摘要： In a successive approximation-type A/D converter, an S/H circuit samples and holds an analog input voltage. A D/A converter section receives current digital data corresponding to a current search voltage range, and outputs a plurality of comparison voltages based on the current digital data. A comparator section performs parallel comparison in which the held analog input voltage is compared with each of the plurality of comparison voltages. A successive approximation register section outputs digital data for a next search voltage range within the current search voltage range as the current digital data to the digital-to-analog converter section based on a result of the parallel comparison using the current search voltage range. A timing control circuit generates a switching signal from the parallel comparison to a redundant comparison such that the redundant comparison is performed.

摘要： A fixture plate is fixed by a screw onto an optical housing of the optical head device at a portion corresponding to where a monitor signal path portion and an act signal path portion are arranged overlapping one another. The two signal path portions are portions of two types of signal paths discretely formed on a flexible wiring board. The fixture plate is composed of a conductive material. One of the monitor signal path portion and the act signal path portion is covered by the fixture plate and fixed by a screw onto the optical housing together with the fixture plate, while the other of the monitor signal path portion and the act signal path portion is hooked in place by a hook provided on the fixture plate. The fixture plate is interposed between the monitor signal path portion and the act signal path portion.

摘要： The height of a tracking coil in an objective lens driving device having a cover over a magnetic circuit is freed from limitations imposed by the cover, so that an effective length of the tracking coil can be ensured. Magnets 2, 3 generating an effective flux and facing yokes 6, 7 facing the magnets are provided such that effective edges of a focusing coil 12 and a tracking coil 13 are located in an air gap. A cover 19 is provided over the top surface of the magnets 2, 3 and the facing yokes 6, 7. The cover 19 has a notch formed for exposing the tracking coil 13 so as to avoid limiting the height of the tracking coil 13, thereby securing an appropriate effective length of the tracking coil 13 within the effective flux.
