20110002202 | METHOD FOR CONTROLLING FOCUS ON LABEL SIDE - A method for controlling focus on a label side of a light-scribe disc divides the label side into several zones, finds the maximum SBAD and the corresponding focus volt and spoke during focusing on each zone, approaches a primary focus volt level curve, compensates a predetermined volt to focus on the label side, checks the maximum SBAD and the corresponding focus volt and spoke between the primary focus volt level curve and the compensation volt on each zone, and approaches a calibrating focus volt level curve to reduce errors. | 01-06-2011 |
20110002210 | METHOD FOR CALIBRATING ACTUATOR - A method for calibrating an actuator is provided. A reflective reference surface is set. An objective lens is shifted to several calibration positions along the tracking direction in the actuator, focusing is performed at each position, and the shift volt and the focus volt are recorded. The focus volt at a calibration position is set as a standard focus volt, and the focus volt bias at the other calibration position with respect to the standard focus volt is calculated. A focus volt bias curve is formed by curve-fitting the focus volt bias and the shift volt at each calibration position, and a focus volt bias is obtained to compensate the volt along the focusing direction. | 01-06-2011 |
20110026388 | METHOD FOR CALIBRATION FOCUSING ERROR SIGNAL OF LIGHTSCRIBE DISC - A method for calibrating a focusing error signal of a lightscribe disc includes the following steps. An optical pickup head is moved to a focusing reference surface by utilizing radial voltages to some predetermined measuring positions to find and record the best gain value used to calibrate the asymmetry of the focusing error signal. The best gain fitting curve is formed by curve-fitting, based on the recorded radial voltages and the best gain values. The best gain value is obtained by an interpolation or extrapolation method, and used to calibrate the asymmetry of the focusing error signal of a lightscribe disc. | 02-03-2011 |

20110051579 | METHOD FOR CALIBRATING SIGNAL OFFSETS ON LIGHTSCRIBE DISC - A method for calibrating signal offsets on a lightscribe disc is provided. Spoke signals of an inner ring are utilized as a counter in order to read information pattern signals of an outer ring in a predetermined marked area. Measure the signal offsets of the information pattern signals. Check whether the number of the spoke signals of the inner ring exceeds a predetermined value. When the number of the spoke signals does not exceed the predetermined value, continue to measure the signal offsets; and when the number of the spoke signals reaches the predetermined value, calculate an average signal offset. The signal offsets of the information pattern signals of the outer ring can be calibrated by utilizing the average signal offset during a radial calibration or a decoding calibration. | 03-03-2011 |
20110222385 | APPARATUS AND METHOD FOR TESTING SPOKE SENSOR - An apparatus and a method for testing spoke sensor are disclosed. A drive unit is started to rotate a test disc to a predetermined rotation speed. A module test unit is electrically connected to a spoke sensor under test of a spindle motor module. The module test unit is started to drive the spoke sensor to detect the spoke signals of the test disc and record the number of detected spoke signals. Within a test time, a comparison unit is used for comparing the number of spoke signals with a threshold, and only when the detected number is larger than a threshold will the spoke sensor be assembled to the product. Thus, the product quality is assured. | 09-15-2011 |
20110228655 | COMPENSATION METHOD IN RADIAL DIRECTION ON LABEL SIDE OF OPTICAL DISC - The disclosure discloses a compensation method in a radial direction on a label side of an optical disc. An optical disc is inserted into an optical disk drive. The data side of the optical disc is divided into at least one compensation area. An optical pick-up head (OPU) is moved from inner to outer rings by simulating a writing process. The OPU is moved to some pre-determined points and radial-directional compensation is performed to obtain radial-directional voltage gains at the pre-determined points. The voltage gains are recorded. The label side of an optical disc is inserted into the optical disk drive. The simulated track number is calculated on the basis of the required moving distance for the OPU to write pattern on the label side. The OPU is moved to write the label side by a radial-directional lens driving voltage compensated with a gain obtained from a compensation formula. | 09-22-2011 |
20140126105 | CAPACITOR STRUCTURE AND PROCESS FOR FABRICATING THE SAME - A process for fabricating a capacitor is described. A template layer including a stack of at least one first layer and at least one second layer is formed over a substrate, wherein the at least one first layer and the at least one second layer have different etching selectivities and are arranged alternately. An opening is formed through the template layer. A wet etching process is performed to recess the at least one first layer relative to the at least one second layer, at the sidewall of the opening. A bottom electrode of the capacitor is formed at the bottom of the opening and on the sidewall of the opening, and then the template layer is removed. | 05-08-2014 |
