ABSTRACT:
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.
