When the user designates the reproduction of searching audio data, the designated searching audio data and audio volume data are read from a searching data recording portion. The searching audio data is reproduced corresponding to the audio volume data. When the user designates the reproduction of main audio data, the selected audio data is read from a disc and reproduced. In addition, number-of-reproduction-times data, audio volume data, audio quality data, and time period data for the designated main audio data that are updated in the searching data storing portion. The searching audio data corresponding to the designated main audio data is read from the disc corresponding to the audio quality data and the time period data and recorded to the searching data storing portion.

First, an ID added disc is loaded. A disc ID is read from the disc at step S2. The disc ID matches a hardware ID of hardware that can use software recorded on the disc. If the disc ID has not been read from the disc, an error process is performed. At step S3, a hardware ID of hardware connected to a personal computer is obtained. At step S4, it is determined whether or not both the IDs match. When the determined result represents that they match, at step S5, an application starts. When the determined result at step S4 represents that they do not match, at step S6, an error message is displayed on a display of the personal computer.

On a CD-R, a UID that is unique identification information is pre-recorded. When the CD-R is loaded into an information terminal unit, the UID is read and transmitted to a management server through the Internet. The management server determines whether predetermined data can be recorded onto the CD-R in accordance with the received UID. For example, when the UID is valid, contents data is downloaded from the management server to the information terminal unit and recorded onto the CD-R. In addition, for example, when the UID is valid, a notification that represents that contents data is permitted to be copied or moved is transmitted from the management server to the information terminal unit. As a result, contents data recorded on another recording medium can be copied or moved to the CD-R.

A recording medium includes at least a recording area in which pieces of content data are recorded, and a lead-in area in a position that is read before the recording area is read. In one of the recording area and the lead-in area, identification information which indicates whether the recording medium is for a rental use is recorded.

The present invention is a recording medium comprising a lead-in area, a data record area for recording encrypted content data, and a lead-out area, wherein key information for decrypting the encrypted content data is recorded in at least one of the lead-in area and the lead-out area and the program area.
摘要:
A data recording medium on which digital data is recorded eliminates acquisition by a user of a plurality of data recording media for different applications to improve the convenience is provided. Digital data for a plurality of different applications and UIDs as identification information added for the individual applications are recorded on the same data recording medium. For example, a music CD on which data for promotion and data for a normal version are managed with different UIDs from each other is distributed as a CD for promotion. The data for promotion allow free reproduction thereof. If a user tries the music CD and wants to purchase the data for a normal version, then the user would access a server owned or managed by a record company of a distributor of the music CD to perform a charging procedure. This validates the UID with which the data for a normal version is managed, and after the UID is authenticated by the server, reproduction of the full data is permitted.
摘要:
A recording medium is applicable to information service system for receiving and transmitting information when a terminal device on the user's side accesses an administrative server, which is a server device, using a communication line such as the Internet. This recording medium (10a) comprises a lead-in region (16a), a data recording region (14a) positioned on an outer region than the lead-in region, and a lead-out region (12a) positioned on an outer region than the data-recording region. In at least any one of these regions (12a), (14a), and (16a), multiple pieces of identification information are recorded.
摘要:
The present invention provides a content-on-demand system capable of managing users' system-utilization frequencies such as download counts and connection times as well as changing the quality of a content transmitted from a server to a user in dependence on the system-utilization frequency of the user. Thus, a high-quality content or a highly functional content is provided to a user with a high system-utilization frequency. By differentiating contents provided to users in accordance with the system-utilization frequencies of the users, network businesses can be activated.
