An optical information processing apparatus is provided for at least either recording or reproducing information by projecting a converging light beam on a recording medium. The optical information processing apparatus includes a light detector for receiving the light beam, a neural network for inducing a tracking or focusing error signal from an output signal of the light detector, and a servo device for performing a tracking or focusing servo operation in accordance with the tracking or focusing error signal induced by the neural network.
