摘要:
A storage medium initializing method includes steps of recording on a storage medium a management table configured to manage a replacement area for a defect area in a data area in the storage medium; recording a unique identification on the storage medium; and recording management data in the data area. The step of recording a unique identification includes recording the unique identification on the storage medium, but outside an area managed by the management data. The method optional includes initialization and cancellation steps.

A recording method includes the steps of causing a first management system retained in a first apparatus to manage a storage medium loaded in a second apparatus when the first apparatus and the second apparatus are connected to one another; and recording the data to the storage medium based on a second management system which is retained in the second apparatus and which limits consecution of data recording segments when it is determined that data transferred from the first apparatus to the second apparatus are to be recorded to the storage medium. A recording apparatus and editing method and apparatus also manage data storage and editing between first and second apparatuses.

A recording method includes the steps of detecting whether unique information is recorded in a storage medium outside a predetermined area managed by a management data that manages data in a data area on a storage medium; generating unique information when in the detecting step no unique information is detected as being recorded in the storage medium; and recording the unique information when generated in the generating step to the storage medium outside the area managed by the management data.

A terminal generates predetermined music information on a reproduced piece of music and reproduction frequency information including a reproduction count of the piece of music. Then, the terminal transmits the reproduction frequency information and its own apparatus ID to a server. When receiving the reproduction frequency information and the apparatus ID, the server computes a similarity coefficient between pieces of music reproduced by the terminal and an other terminal on the basis of the terminals' reproduction frequency information and apparatus IDs. The server then catalogs the computed similarity coefficient on a favorite list by associating the similarity coefficient with the reproduction frequency information's music information and the apparatus IDs. The server also identifies at least a similar piece of music reproduced by the terminal and the other terminal by referring to the favorite list. Finally, the server selects a piece of music reproduced by the other terminal but not reproduced by the terminal among the similar pieces of music. As a result, it is possible to determine a piece of music favorite with the user by executing a simple procedure.

A reproducing method, reproducing apparatus, recording method and recording apparatus provide read/record data in an efficient way to a storage medium. The reproducing method includes the steps of selecting one of a plurality of tracks described in a play order table designating an order of reproduction of the tracks; reading track information corresponding to the selected track from a track information table which includes a coding system and a decryption key corresponding to each track, and a plurality of items of track information each of which has pointer information pointing to one of a plurality of items of part information within a part information table; reading the part information corresponding to the pointer information within the read track information, each of the plurality of items of part information having part pointer information pointing to part of a single audio file; reading that part of the audio file which corresponds to the part pointer information within the read part information; and decrypting the read part of the audio file based on the decryption key and the coding system.

A recording method includes the steps of reading a management table for managing whether data are recorded on a recording medium in units of a first recording segment; detecting whether the first recording segment is associated with a second recording segment smaller than the first recording segment according to a designation of data recording in units of the second recording segment into the recording medium; discriminating from data in the management table whether it is possible to read data of the first recording segment; reading the data in units of the first recording segment and temporarily recording the data to a memory when in the discriminating step it is determined that it is possible to read data in units of the first recording segment; recording data to a part of the first recording segment recorded in the memory in units of the second recording segment; and recording data of the first recording segment that was temporarily recorded in the memory to the storage medium.
摘要:
Decrypting information corresponding to a selected track, file pointer information, and index information are read out from a track information table having the decrypting information corresponding to each track, the file pointer information showing one of a plurality of files with headers, and the index information showing a position in the file. The header of the file with the header is read out on the basis of the file pointer information and position information in the file corresponding to the index information is detected from the header. A part of data of the file is read out on the basis of the position information and the read-out data is decrypted on the basis of the decrypting information.

摘要:
A service body comprises a right server, a content server, and a buddy server. The right server correlatively manages charging information and a unique disc ID of each disc. The content server manages a content that is distributed and information associated therewith. The buddy server correlatively manages a disc ID of an information provider side and a disc ID of an information recipient side. A user loads a disc he or she bought from the service body into a disc drive device, logs in the content distributing server, and obtains information corresponding to the disc ID.

A recording method is responsive to a user-initiated single instruction, that includes the steps of copying content data from a storage medium loaded in a first apparatus to a data storage device of a second apparatus; and setting a predetermined check-out count from a predetermined count to the predetermined count minus one, the predetermined check-out count including control information corresponding to a predetermined number of times the content data is allowed to be copied to the data storage device. A storage medium driving apparatus implements the recording method described above.
