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： It is an object of the present invention to improve a margin to meet good recording quality by conducting a realtime correction of a recording condition of a medium with different recording characteristics for inner and outer circumferences. To accomplish the object, control factors for power and a pulse width are independently detected and corrected using an mT pulse having a length of m′T as a pulse for power control and an nT pulse having a length of n′T as a pulse for pulse width control; more specifically, power correction for mT pulse and pulse width correction for nT pulse are conducted in realtime, wherein a recording pulse stream including the mT pulse and nT pulse is irradiated onto a medium by a recording laser beam as well as pits and spaces formed by irradiation of the recording pulse stream are reproduced by a reproducing laser beam to detect the effects of power and pulse width variations independently.
