Optical information processing apparatus.

摘要

An optical information processing apparatus is so constructed that an optical head in the apparatus for recording and/or reproducing information by irradiating a light beam onto a recording medium is exchangeably attached to an apparatus main body, wherein a circuit (57) to compensate an offset of an electric signal which is output from the optical head is attached to the apparatus main body so that it can be exchanged together with the optical head, thereby making unnecessary an offset adjustment after optical head was exchanged.
