摘要： The optical disc apparatus of this invention includes: an optical pickup 104 to converge a light beam on an information layer of an optical disc 102; a drive section 105 to move the beam along the radius of the disc 102; a tracking error detecting section 108 for generating a tracking error signal based on a light detection signal; a tracking control section 109 to drive the drive section 105 based on the tracking error signal to make the beam follow tracks on the disc 102; a defect detecting section 124 for detecting, based on the light detection signal and with respect to a preset detection reference level, a fingerprint or a bubble on the disc 102 as a defect to output a defect detection signal; and a waveform shaping section 126 to output a hold signal that holds, in response to the defect detection signal, a signal from the tracking control section 109 at a level just before the defect has occurred. The apparatus is initially operated not to hold the signal from the tracking control section 109 even if there is a defect. But once a tracking failure has occurred during a read operation, settings are changed to hold the signal from the tracking control section 109 against the defect while the read operation is retried.

摘要： To prevent clogging of a nozzle of a printing head, a light irradiator for an ink jet printer is composed of a short arc type discharge lamp (10) and optical elements used for linearly condensing light from the lamp (10), e.g., an elliptic light condensing mirror (20) and a rod lens (30) in order to linearly condense light emitted from the lamp onto a substrate (5). A slit-type light outlet (40) is provided on a bottom plate (60) of a housing (8) so that the direct light from the lamp cannot reach places on the substrate (5) in the vicinity of the nozzle (4) of a printing head (4), and antireflection material (70) is provided on the surface of the bottom plate (60) facing the substrate (5) so that the light emitted from the light irradiator and reflected by the substrate (5) can be absorbed by the antireflection material (70).

摘要： An optical disc drive includes a light source, a lens, a focusing section, a spherical aberration corrector, a focus signal generator, a gain calculator and a processor. The focusing section forms a beam spot in a focusing state on the information storage layer of an optical disc by controlling the position of the lens. The spherical aberration corrector changes a spherical aberration with the beam spot in a focusing state according to a drive value of a driving signal supplied to the spherical aberration corrector. The focus signal generator generates a focus signal representing the focusing state of the beam spot. The gain calculator calculates a loop gain of a focus control system in response to the focus signal. The processor determines the drive value for the spherical aberration corrector by the loop gain.

摘要： An optical disk apparatus according to the present invention includes: a controller 111, which receives an instruction that a layer-to-layer jump be performed from a current layer to a target layer; a layer-to-layer jump control section 146, which adjusts a spherical aberration correction value to the target layer and then gets the layer-to-layer jump attempted; a decision section 146 for determining whether the layer-to-layer jump has been carried out successfully; and a layer determining section 146 for determining, if the focus position has been set on a non-target storage layer as a result of the layer-to-layer jump, where the non-target storage layer is located in the optical disk. The layer-to-layer jump control section 146 shifts the focus position of the light beam from that non-target storage layer to the target layer by reference to information indicating which of the multiple storage layers the non-target storage layer is.

摘要： An optical disc apparatus according to the present invention includes a disc type recognizing section 109 for determining whether the optical disc 100 loaded is a first type, of which the number of information storage layers is less than a setting T (where T is an integer that is greater than two), or a second type, of which the number of information storage layers is equal to or greater than the setting T. Depending on whether the optical disc loaded has turned out to be the first type or the second type, the apparatus decides what to do as the read/write preprocessing (such as whether a fingerprint detection process needs to be performed or not).
