Recording medium, information transmission method, terminal, server, and recording method

An information transmission method, comprising:

• transmitting, from a terminal device to a server device, medium information read out of a recording medium, said recording medium comprising a lead-in region, a recording region in which information is recorded, and a lead-out region, wherein medium information including medium identification information is recorded in at least any one of the lead-in region, the recording region, and the lead-out region, the medium identification information including user identification information that is accessible by a user, wherein said user identification information relates to information used for determining whether or not contents-data are to be received by the user, and wherein said medium information includes a serial number peculiar to said medium, and said user identification information consists of a part of said serial number;
• causing the server device to verify the transmitted medium information for authenticating it;
• and
• while performing check processing on the user identification information when the transmitted medium information is authenticated properly, controlling information transmission to the terminal device on the basis of a result of the check processing.

A terminal device, comprising:

• a head portion for reading out information recorded on a recording medium, said recording medium comprising a lead-in region, a recording region in which information is recorded, and a lead-out region, wherein medium information including medium identification information is recorded in at least any one of the lead-in region, the recording region, and the lead-out region, the medium identification information including user identification information that is accessible by a user, wherein said user identification information relates to information used for determining whether or not contents-data are to be received by the user, and wherein said medium information includes a serial number peculiar to said medium, and said user identification information consists of a part of said serial number;
• a decode processing portion configured to perform decode processing on an output signal provided from the head portion;
• an extraction portion configured to extract the medium information from an output signal provided from the decode processing portion;
• a transmission-and-reception portion configured to transmit the medium information extracted by this extraction portion and to receive information transmitted from an outside device;
• and
• a control portion configured to perform an operation control based on the information read out of the lead-in region of the recording medium by the head portion and the information received by the transmission-and-reception portion, and allowing to cause the user identification information read out of the recording medium by the head portion to be displayed.

A server device, comprising:

• a transmission-and-reception portion for receiving medium information transmitted after being read out of a recording medium by a terminal device and transmitting information, said recording medium comprising a lead-in region, a recording region in which information is recorded, and a lead-out region, wherein at least medium identification information is recorded in at least any one of the lead-in region, the recording region, and the lead-out region, said medium identification information including user identification information that is accessible by a user, wherein said user identification information relates to information used for determining whether or not contents-data are to be received by the user, and wherein said medium information includes a serial number peculiar to said medium, and said user identification information consists of a part of said serial number;
• a storage portion in which at least administrative information including the medium information is stored;
• and
• a control portion for authenticating the medium information received based on the medium information received by the transmission-and-reception portion and the medium information stored in the storage portion, for allowing check processing of the user identification information to be performed when the received medium information is authenticated properly, and for controlling information transmission operation to the terminal device on the basis of a result of check processing.

A recording method, comprising:

• recording medium information including medium identification information, said medium identification information including user identification information that is accessible by a user, in at least any one of a lead-in region, a recording region, and a lead-out region of a recording medium, said recording medium comprising a disc substrate in whose one surface a plurality of irregular patterns based on information is formed, a reflection film formed on the one surface of the disc substrate, and a protection film for protecting this reflection film as well as the lead-in region, the recording region in which the above-mentioned information is recorded, and the lead-out region,
• wherein said user identification information relates to information used for determining whether or not contents-data are to be received by the user;
• and
• said medium information includes a serial number peculiar to said medium, and said user identification information consists of a part of said serial number.
