Data reproducing method using tilt adjustment and data reproducing apparatus for the same

摘要

In a method of obtaining a reproduction signal with good quality from a data recording medium, two actual signals are generated as first and second signals I₁ and I₂ from detection signals obtained from the data recording medium. A coefficient k which has linear correlation with a tilt is calculated based on the first and second signals I₁ and I₂. A reproduction signal in which influence of the tilt is eliminated, is reproduced by using the coefficient k and the first and second signals I₁ and I₂.
