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： 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： A condition of a recording pulse comprising a top pulse and a following pulse is determined in a predetermined order. In some embodiments, an mT pulse condition is first determined by test recordings with various power and pulse conditions, involving an inspection of recording quality; then an m′T/(n−m)T ratio is determined by test recording under the mT pulse condition fixed; and finally an nT pulse is configured based on the ratio. A phase shift can be corrected by test recording with the nT pulse.

摘要： An optical information recording apparatus is suitable for detection of deviation between a strategy and a record pattern. Test record is performed on an optical recordable medium using a predetermined strategy. A binarization signal that is obtained by reproducing the test record result is counted. A pit length and a land length included in the binarization signal are specified using a histogram of the count result. A plurality of the reproduction patterns is searched and extracted from a record area based at least in part on the pit length and the land length. Deviation between a strategy and a record pattern formed by the test record is detected through comparison of the obtained reproduction patterns through the search.

摘要： It is an object of certain inventive aspects to provide a recording condition closer to an optimum even for a medium unknown to a drive, and more particularly, to provide means for obtaining a preferable recording condition even for a high-speed recording in which conducting a test recording is difficult. In order to accomplish the object, a power and a phase of a recording pulse are simultaneously corrected at predetermined timing, depending on a recording speed or a recording position such as an inner or outer circumference. For instance, a phase shift ΔPhase generated due to a continuing recording from an inner circumference to an outer circumference at ×2 speed is corrected simultaneously with a correction of a power shift at the timing when a recording speed is changed from ×2 to ×4. For the other recording speed, in the same manner as above, a power and a phase shift are simultaneously corrected at every time when a recording speed is changed.
