  • Patent number: 8000213
    Abstract: 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.

A second comparator (112b) compares a second voltage signal to a predetermined threshold to output a second binary signal corresponding to a comparison result. A first digital sampling section (113a) samples the first binary signal output by the first comparator 112a to generate a first sampling signal. A second digital sampling section (113b) samples the second binary signal output by the second comparator (112b) to generate a second sampling signal. A phase difference detector circuit (114) detects a phase difference between the first sampling signal generated by the first digital sampling section (113a) and the second sampling signal generated by the second digital sampling section (113b).
