Abstract: PROBLEM TO BE SOLVED: To enhance original value by performing a processing so that only the owner of original contents data can possess additional contents data such as jacket, lyric sheet, liner notes. SOLUTION: In this method, record restriction or reproduction permission is individually applied to main contents data such as music data and additional contents data such as jacket, lyric sheet, liner notes appendant thereto. That is, recording is permitted to main contents M and recording is inhibited to additional data L, J, C, N, V. Thus the processing so that only the owner of original contents data can possess the additional contents data such as jacket, lyric sheet, liner notes can be performed and the original value can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To provide a cordial service to a frequent user, for example, through an Internet shopping which is popular in a general market. SOLUTION: When a request for contents data is issued from a user side, a server device or an information center side judges the frequency of use of the user based on fixed data and the received user identification information, and decides whether or not only main data should be transmitted or the main data to which sub-data are attached should be transmitted as the contents data according to the judged frequency of use.

Abstract: PURPOSE:To discriminate the type of a disk without a complicated constitution by a method wherein a recording medium is discriminated on the basis of the detection result of a reflected light flux from a type indication part on the recording medium. CONSTITUTION:A groove 2 is formed in the inner circumferential part of a signal write and readout face la on an optical disk 1 for both write and readout use. It is used as a disk-type indication part. A protruding and recessed pattern is formed in the groove 2. When the groove 2 which is formed between a signal recording region and a chucking hole 1b and which is formed so as to surround the whole circumference of the hole 1b is irradiated with a laser beam flux for readout use, the laser beam flux is refracted and the light intensity of a reflected light flux is stronger in the mirror-face region around the hole 1b. A change in the light intensity is detected, a piece of information is read out and a medium can be discriminated.

Abstract: PURPOSE:To simplify the constitution of the device by dividing a signal recording part into regions where the linear recording density are almost equal throughout the area from the inner periphery to outer periphery, and housing those of a signal recording/reproducing part which is provided with a disk of prescrived storaeg amount with the specific diameter, a loading device, and a controller, in an enclosure having the size smaller than a specific dimension. CONSTITUTION:In the signal recording/reproducing part, the signal recording part is divided into plural signal recording regions where the linear recording density are almost equal each other throughout the area from the inner periphery to outer periphery, and an information signal is recorded and/or reproduced by using the disk 102 housed in a cartridge, having the storage capacity of about 430MB with the diameter of 86mm. These composed parts are housed in the enclosure 1, the dimensions of which are
