摘要： The invention provides an effective method for improving accuracy of recording, tracking, and reproduction in a real-time correction in which correction is performed simultaneously with recording. A beam spot for recording, beam spots for reproduction, and beam spots for tracking are formed by branching a laser beam outputted from a laser diode by using a diffraction grating. In this manner, by providing the beam spots for recording, reproduction, and tracking independently, signals which are subjected to less reproduction degradation are obtained while maintaining tracking accuracy.

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： Novel evaluation indexes are introduced to allow both a total evaluation of data recording and an evaluation of individual detection patterns. A data recording evaluation method includes a step of reproducing a result of data recording performed on an optical disk and identifying a predetermined detection pattern in a reproduction signal, a step of detecting a signal state of the reproduction signal associated with the predetermined detection pattern, and a first calculation step for calculating a first evaluation index value based on the detected signal state and a reference state identified from the predetermined detection pattern. When there is a plurality of predetermined detection patterns as described above, a second calculation step is further provided for calculating a second recording state evaluation index value using the first evaluation index value calculated from each of the predetermined detection patterns. Data recording can be properly evaluated using the first and second recording state evaluation index values.
