摘要： An optical information recording apparatus corrects a recording condition for an optical medium having a difference in recording property between the inner and outer peripheries in real time. The optical information recording apparatus obtains an RF signal by using a playback sub beam and retrieves a portion of the RF signal corresponding to a constant output zone of a recording pulse using a gate signal. An average value of the retrieved signal is computed so as to set a reference position in real time. A difference between the top peak value of the retrieved signal and the average value and a difference between the bottom peak value of the retrieved signal and the average value are computed so as to obtain a β value in real time from the on-and-off RF signal affected by the recording pulse that turns on and off.

摘要： Provided are an optical information recording device, an optical information recording method, and an optical information recording medium which provide an appropriate recording characteristic even when a disturbance occurs during information recording. A drive forms record marks and spaces by irradiating blue-purple laser light to an optical disk, for which an organic dye exhibiting a predetermined absorption factor with respect to light having a wavelength of at or near 405 nm is used, and thus records information. For recording of information, the power of the blue-purple laser light is controlled using writing power used for forming record marks, space formation power used for forming spaces that may be higher than read power used for reproducing information recorded in an optical information recording medium, and bias power higher than read power.

摘要： Processing along one circular path is performed by irradiating a laser beam to a ceramic green sheet attached on an outer peripheral surface of a rotating drum, and the processing path is changed by moving at least one of the rotating drum and a beam irradiated position through a predetermined distance in the direction of drum centerline each time the processing on one circular path is completed. If the laser beam is intermittently irradiated to the ceramic green sheet, a matrix of through holes or concave portions can be easily formed in the ceramic green sheet.

摘要： A technique for measuring displacement involves passing parallel laser light from a laser light source through a first diffraction grating to a semi-transparent semi-reflective mirror. A portion of the laser light is reflected as first reversed light, which passes through the first diffraction grating. The remainder of the parallel laser light proceeds to a total reflection mirror and is reflected as second reversed light that passes through the semi-transparent semi-reflective mirror and the first diffraction grating. The amount of refracted light of a predetermined order that is of the first and second reversed light and that results from the first diffraction grating is detected by a first optical sensor, and the amount of displacement is obtained from the interference band or a signal thereof corresponding to the amount of relative motion in the axial direction of the total reflection mirror with respect to the semi-transparent semi-reflective mirror.

摘要： There is proposed an optical disk recording method that can prevent degradation of recording quality due to occurrence of thermal interference, and an optical disk recording reproduction device used in this recording method. The recording method has a step of executing a test record on an output proofing area of the optical disk 150 while a spot diameter of the recording laser beam is varied, and deriving the relationship between the spot diameter and a characteristic value representing recording quality, a step of deriving a permissible range of a variation amount of the spot diameter on the basis of the derived relationship between the spot diameter and the characteristic value representing the recording quality; a step of irradiating a record region of the optical disk with the recording laser beam to detect spherical aberration while executing recording; and a step of executing aberration correction, in case the spherical aberration occurs, such that a variation amount of the spot diameter falls into the derived permissible range.
