An image data obtaining method and apparatus therefore, where the image data obtaining method involves determining an image-capturing mode from among a first image-capturing mode for capturing an image of a target subject by using a filter having a first area for transmitting light and a second area for blocking light, and a second image-capturing mode for capturing the image of the target subject without using the filter; capturing the image of the target subject by selectively using the filter according to the determined image-capturing mode; and processing captured image data.

Image data obtaining method and apparatus therefor

Provided are an optical disc having a plurality of recording layers, and a method and apparatus for recording data thereon. The optical disc has a plurality of recording layers, each recording layer including: a data area; a connecting area; and a remaining area. The data, connecting, and remaining areas are respectively disposed in a direction from an inner circumference of the optical disc to an outer circumference. An outer boundary of each of the data areas is determined according to an amount of data to be recorded. Locations of the connecting areas and the remaining areas are determined by a recording and/or reproducing apparatus according to the determination of the outer boundary of each of the data areas.

Optical disc having plurality of recording layers, and method and apparatus for recording data thereon

A method of reproducing data from an information storage medium having a plurality of recording layers, each layer having a user data area, on which data is recordable by a pickup. A first amount of data is reproduced from a recording layer located closest to the pickup and lesser amounts of data than the first amount of data are reproduced from other ones of the plurality of recording layers. The amount of data reproduced from each of the other ones of the plurality of recording layers progressively decreases from the recording layer closest to the pickup to a recording layer farthest from the pickup.

Information storage medium and method and apparatus for recording/reproducing data on/from the same

An information storage medium and a method and apparatus for recording/reproducing data on/from the information storage medium. The information storage medium includes a plurality of recording layers, each having a user data area, on which data can be recorded by a pickup. Data is recorded in the order of recording layers from closest to farthest from the pickup, and a recordable region in a user data area of a recording layer on which data is to be recorded is smaller than that in a recording layer between the pickup and the recording layer on which data is to be recorded. Each recording layer contains a recordable region in a user data area and a optimum power control (OPC) area in order to maintain the same recording/reproducing characteristics between the plurality of recording layers.

An information storage medium and a recording/reproducing apparatus and method are provided with the ability to extend at least one middle area of an information storage medium comprising two or more recording layers so as to ensure optimal data recording/reproduction. The information storage medium comprises a plurality of recording layers, each including a user data area for recording user data and at least one middle area used by a recording/reproducing apparatus that records/reproduces data on the information storage medium to move among two recording layers, wherein the at least one middle area is extended when the information storage medium is finalized. As a result, when an information storage medium that contains an OPC area for obtaining optimum recording conditions (such as recording power) in an outer circumference thereof is finalized, and if a middle area of the disk is not large enough, the middle area can flexibly be extended.

Information storage medium, and recording/reproducing apparatus and recording/reproducing method

An apparatus for recording data on an information storage medium including a plurality of recording layers, each having a user data area, on which data is recordable by a pickup. Data is recorded in the order of recording layers from closest to farthest from the pickup, and a recordable region in a user data area of a recording layer on which data is to be recorded is smaller than that in a recording layer between the pickup and the recording layer on which data is to be recorded. Each recording layer contains a recordable region in a user data area and a optimum power control (OPC) area in order to maintain the same recording/reproducing characteristics between the plurality of recording layers.

A recording method, a recording apparatus, and an optical recording medium that can improve quality of a signal reproduced from a high multi-speed recording medium. The recording method includes generating a box type recording pattern including a first pulse, which has a duration determined according to a length of a recording mark and which has a first power level, and a second pulse which has a second power level different from that of the first power level, and recording data according to the box type recording pattern.

Recording method to generate a box type recording pattern with a first pulse having a first power level and a second pulse having a second power level, and recording apparatus, and optical recording medium for the same

Provided are a recording/reproducing apparatus and method for optimizing data recording. The recording/reproducing apparatus sets a predetermined length which is an integer multiple of a unit recording length and sets a plurality of recording parameters, with reference to mark/space combinations which can be configured within the predetermined length ahead of a start point of a mark for recording data and mark/space combinations which can be configured within the predetermined length behind an end point of the mark for recording data. Accordingly, by setting a predetermined length and limiting conditions for optimizing recording parameters, and considering run-length combinations which can be configured within the predetermined length, it is possible to quickly and efficiently optimize parameters.

Recording/reproducing apparatus and method

A method of recording and/or reproducing data on and/or from an information recording medium including a compatibility information area in which compatibility information, which specifies whether each area on the information recording medium is recordable and/or reproducible, is recorded, the method includes reading the compatibility information, which specifies whether each area on the information recording medium is recordable and/or reproducible; and recording and/or reproducing the data on and/or from the information recording medium with reference to the compatibility information, wherein if other write protection forms of the information recording medium exist, write protection of the information recording medium is determined, based on a result of performing an OR function on the compatibility information and the other write protection forms.

Recording areas in an optical disc having a plurality of recording layers allocated so each recording layer includes a data area for recording data, a connection area in which a predetermined pattern of data for indicating that no data area is recorded therein, and a remaining area, wherein a size and location of the data area of each recording layer is determined according to an amount of user data to be recorded. The connection area and the remaining area are allocated next to the data area of each recording layer in a direction from the inner circumference to the outer circumference of the disc. Accordingly, a recording time is reducible, and exclusive areas for recording information except user data can be additionally allocated to outer circumference areas of the optical disc or the sizes of the exclusive areas can be increased, increasing recording medium efficiency.
