Abstract: The invention provides an optical disc device and a method of determining an optimal laser power for data recording by trial recording before recording actual user data even when there are fingerprints in the test track area for the trial recording. The BER (Byte Error Rate) is detected in each recorded sector. If the BER is less than a particular threshold value, the sector is taken as OK (good). Otherwise the sector is taken as NG (no good). While the peak power level is gradually changed or decreased from the power level at which half or more of the plural reproduced sectors are OK, a boundary peak power at which half or more of the sectors become NG is found. Based on the found boundary power, an amount of the optimal peak power is determined.

The optical disk includes a plurality of tracks each divided into a plurality of recording sectors. Each of the recording sectors includes a header region. The header region includes address information for identifying the position of the corresponding recording sector and address synchronous information for identifying the recording position of the address information for bit synchronization. The address information has been modulated using a run length limit code of a maximum inversion interval of Tmax bits (Tmax is a natural number), and the address synchronous information includes two patterns of which inversion interval is (Tmax″+3) bits or more, so that the reproduced signal of the address synchronous information is distinguished from the reproduced signal of other information.
