Abstract: The present invention relates to uncooled infrared detector with infrared absorption structure in which the supporting layer, detection layer, protecting layer, and dielectric layer construct ?/4 resonating absorbtion structure as a single body. In order to enhance the characteristic of uncooled infrared detector, it is essential for the infrared absorption layer to absorb incident infrared with high efficiency. The present invention is characterized in that the infrared detector with unified absorption layer includes an infrared detection film, a device protecting layer, a supporting layer for thermally isolated structure, and a dielectric layer, etc. in its absorption structure. Due to this characteristic, highly efficient infrared absorption is possible with much less thermal mass than the absorption layer for the structure of existing metal/dielectric/metal structure and regardless of the distortion of floating structure caused by fabrication fault rather than air cavity ?/4 structure.

The method includes the steps of providing a three dimensional object including a plurality of substituting surfaces for substituting the stored pictures, bringing the three dimensional object to display the stored pictures, selecting a picture to be displayed among the stored pictures and substituting the picture for a substituting surface, according to an input of a predetermined movement key for front or rear movement of the stored pictures, and performing a preset animation display of the three dimensional object. The stored picture display operations of the mobile communication terminal are performed by using a three dimensional manner and through a proper animation, and the movement between the stored pictures is easier.

Abstract: The present invention relates to an oxide thin film for a bolometer-type uncooled infrared detector having high sensitivity. A vanadium tungsten oxide (V—W—Ox), i.e. a tungsten-doped vanadium oxide, is provided as an oxide film for a bolometer. An oxide for bolometer having characteristics of low resistance of 5 to 200 k? and variable TCR between ?1.5 and ?4.1%/° C. can be obtained by an oxidation of vanadium-tungsten metal film at a low temperature around 300° C., with changing a tungsten content and oxidation time. And a reproducible thin film can be fabricated by low price equipment for thin film deposition, without expensive ion beam or laser apparatus. Accordingly, an oxide for bolometer having characteristics of resistance lower than 100 k? and TCR higher than ?3%/° C. can be obtained with reproducibility, whereby an uncooled-type infrared detector having high sensitivity can be fabricated.

Abstract: A recording medium and a spare area management method for an optical recording medium are provided. The spare area management method utilizes an identification information to indicate whether a primary spare area is full or a supplementary spare area has been assigned or extended, as necessary. The spare area management method improves the performance of the driver by replacing a defective block with a spare block nearer to the defective block.

Abstract: The present invention relates to apparatus and method of determining an optimal writing power for an aged writable disk after checking whether a writable disk is aged or not. The present invention reads signals written on a writable disk, judges whether or not the writable disk is aged based on a signal characteristic, e.g., a level difference between the read signals before and after an equalization and jitter of the read signals, and conducts an OPC at least twice for the writable disk to obtain a precise optimal writing power if judged to be aged. The precise optimal writing power can prevent deterioration of reproduction characteristic of recorded data even though an aged writable disk is used.

Abstract: The present invention relates to an apparatus of measuring how much an eccentricity affects each phase of a disk and controlling disk tracking based on the each effect rate. The present apparatus with disk phase identifying means stores information on dense/sparse state of a tracking error (TE) signal in connection with characteristic of an output signal from said means while a tracking servo is inactivated, and, in data reproduction mode, it identifies a current disk phase based on characteristic of the output signal from said means, and adjusts tracking characteristic of the tracking servo based on the stored information in connection with signal characteristic in order to compensate effect rate of eccentricity on the identified disk phase. Through minute adjustment of servo characteristic for each disk phase, error range of TE signal to track in real time is reduced, whereby, tracking for an eccentric disk becomes easier and more reliable.

Abstract: A method for protecting disc copy of the present invention includes the steps of detecting an identifier of a disc to be reproduced and determining if a disc copy is permitted or not using copy protection disc information and the identifier. A recording and reproducing apparatus having a disc copy-protection function of the present invention includes a reproducing drive for reading data from a disc, a recording drive for writing data on other disc, storage unit for storing a copy-protection disc information for judging whether a disc copy is permitted or not, and control unit for controlling a disc copy from the disc in the reproducing drive to the other disc in the recording drive.

Abstract: The present invention relates to a method of recording data onto an optical disk using a write strategy that corresponds to the recording features of the optical disk. The present method detects a track pitch or storage capacity of a recording medium, adjusts a write strategy according to the detected track pitch or storage capacity wherein the write strategy has been chosen to correspond to the manufacturer of the recording medium, and records input data onto the recording medium using the adjusted write strategy. Accordingly, data quality during later reproduction is improved even though it is recorded onto a non-standard disk that is larger in capacity than the standard.
