    摘要: An apparatus for making a musical database including a converting unit for converting musical information representing a music piece into note data items, each of note data items being a set of values associated with a period of a single sound denoted by a musical note and a scale level of the single sound denoted by the musical note, a position unit for producing position data items for the note data items, the position data items representing positions at which the note data items are positioned in the musical information, a unit for producing an index indicating relationships between the note data items and the position data items, and a storage unit for storing the index. A retrieval apparatus retrieves a string of note data items from a musical database using the index stored in the storage unit.

    摘要: A CD-ROM stores encrypted software. When a user desires to decrypt and install this software, an approval preparatory key is generated by an installer. This approval preparatory key is generated based on time data. When the user informs a center of this approval preparatory key, the center calculates a difference between this approval preparatory key and a decrypting key and vends this calculated result to a user in the form of an approval key. When the user inputs this approval key to an installer, the installer generates a decrypting key by adding the approval preparatory key to the approval key. The installer decrypts the software by this decrypting key and installs the encrypted software into a personal computer system.

    摘要: A method of preventing a fraudulent use of an optical disk having a read-write region and a read-only region, comprising the steps of: writing data for designating the boundary between the read-write region and the read-only region into a predetermined block of the optical disk; reading the data out of the predetermined block prior to the execution of the software recorded on an optical disk as an object of fraudulent use check; reading data out of a block which is assumed to be in the read-only region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-only region into the same block; reading data out of a block which is assumed to be in the read-write region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-write region into the same block; and judging that the optical disk as an object of fraudulent use check is not a fraudulent copy when the data writing operation is impossible in the block in the assumed read-only region but possible in the block in the assumed read-write region.

    摘要: A vendor ID is written to a system area of a write-once optical disk. When the write-once optical disk is loaded onto a write-once disk drive, a control CPU reads the vendor ID. The vendor ID is written into the header of software received through an interface unit. When the software is input to an SD circuit, the control CPU reads the vendor ID. The control CPU compares the vendor ID in the system area of the write-once optical disk with the vendor ID of the header of the software and checks whether or not the two IDs are identical. If the two IDs correspond to each other, the control CPU writes the software to the write-once optical disk.

    摘要: A method of managing files of an interchangeable storage medium having a RAM area defining an independent RAM section and a ROM area defining an independent ROM section, each section having a file management area for storing file management data and a file area for storing files. The method includes reading file management information out of a file management area of the ROM section in response to a request for establishing a section in which the RAM area and the ROM area are mixed, converting the file management information of the ROM section to file management information of the mixed RAM-ROM section, writing the file management information of the mixed RAM-ROM section in a file management area of the mixed section, and managing ROM files and RAM files as files of the mixed section.
