Abstract: An optical disk (100) comprises recording management areas (103, 113) in which record management data for managing data recording is recorded. The record management data includes (i) physical position information (122, 125, 126) indicating the positions of physical buffer areas in which buffer data for buffering recording operation is physically recorded and (ii) logical position information (121) indicating the position of a logical buffer area in which buffer data is logically recorded or to be recorded.

Abstract: A video object (26) contains a cell (31) which can be appropriately read and reproduced and a dummy cell (32) which cannot be appropriately read or reproduced. Video title set information (21) contains a plurality of program chains (40) containing a real program chain not specifying the dummy cell (32) and a virtual program chain specifying the dummy cell (32).

Abstract: Disclosed is an information recording medium (100) comprising a first recording layer (L0 layer) which is provided with a first recording track for recording record information, and a second recording layer (L1 layer) which is provided with a second recording track for recording record information. Each recording zone (zone #n) including one recording area in the first recording layer and another recording area in the second recording layer which is opposite to the recording area in the first recording layer has a management information recording area (RMA) for recording management information (RMD) for recording the record information.

Abstract: A method for reserving recording and viewing a broadcast program on a display screen includes the steps of extracting a broadcast program timetable; simultaneously displaying the broadcast program timetable and a viewing reservation timetable; waiting for a selection input to select a broadcast program on the display screen; waiting for an allocation input to allocate a selected program into the viewing reservation timetable; and generating recording instruction to instruct recording of the selected program and reproduction reservation instruction to instruct reproduction of the selected program at a time corresponding to a position at which the selected program is allocated in the viewing reservation timetable.

Abstract: A recording apparatus (200) is provided with: a recording device (351) for recording record information with a variable recording power; a recording control device (354) for controlling the recording device to record the record information to be adjacent to an unrecorded portion; a power controlling device (361) for controlling the recording power such that the recording power in recording the record information which is recorded adjacent to the unrecorded portion is weaker than the recording power in recording the record information other than the record information which is recorded adjacent to the unrecorded portion; and an overwrite controlling device (362) for controlling the recording device to overwrite the recorded portion adjacent to the unrecorded portion with overwrite information in which a ratio of presence of a mark signal component is smaller than a ratio of presence of a space signal component.

Abstract: There are provided an information write device and an information read device enabling to generate highly accurate contrast signals. When a main light spot Pc is located at the center of the a groove G, the light spot Pc and sub light spots Psa, Psb are each adapted to radiate a disc DSC such that the sub light spots Psa, Psb radiate positions displaced from the center of the land L. The reflected beams of light from the disc DSC caused by the radiation with the light spots Pc, Psa, Psb are detected to generate push-pull signals each corresponding to the light spots Pc, Psa, Psb, respectively, in accordance with each of the detected signals. Furthermore, a signal to be obtained by amplifying an addition signal, given by adding the push-pull signals each corresponding to the sub light spots Psa, Psb, with a predetermined amplification factor K/n, and a push-pull signal corresponding to the main light spot Pc are added to thereby generate a contrast signal.

Abstract: A plurality of programs are broadcast from at least one station. A system for preparing a program viewing schedule includes a program guide extractor for extracting a broadcast program guide. The broadcast program guide includes program characteristic data. The system also includes a frequency data generator for generating frequency data with regard to the program characteristic data, based on a program viewing history and/or a program recording history. A recorded program data extractor of the system extracts recorded program data. The recorded program data includes a time needed to record each program. A broadcast program allocator of the system selects a program from the broadcast program guide, based on the frequency data, and allocates the selected program in the program viewing schedule. A recorded program allocator of the system determines which program has not been viewed among the recorded programs, and allocates the unwatched program into a vacant area in the program viewing schedule.

Abstract: A television signal of a certain TV program is captured for a specified period and memorized in an image memory as a representative image of that TV program. The representative image is read from the image memory when, for example, the same kind of the TV program is found in a TV listing (list of scheduled programs). The representative image is then attached to the program title in the TV listing. Since the representative image presents visual information, a user can learn more about a scheduled program from the TV listing.
