摘要： A light refracting element formed in parallel plate shape is attached to a support shaft of a mirror holder, a semiconductor laser and a PSD are disposed at positions between which the light refracting element is sandwiched. The light refracting element is rotated by rotation of the mirror holder, and whereby a laser beam irradiation position is changed on a light acceptance surface of PSD. The laser beam irradiation position on a light acceptance surface corresponds to the mirror rotation position, so that the mirror rotation position and a laser beam scanning position in a target area can be detected based on an output from the PSD.

摘要： A beam irradiation device is provided with a laser light source which emits laser light, a mirror actuator which causes the laser light to scan a targeted area, and an emission window through which laser light reflected on a mirror of the mirror actuator is transmitted. The emission window is formed with an anti-reflection film for suppressing surface reflection. The anti-reflection film has an angle dependence such that a lower limit of a reflectance is maintained in an incident angle range (0 to 20°) of the laser light at least corresponding to a scanning range of the laser light.

摘要： A beam irradiation device includes a photodetector which receives servo light and outputs a detection signal depending on a light receiving position of the servo light, and a signal processing section which obtains the light receiving position based on the detection signal. In the above arrangement, the signal processing section has an A/D conversion circuit which converts the detection signal into a digital signal, and an error signal adjusting circuit which converts an error component signal to be outputted from the photodetector when the photodetector is not irradiated by the servo light, into a signal within a processable range of the A/D conversion circuit, and supplies the converted signal to the A/D conversion circuit. A first digital signal derived from the detection signal is corrected with a second digital signal derived from the error component signal.

摘要： A laser radar according to an embodiment of the invention includes a beam irradiation head which emits a laser beam and a control circuit which controls the beam irradiation head to perform scan in a two-dimensional direction with the laser beam. In the laser radar, the beam irradiation head includes a laser beam source; a mirror to which the laser beam emitted from the laser beam source is incident; and a driving mechanism which rotates the mirror in first and second directions about a first rotating axis and a second rotating axis perpendicular to the first rotating axis respectively. The control circuit controls the rotation of the mirror in the first direction and the second direction such that a scan region of the laser beam becomes a rectangular shape.

摘要： The present invention provides smooth and adequate recording/reproducing on a recording medium employing a biodegradable material as a substrate material. The present invention relates to storing on a recording medium, information, structure, or the like indicating that a substrate is formed of a biodegradable material. When the present invention is applied to CD, CD-R, and CD-RW, identification information indicating a substrate formed of a biodegradable material is included in a free area of TOC data in a lead-in area shown in FIG. 4. An optical disc apparatus reads the identification information to identify whether or not a disc loaded into the apparatus has a substrate of a biodegradable material. When the loaded disc has a substrate of a biodegradable material, the optical disc apparatus: measures a temperature inside a drive; stops a recording/reproducing operation on the disc when the temperature approaches a glass transition temperature of a substrate material; and ejects the disc to outside of the apparatus.
