摘要： Even when a data area and a spare area are procured on a recording medium in advance, performs a replacement process for the replacement area only under specific cases where recording for the data area is impossible, so that the recording areas can be efficiently utilized.The recording medium includes a data area and a spare area. The data area is composed of one or more unit areas each having an address assigned thereto. A recording apparatus includes: a processing section for designating an address of a unit area within the data area; and a control section for recording data in a unit area of the designated address. The processing section determines whether data is recorded in a unit area of a first address or not, and depending on a result of determination, designates either the first address or a second address which is within the same data area. If recording of the data to the designated address has failed, the control section records the data to the spare area.

摘要： An information recording apparatus 110 includes a defect list update section 122 for updating a defect list having a defect address registered therein which represents a position of a defect area existing in a user area, and a recording section 113 for recording information on the information recording medium 130 based on the updated defect list. The defect list update section 122 determines whether or not an area designated by the defect address registered in the defect list is a defect area; and when the area designated by the defect address is determined not to be a defect area, the defect list update section 122 deletes the defect address, registered in the defect list, from the defect list.

摘要： In order to determine a laser emission waveform rule for a recording medium, such as a write-once optical disc, the present invention provides an information recording apparatus, an information recording method and an information recording system capable of determining optimal recording conditions by recording data for approximately one rotation, by reproducing the recorded area, by measuring a phase error for each combination of the length of a mark and the length of a space immediately before or after the mark and by changing an emission waveform rule on the basis of the measured phase error.

摘要： In transmission and reception of signals in which audio data and management information used in playback are mingled, such as the data recorded in DVD or other recording media, this is to present means for separating the information into video and audio data and management information used in playback, so that the reception side can make use of various playback functions, such as a playback of original picture and sound information, a change of playback procedure, and a selection of playback information. At the transmission side, the data packet transforming means generates a first packet stream from transmission data. Consequently, the transmission packet generating means inserts packets generated from the playback management information by playback management information packet transforming means into the first packet stream at a specified rate, and generates a second packet stream. This is transmitted by using communication media as designated in IEEE1394 or the like. At the reception side, the signal acquired in the receiving means is separated into a packet stream of data and packets of playback management information in the packet identification means, so that the playback data is restored from the packet stream of data on the basis of the management information.

摘要： A recording apparatus includes a disc recording unit for recording each video section composing a broadcast program onto a rewritable optical disc; an electronic watermark reading unit for reading electronic watermarks embedded into the video section; and a recording flag storing unit for storing a recording flag. If the read electronic watermarks show that recording is permitted, the recording flag is set as “0” to record the next video section. If the read electronic watermarks show that recording is prohibited, the recording flag is set as “1” not to record the next video section. If a broadcast program is newly selected under a condition where the recording of the currently received broadcast program is prohibited, the recording flag is reset to “0” and the first received video section of the newly selected broadcast program is recorded onto the rewritable optical disc.
