摘要： An intermediate transfer unit is constructed by covering a conductive cylindrical base member of drum-shape with an elastic member of belt-shape, the elastic member of belt-shape being adhesively fixed to the base member with an adhesive agent, grooves or pits being provided on the surface of the cylindrical base member, the elastic member of belt-shape being adhesively fixed by the adhesive agent filled in the grooves or pits. The adhesive agent has a resistivity smaller than at least the resistivity of the elastic member of belt-shape. By doing so, it is possible to construct and keep the uniform distribution of resistivity without change by environment and deterioration with age, and to realize proper transferring. Furthermore, since the diametrical change of the drum due to uneven application of the adhesive agent can be minimized, the effect on misalignment in color can be minimized.

摘要： There are provided an optical disk device and tilt correction processing method for performing recording/reproduction by rapidly acquiring an optimal tilt correction value for an optical disk having a plurality of recording/reproducing layers. In an optical disk device capable of recording or reproducing information by irradiating a laser beam to each of a plurality of recording/reproducing layers of an optical disk, the tilt value is stepwise set within a predetermined range at a predetermined radius position of the recording/reproducing layer located at the farthest distance from the laser beam irradiation side so that an optimal tilt correction value can be obtained from the quadratic function by the method of least squares of the jitter or the like obtained from the disk. By applying the optimal tilt value obtained to the other recording/reproducing layer, it is possible to start recording or reproduction in a short time.

摘要： An optical disk device for recording or reproducing an optical disk has: an objective lens for irradiating a laser beam to the optical disk; an actuator for moving the objective lens in the radial direction of the optical disk; and a spindle motor for rotating the optical disk. After the laser beam irradiated to the optical disk passed through a PID portion of the optical disk, the actuator moves the objective lens in the radial direction of the optical disk at a timing corresponding to a rotational speed. Between signals to drive the actuator, an output time of a deceleration signal is set to a predetermined ratio of a time during which an acceleration signal is outputted. While the deceleration signal is outputted, a light spot passes through the PID portion.

摘要： An optical disk apparatus which can promptly restart reproduction and recording by using a preceding discrimination result of a disk kind without using a memory. A mechanism for correcting an aberration is constructed by an expander lens for the aberration correction and a self-holding element as a moving mechanism of the expander lens. A detector for detecting a position of the expander lens is provided. By detecting a correcting position of the expander lens, the kind of disk to which the reproduction and recording have previously been executed can be discriminated.

摘要： Defocus detection device and method capable of detecting a defocus accurately during recording of information to an optical disk having a plurality of recording layers and an optical disk unit using the device and method are provided. A temporal restriction is imposed on defocus detection and besides, in comparison with a level for detection of a first change of a focus error signal developing during a defocus, a level for detection of a successively occurring second change of a polarity inverse to that of the first change is made to be smaller. When the first level is exceeded and thereafter the second level is exceeded within a restricted time, a defocus is detected.
