摘要： In an optical disk apparatus, by obtaining the temperature in the vicinity of a laser in the apparatus, the power source voltage of the laser driver is controlled such that power consumed by the headroom of the laser driver is reduced to the maximum extent without deteriorating the current drive characteristic of the headroom when the temperature becomes higher. The laser driving current of the laser driver is monitored to control the power source of the laser driver such that the power consumed by the headroom is possibly reduced while maintaining the current drive characteristic of the headroom for the monitored current.

摘要： The present invention aims to, when recording pulse information are transmitted to a laser driver lying over a pickup through an optical disk, reduce the number of transmission paths or lines from a conventional transmission method and avoid degradation of recording performance due to transmission path characteristics upon fastening of a recording speed thereby to provide stable recording performance at high-speed recording. The invention of the present application reduces the number of transmission signals by encoding multi-level laser pulse information transmitted by the laser driver. Further, gray codes are used for encoding to reduce constraints of skew between bits. Furthermore, encoding is executed using each state transition and the state transitions are switched according to each recording mark and space, thereby reducing the occurrence of a short pulse on each transmission path. In addition, the presence or absence of the encoding is switched to enable signal transmission, thereby making it possible to make compatible adaptation to complex laser pulse information and adaptation to high-speed recording.

摘要： The present invention is to realize a proper inner zone layout in a quadruple-layer disk.A test area is provided in the inner zone (inner circumference side area) in each of recording layers. If two test areas closer to the outer circumference, of four test areas, are defined as a first pair and two test areas closer to the inner circumference are defined as a second pair, the test areas of the first pair and the test areas of the second pair are so disposed as to be prevented from overlapping with each other in the layer direction. Two test areas of the first pair have the same consumption direction of the test area, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction. Two test areas of the second pair have the same consumption direction of the test area opposite to the consumption direction of the test area in the first pair, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction.

摘要： The present invention provides a projection display apparatus realizing improved operability at the time of registration adjustment irrespective of a use situation of the apparatus. In the case where misregistration occurs between primary color lights, video signals for three colors are corrected (registration adjustment is performed) so as to reduce the misregistration in accordance with an input adjustment value. An image inverting process is performed on an input video signal so that the image is inverted in a display screen. By a configuration by the user, the image is properly inverted in the display screen. When the image inverting process is performed, an adjustment value, with a sign different from that in the misregistration direction in a coordinate system where the image is not inverted, is input by an operation on the display screen.
