A recording device comprises a recording means () for recording content data on a recordable recording medium () having a first recording layer () including a first data area () and a second recording layer () including a second data area (), a first reading means () for reading the address of the position corresponding to the maximum capacity of the first data area, a second reading means () for reading the address of the layer jump position of the content data, a calculating means for calculating the position at which the recording of the contents data is started such that the layer jump position of the content data is recorded at the position corresponding to the maximum capacity of the first data area, and a first controlling means (); for controlling the recording means such that first padding data is recorded in an area from the start position of the first data area to the position at which the recording of the contents data is started.

Recording device and method, and computer program

User data is recorded onto a DVD by the incremental recording method and by using padding when closing a recording zone, read error data is recorded onto the DVD. The read error data is generated by making a sector error detection code or a PI/PO error correction code in the ECC block different from a correct value.

Information recording device and information recording method generating a copy preventing structure

Disclosed is an information recording medium () 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.

Information recording medium, apparatus and method for recording information, and computer program

An information recording medium () is provided with: a first pre-recording area, in which reproducible preformed information including physical address information is recorded in advance and in which preformed address information assigned in advance is not recorded;

Information recording medium, information recording device and method, information reproducing device and method, information recording/reproducing device and recording method, and computer program

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

Information recording medium, data structure, and recording apparatus

A recording apparatus includes: a recording device for recording record information onto at least one of (i) a recording medium including: a first recording layer and a second recording layer in which the record information is recorded by irradiating laser light thereon, each of the first and second recording layers including a buffer area and a calibration area, and (ii) a recording medium including: the first recording layer and the second recording layer, each of the first and second recording layers including the calibration area; a setting device for setting a reserved area having a predetermined size for extending or generating the buffer area, by each recording unit in the calibration area; a calibrating device for calibrating the power by using the calibration area other than the set reserved area; and a controlling device for controlling the recording device to record the record information into at least the reserved area.

Recording device and recording method, and computer program

In a recording disc, a straight groove () and a position determining pit () are formed in an inner circumference area (), and a straight groove () and an over-run preventing pit () are formed in an outer circumference area (), and only a straight groove () is formed over the entire middle area ().

Recordable type information recording medium, information recording apparatus, and information recording method

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

Optical recording medium having physical and logical position information of buffer areas

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.

Program recording and viewing reservation system and method thereof

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.
