recording method used to record the first digital data;
• and
• identification information for identifying the individual recording medium, wherein the second digital data includes information for connecting to a portable telephone.

A data processing system comprising:

• a data recording medium having recorded thereon digital data including at least work data and having recorded thereon in advance of the work data identification information identifying an individual recording medium;
• information providing means for providing a duplicate recording medium obtained by duplicating at least the digital data recorded on the data recording medium and then adding information provider identification information to the duplicated digital data;
• reproducing means for reproducing the digital data having the information provider identification information added thereto, recorded on the duplicate recording medium;
• and
• work data managing means to which the information provider identification information generated by the information providing means and the information provider identification information recorded on the duplicate recording medium and reproduced by the reproducing means are transmitted.

A data processing system comprising:

• information providing means for providing information obtained by duplicating at least digital recorded on a data recording medium having recorded thereon the digital data including at least work data and having recorded thereon in advance of the work data identification information identifying an individual recording medium and discrimination information indicating a presence/absence of the identification information, and then by adding information provider identification information to the duplicated digital data:
• access means for accessing the information providing means to download at least the digital data duplicated from the data recording medium, having the information provider identification information added thereto and recorded in the information providing means;
• and
• work data managing means to which the information provider identification information generated by the information providing means and the information provider identification information downloaded by the access means are transmitted.

An information transmitting device comprising:

• at least one terminal section for reproducing a recording medium having recorded thereon first digital data related to a work and second digital data including identification information identifying an individual recording medium and address data indicating a homepage address;
• and
• at least one server section connected to the terminal section via a communication channel and designated by the address data
• wherein the server section identifies the identification information of the recording medium supplied from at least the terminal section via the communication channel, and permits downloading of the digital data related to the work to the terminal section when the result of identification indicates that the terminal section is a predetermined kind of terminal section.

An information transmitting method comprising the steps of:

• transmitting identification information of a recording medium from at least one terminal section for reproducing the recording medium having recorded thereon first digital data related to a work and second digital data including at least identification information identifying an individual recording medium and address data indicating a homepage address, to a server section via a communication channel;
• identifying the transmitted identification information by the server section;
• and
• permitting, by the server section, downloading of the digital data related to the work to the terminal section when a result of identification indicates that the terminal section is a predetermined kind of terminal section.

An information transmitting method comprising the steps of:

• transmitting identification information of a recording medium from at least one terminal section for reproducing a duplicate recording medium duplicated from the recording medium having recorded thereon first digital data related to an encrypted work and second digital data including at least identification information identifying an individual recording medium, to a host section via a communication channel;
• authenticating the transmitted identification information by the host section;
• requesting the terminal section for accounting;
• and
• transmitting data related to a key for decrypting the encryption of the first digital data to the terminal section when the accounting is carried out.

An information transmitting method comprising the steps of:

• downloading first digital data together with second digital data by at least one terminal section and duplicating the first digital data, the first digital data being duplicated from a recording medium having recorded thereon at least the first digital data related to an encrypted work and the second digital data including data identification information of at least the first digital data and identification information identifying an individual recording medium, the first digital data being laid open to the public so that the first digital data can be downloaded together with the second digital data to users via a communication channel;
• transmitting the downloaded identification information of the recording medium together with the duplicated first digital data from the terminal section to a host section via the communication channel;
• authenticating the transmitted identification information by the host section;
• requesting the terminal section for an accounting;
• and
• transmitting data related to a key for decrypting the encryption of the first digital data to the terminal section when the accounting is carried out.
