| 20080239913 | ADAPTIVE WRITING METHOD FOR HIGH-DENSITY OPTICAL RECORDING APPARATUS AND CIRCUIT THEREOF - An adaptive writing method of a high-density optical recording apparatus and a circuit thereof. The circuit includes a discriminator for discriminating a magnitude of a present mark of input NRZI data and magnitudes of leading and/or trailing spaces of the input NRZI data, a generator for controlling the waveform of a write pulse in accordance with the magnitude of the present mark of the input NRZI data and the magnitudes of the leading and/or trailing spaces of the input NRZI data to generate an adaptive write pulse, and a driver for driving a light source by converting the adaptive write pulse into a current signal in accordance with driving power levels for respective channels of the adaptive write pulse. The widths of the first and/or last pulses of the write pulse waveform are varied in accordance with the magnitude of the present mark of input NRZI data and the magnitude of the leading and/or trailing spaces, thereby minimizing jitter to enhance system reliability and performance. | 10-02-2008 |

| 20090183903 | Printed circuit board - A printed circuit board print (PCB) having an insulation layer; an intaglio pattern formed by depressing a part of the insulation layer corresponding to a location where a circuit pattern is to be formed; and conductive ink forming the circuit pattern by filling the intaglio pattern. A method of manufacturing the PCB includes providing an imprinting stamper with a relievo pattern formed in correspondence with a circuit pattern data using the circuit pattern data, forming an intaglio pattern corresponding to the relievo pattern by pressing the imprinting stamper on an insulation layer, and forming a circuit pattern by printing conductive ink in the intaglio pattern by an ink-jet method using the circuit pattern data, allows the forming of a circuit pattern to a required thickness by injecting conductive ink in a groove processed by the imprint method, and prevents the spreading of ink and the distortion of the pattern shape in the curing process for conductive ink containing metal. Also, the circuit pattern CAD data used in the manufacturing of an imprinting stamper can be utilized again in the ink-jet printing process. | 07-23-2009 |
