摘要： Playback durability of a writable optical disk is ensured. A method of controlling a playback condition includes continuously irradiating an optical disk with a laser beam having a power level lower than a mark formation level and detecting a change of a state of a signal caused by a return light from the optical disk, and setting a playback condition for the optical disk according to the change of the state of the signal. The playback durability of the optical disk can be ensured by adaptively controlling the playback condition as stated above.

摘要： Correction of recording power is appropriately performed to an optical disk. The recording power correction method includes a step of temporarily stopping data recording into an optical disk, reproducing a result of the relevant data recording, and specifying a detection pattern including a predetermined code in a reproduction signal; a step of detecting a signal state in the reproduction signal corresponding to the detection pattern; and a determination step of determining at least a correction direction of recording power in the data recording based on the detected signal state and a reference state specified from the detection pattern. Processing is performed on the basis of the detection pattern in this way, thereby the method can cope with even a recording and reproduction system for optical disk employing the PRML signal processing method.

摘要： The present invention enables a recording condition closer to an optimum to be obtained even for media unknown to a drive. The present invention provides a method that is especially effective for the case where it is applied to a code identification scheme, such as PRML in which code identification is performed on the basis of information on the amplitude of an RF signal. A condition for a recording pulse comprised of a top pulse, an intermediate pulse and a last pulse is configured in a predetermined order, that is, a reference condition is first determined by a test recording involving an examination of recording quality and changes in conditions for a power and a pulse width, then a condition for the last pulse is determined by a test recording using the reference condition, and subsequently a condition for the intermediate pulse is determined using the reference condition and the last pulse. A phase shift is corrected by a test recording using the recording pulse obtained by configuring the above conditions.

摘要： An optical information recording reproduction device is disclosed which finds the correlation between the ratio of the minimum pit amplitude to the maximum pit amplitude of an RF signal obtained from the light reflected by the pits recorded on an optical disk in a tracking servo mode and spherical aberration in advance, and stores it. In recoding information on the optical disk, the optical information recording reproduction device calculates the ratio of the minimum pit amplitude to the maximum pit amplitude of the RF signal, and compares the calculation to the stored correlation, and feeds back to an aberration correction optical system and a driving mechanical system to correct the aberration into an aplanatic state.

摘要： Several drives individually carry out recording and playback with a reference medium that serves as a reference for quality for various media, obtaining characteristic values. The characteristic values are multiplied by a predetermined coefficient to obtain thresholds, and the thresholds are stored in predetermined storage areas of the respective drives. When information is to be recorded on a medium, recording and playback are carried out with the medium under a plurality of recording conditions involving variation in power or pulse width, thereby obtaining characteristic values. Then, an approximated curve is obtained from the characteristic values. The quality of recording on the medium is tested based on an amount of margin that is determined according to positional relationship between the approximated curve and the threshold.

摘要： The invention provides a method effective in detecting a reproduction signal in real time correction in which correction is simultaneously performed with recording. In this method, a laser beam emitted from a laser diode 110 is divided into a plurality of beam spots by a diffraction grating 114. One of the plurality of beam spots is used as a beam spot for recording, and another beam spot is used as a beam spot for reproduction. Reflected light components obtained from these beam spots are independently detected by a detector 122. A period for which a recording laser beam is in an ON state is referred to as a gate signal, and a mask is put on an RF signal obtained from a beam spot for reproduction, thereby selectively detecting pits reproduced when the recording laser beam is in the ON state.

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.
