摘要： A second tracking error detector detects the displacement between the track and the light beam and outputs a second displacement detection result based on the comparison of the reproduction signals between first and second pit strings respectively. A second tracking error controller corrects a target position for push-pull control based on the second displacement detection result. A third tracking error controller calculates a correction data of a first displacement detection result based on the correction amount of the target position by the second tracking error controller, and corrects the first displacement detection result based on the calculated correction data.

摘要： A disk access device records to and plays back from a disk on which data recording is performed according to the ZCLV format, and includes a head that reads/writes data from/to the disk. The disk access device calculates a deferment time period that begins upon completion of data reading/writing in the user area of a currently accessed zone and ends when the head enters a predetermined area of the guard track zone following the user area, and a setting time period for performing settings for data reading/writing in the zone to be accessed next. If the deferment time period is shorter than the setting time period, the disk access device moves the head back, when data reading or writing in the currently accessed zone ends, to a position such that the setting time period ends before the head advancing from the position arrives at the predetermined area.

摘要： The reflected light amount acquiring process acquires the reflected light amount of a laser beam with which a color changeable layer is irradiated from at least one irradiation position included in a predetermined drawing determination area, where the color changeable layer is formed on a label side of an optical disc and changes in color due to heat or light. The operation process compares the reflected light amount acquired from the at least one irradiation position by the reflected light amount acquiring process with a predetermined threshold value to determine whether or not the drawing determination area is suitable for formation of a visible image.

摘要： A self-luminescent indicator which may be employed in a tachometer, a speedometer, or other such gauges in automotive vehicles. The self-luminescent indicator comprises an indicating pointer, a luminescent element, and a semitransparent member. The indicating pointer includes a housing and a cover. The housing has formed therein a groove. The luminescent element is disposed in the groove of the housing. The semitransparent member is arranged within the cover of the indicating pointer for diffusing light emitted from the luminescent element out of the indicating pointer. The semitransparent member has side walls extending substantially parallel to each other in a vertical direction parallel to a given optical path of the luminescent element. With this arrangement, the indicating pointer projects light having uniform and high brightness to an observer without having the light experience total reflection in the semitransparent member so as to improve the visibility of pointer deflection over a dial plate.
