A system controller is provided so as to record the second disk type information having the same content as that of the first disk type information, which is recorded in a DVD-R in advance, in a DVD-R in which the first disk type information is recorded as well as to record the record information in the DVD-R and reproduce the record information only if the first disk type information and the second disk type information have the same contents each other upon reproducing the record information.

Information recording apparatus, recording medium, and information recording method for recording information including characteristic information in correspondence to medium type information

To provide an information recording apparatus and so on which can improve convenience of handling even if music information is encoded in an LPCM system with a high quality and recorded therein. Music information M obtained by encoding a musical composition which should be reproduced in an uncompressed state, first control information Gfor controlling the compressed music information PM, compressed music information PM including a content same as at least any one of the music information M, and second control information Gfor controlling the compressed music information PM, the second control information Gincluding corresponding information RR representing a corresponding relationship between the music information M and the compressed music information PM.

Information recording apparatus and information reproducing apparatus, information recording method and information reproducing method, information recording program and information reproducing program, information recording medium and recording medium

An information processor including a processing device for recording information on a recording medium or reproducing the information recorded on the recording medium, is provided with: an encrypting/decrypting device which is capable of an encrypting operation for encrypting the information to be recorded when the information is recorded on the recording medium and a decrypting operation for decrypting the information to be reproduced from the recording medium when the information is reproduced from the recording medium; the processing device which includes the two or more encrypting/decrypting devices; a control device which controls the encrypting/decrypting device so as to perform one of the encrypting operation and the decrypting operation; and a switching device which switches a transmission path of the information to the encrypting/decrypting device in response to one of the operations performed by the encrypting/decrypting device.

Information processor and information processing method

Method and apparatus for recording/reproducing type information onto/from a plurality of locations on a recording medium, and recording medium having type information recorded thereon at a plurality of locations

An information converting method of converting audio information, which comprises a plurality of partial-audio information based on a predetermined record standard in each of which output control information to control a state of the audio information at a time of outputting the audio information to an external portion is included, into transmission information to be transmitted through a data bus based on a predetermined transmission standard, is provided with: an extracting process of extracting the output control information from each of the partial-audio information; a dividing process of dividing the audio information for each information amount, which is set in advance so as to transmit the transmission information through the data bus, to thereby generate divided-audio information; a generating process of adding the extracted output control information onto the generated divided-audio information to thereby generate an information unit for transmitting the audio information through the data bus; and an outputting process of generating the transmission information by using a plurality of the generated information units and outputting the generated transmission information onto the data bus.
