    摘要: There is provided an optical disc recording/reproducing apparatus which can reduce the chip size using the high-miniaturization process and can enhance the detection accuracy. A signal which is obtained by amplitude-adjusting a header region in a reproduced signal detected by an optical pickup (1) is digitized, and peak detection or bottom detection from the reproduced signal in each of a first section and a second section in the header region is performed by detection circuits (9) to (12), respectively. Then, amplitude data in the first section and the second section are obtained by subtracters (13) and (14) from the detected values in the respective detection circuits. A difference in amplitude between the first section and the second section in the header region is obtained by a subtracter (15) based on the amplitude data, and the amplitude difference is outputted as an off-track error signal. The respective detection circuits (9) to (12) perform detection operations in the first and second sections, and hold the detection operations in the sections other than the first and second sections.
