摘要:
A method of recording and reproducing video data is provided. The method of recording video data in an information storage medium includes the steps of (a) decoding originally encoded video data, (b) re-encoding the decoded video data in a different way to the originally encoded video data, (c) generating video transform information which is to be referred to for decoding the video data into its original state, and (d) recording the generated video transform information and the re encoded video data in the information storage medium. Accordingly, the video data can be properly reproduced even if it is re-encoded in a different way to the originally encoded video data.

A nonvolatile memory cell is capable of reducing an excessive current leakage due to a rough surface of a polysilicon and of performing even at a low temperature process by forming the first oxide film including a silicon oxynitride (SiOxNy) layer using nitrous oxide plasma and by forming a plurality of silicon nanocrystals in a nitride film by implanting a silicon nanocrystal on the nitride film by an ion implantation method, and a fabricating method thereof and a memory apparatus including the nonvolatile memory cell.

摘要:
An information storage medium in which speed information has been recorded, and a method of recording and/or reproducing data on the information storage medium. The information storage medium includes a reproduction-only area in which recording speed information and/or reproducing speed information which indicate whether a drive can record and/or reproduce data on the information storage medium are recorded. The method of recording and/or reproducing data in an information storage medium, the method includes: recording, as reproduction-only data in a reproduction-only area, recording speed information and/or reproducing speed information, which is used to indicate speed capabilities to a drive; and recording or reproducing data on the information storage medium when a recording speed or a reproducing speed capability of the drive matches the recording speed information or the reproducing speed information.
摘要:
An information storage medium and an apparatus for recording and/or reproducing the information storage medium are provided to control an optimal recording power without an influence of an optimal power control (OPC) area in a layer upon an OPC area in a different layer. The information storage medium includes at least one information storage layer including an optimal power control area for obtaining an optical recording condition. OPC areas in adjacent information storage layers are disposed within different radiuses of the information storage medium. Accordingly, even when the information storage medium is made eccentric or has a manufacturing error, a recording property of the information storage medium is prevented from being degraded due to an influence of an OPC area in an information storage layer upon an OPC area in an adjacent information storage layer.
摘要:
A recording medium having a spare area for defect management, and a method and apparatus for allocating and assigning the spare area. A plurality of zones are formed as one group without prescribing the relationship between a zone and a group. Spare areas include a spare area for slipping replacement and a spare area for linear replacement. The spare are for slipping replacement is first allocated, and the spare area for linear replacement is allocated according to the size of an area remaining after the spare area for slipping replacement is used and the purpose for which a disc is used. When the spare area for linear replacement becomes deficient during use of the disc, a supplementary spare area for linear replacement is allocated in sequence from the rearmost of a logical file area, such that the spare area can be more flexibly and effectively allocated.

A photosensitive drum unit includes a photosensitive drum, a shutter having a rotation axis shaft which opens and closes to selectively enable access to the photosensitive drum, and a coupler, wherein a linear motion thereof causes a rotational motion of the shutter about the rotation axis shaft. The coupler is coupled to a rotation axis shaft of the shutter and is capable of changing a straight line motion to a rotational motion in a narrow space. In an image forming apparatus equipped with the photosensitive drum unit of the invention, a pressing unit mounted at a support frame of the photosensitive drum unit is pressably engageable with the coupler.
摘要:
A super resolution information storage medium capable of reproducing information recorded thereon as a mark with a size less than the resolution limit of an incident light beam, includes marks of varying sizes recorded thereon, excluding marks with a size in the vicinity of the resolution limit, where the resolution limit depends on the wavelength of a light source irradiating light on the information storage medium and the numerical aperture of an object lens focusing the light irradiated from the light source on the information storage medium. By adjusting the size of or excluding a mark with a size in the vicinity of the limit of the resolution that has a low C/N ratio, the C/N ratio is improved and the performance of super resolution information reproduction is improved such that high density and high capacity information storage medium can be implemented.
摘要:
A recording medium for storing defect management information to record real time data, a defect managing method therefor, and a method of recording real time data. The recording medium stores information representing use or non-use of linear replacement defect management in which a defective area on the recording medium is replaced with the spare area, in order to record real time data. While maintaining compatibility between the defect managing method and a defect managing method based on a current DVD-RAM standard, i.e., while allowing a report of the fact that there are blocks which have not been linearly replaced, linear replacement is not performed when real time data is recorded. Thus, real time data can be recorded and reproduced.
摘要:
An information storage medium having a plurality of information storage layers, each of which includes an optimal power control (OPC) area for obtaining an optimal recording condition, wherein OPC areas in odd-numbered and even-numbered information storage layers are disposed not to face each other and not to contact each other, or partially overlap each other and lock out use of the overlapped portion. Therefore, when an OPC area of one information storage layer performs OPC, this OPC does not affect another information storage layer.

A lightweight cementitious panel/tile is provided with increased bending stiffness and less weight than conventional construction panels. The cementitious panel is constructed of a cementitious surface (which may be reinforced with wood fiber or other materials) supported by an integrated stiffener grid on the underside to absorb stresses and loads.
