ABSTRACT:
When recording is carried out in a DVD-RAM, if at least one address mark could have been detected at the header section, after a test light emission for a laser power control is carried out at a GAP section, normal recording is carried out from GUARD1. Herein, if the delay time in the reproduced data would have increased, and if the head of the GAP section has been passed by at the timing when the AM4 is detected in a period during judging whether the fourth AM has been detected or not, it would not be possible to carry out a test light emission normally at the GAP section. In an optical disc recording device of the present invention, when any of the first to third address marks could have been detected, a test light emission is carried out at the GAP section as conventional, and normal recording is carried out from GUARD1 with controlling the laser powers on the basis of that result. When only AM4 could have been detected, the test light emission is not carried out and normal recording from GUARD1 is carried out.
