    Abstract: An optical disc apparatus has: a spherical aberration correction unit (7) which corrects the spherical aberration generated in a light spot on a recording layer; a control unit (52) which focuses a light beam on a predetermined recording layer, and shifts the focal point position of the light beam from the current recording layer to another recording layer; and a focus jump control unit (60) which controls correction of spherical aberration and shift of the focal point position based on the interlayer distance between the current recording layer and a recording layer which adjoins in a direction opposite to a direction of shifting the focal point position of the light beam. By this configuration, focus jump is stably executed.

    Abstract: An optical disk device includes a DPDTE signal generating section that detects misalignment between a light spot and a mark or a pit, an FE signal generating section, an optical crosstalk correcting section which corrects a signal output by the FE signal generating section using the DPDTE signal generating section, and a focus control section which controls an actuator so that a light beam converges on an information layer. The DPDTE signal generating section detects the misalignment on the basis of phase information obtained from signals received from predetermined light receiving areas. The optical crosstalk correcting section performs a correcting operation of removing a signal component from predetermined receiving areas of a detector which component is used for a DPDTE signal, the signal component being contained in the signals from the predetermined light receiving areas of the detector which signals are used by the FE signal generating section.

    Abstract: A rod- or plate-shaped light guide includes a first end that receives illuminating light incident thereon, a bottom surface having a reflecting portion thereon for reflecting the light, an emitting face which emits the reflected light, and a protruding portion protruding longitudinally and continuously from the light guide at a second end thereof. The protruding portion has a reduced peripheral dimension compared to a peripheral dimension of an adjacent portion of the light guide, and a reflective body is provided on the protruding portion and covers a longitudinal end face of the protruding portion extending perpendicular to the emitting face. When viewed along an axial direction of the light guide, the reflective body does not jut out from an end face of the light guide even when the body wraps on to a side surface of the protruding portion or expansion occurs.

    Abstract: A rod-shaped light guide which does not cause unevenness in color at the portion near an incident face is produced by injection-molding transparent resin such as acryl and its surfaces include a light-emitting surface, a bottom face, left and right sides and end faces. One end face opposes a light emitting unit, and light scattering patterns for scattering light incident from the end face are formed on the bottom face. The light scattering patterns are different in shape between a portion near the end face as the incident face and a portion away from the end face. The light scattering patterns formed at the portion near the incident face are composed of a large number of fine hemispherical concaves, whereas the light scattering patterns at the portion away from the incident face are composed of triangular grooves or half cylindrical grooves, and the axial direction of these triangular grooves or half cylindrical grooves is equal to coincides with the width direction (sub-scanning direction) of the bottom face on which the patterns are formed.

    Abstract: A line-illuminating device which is resistant to shrinkage problems caused by repetition of heating and cooling includes a white casing made of polycarbonate or the like, a light guide made of an acrylic resin or the like and accommodated in the casing such that the light-emitting surface thereof is exposed, and light-emitting elements (for example, light-emitting diodes) as a light source provided on both ends of the casing so as to abut against the end surfaces of the light guide without a gap. The casing is divided into two portions in the longitudinal direction, and a gap is formed between the two divided portions. With this gap, even if the light guide shrinks due to repetition of heating and cooling, the divided portions can effectively shrink together with the light guide via the gap, and the abutting state between the end surface of the light guide and the light-emitting element can be maintained.
