ABSTRACT:
An optical pickup assembly for a multitrack optical disk reader includes a multi-element photodetector onto which a plurality of reflected track images are projected. Circuitry is provided for detecting a magnification error, and for generating a magnification error correction signal to correct or compensate for the magnification error. Circuitry is also provided for correcting for cross-talk components in the output signals of the multi-element photodetector responsive to the detected magnification error.
