ABSTRACT:
It is an object of the present invention to provide a method for absorbing individual variance between optical disc devices or optical discs, and for determining the optimal servo adjustment position even with optical discs in which no convex/concave pit string is present. When mounting a disc, servo position adjustment is performed in at least two stages: first servo position adjustment and second servo position adjustment. Also, the second servo position adjustment is performed by recording a predetermined signal after the first servo position adjustment and reproducing the track where the predetermined signal was recorded.
