摘要： PROBLEM TO BE SOLVED: To set an optimum power ratio with high precision in a short time concerning a binary pulse recording system by considering nonlinearity in a laser emission characteristic. SOLUTION: A signal is recorded with a recording laser, having binary power levels (Po, Pm, provided that Po>Pm) relative to an optical disk, concerning a recording power setting method. A power ratio k(=Po/Pm) is defined as a prescribed value, a test signal, which is obtained by changing recording power Po stepwise, is recorded in the optical disk, and then, the test signal recorded in the optical disk is reproduced. A β value, which indicates asymmetry of amplitude, is acquired from the reproduced signal, so as to calculate the change rate Δβ(=dβ/dPo) of the β value relative to the recording power Po. The value of the calculated change ratio Δβ in a target β value is compared with a target Δβ value. Based on the result, the power ratio k of the recording laser is corrected and set.

摘要： PROBLEM TO BE SOLVED: To shorten a time required for focus servo recovery processing caused by focus deviation during recording in an optical disk apparatus of a CLV(Constant Linear Velocity)system. SOLUTION: When focus deviation is caused and focus pull-in by retry cannot be performed, the number of rotation A at the radial position R is calculated.

Next, the number of rotation D at a pickup return position of other double speed is calculated. Next, rotation double speed at the time of pickup return is selected so as to reduce difference of the number of rotation to the minimum with all conditions of servo recovery after pickup return and access operation after servo recovery when pickup return is performed from focus deviation, considering relation of the number of rotation A, B, C, D.
