Abstract
According to an embodiment, a signal processing apparatus includes a first signal processor, a second signal processor and a third signal processor. The first signal processor suppresses an offset component remaining in a reproduction signal read from an optical recording medium to obtain a first signal. The second signal processor suppresses a nonlinear distortion component remaining in the first signal to obtain a second signal. The third signal processor suppresses a correlation noise component remaining in the second signal to obtain a third signal.
