Abstract: Recording sections configured to record titles on a disk based on a management method in which additional recording and erasing of each title is possible, and each of the titles are recorded consecutively in a recording region, and the recorded each title is managed by a manager table which corresponds with the title candidate attached before the finalizing processing is carried out, the start position, and size, and in the case where a recorded title is erased, the region where erasure has been done becomes a recordable empty region and reference to the start position and size from the title candidate of the erased title becomes impossible on the manager table, and a first control section configured to designate the appropriate empty region for recording the title for which reserve recording is requested, from the empty regions present on the disk when the reserve recording of the title on the disk has been requested.

Abstract: In a recording/reproducing apparatus capable of communicating with a data transmission site and the other apparatus through a network, a control unit controls the recording and reproducing of the information based on firmware. A receiving unit receives first information from the other apparatus through the network, the first information including a request of updating of the firmware. An output unit outputs second information to the data transmission site through the network in response to reception of the first information, the second information including a request of transmitting third information used for updating the firmware. A unit acquires the third information from data transmission site through the network to update the firmware.

Abstract: A disk reproducing apparatus comprises a disk reproducing unit configured to reproduce a disk having a recording management area in which an RZone having navigation data is allocated at a head thereof, a plurality of titles are then recorded in a mode in which there is allocated an RZone having presentation data managed by the navigation data, and position information on the RZone is recorded, and a reproduction control unit configured to store position information on the RZone having the navigation data as information indicating a start position of the title and to use the stored information as a title reproduction start position.

Abstract: Defective areas are detected from a medium, and recordable continuous areas are also detected. The sizes of the recordable continuous areas are compared with those of recording data of a recording unit, and a recordable continuous area is determined that has a size equal to or larger than the data size of the recording data of the recording unit and serves as a recording destination of the recording data. Based on this determination, position information indicating that the recording data of the recording unit is recorded on the determined recordable continuous area is recorded on a specific area of the information recording area, and the recording data of the recording unit is recorded on the determined recordable continuous area.

Abstract: A disc reproducing aparatus is provided which is able to read out all of the data stored on the disc in a short time. The disk reproducing apparatus reproduces data stored on a disc and comprise a device for rotating the disc and a data processing device having a plurality of optical pickup devices for reading the data from the rotating disc, such that each pickup device reads a different part of the data area.
