Abstract: An optical information recording/reproducing apparatus for optically recording/reproducing information by irradiating a track on a recording medium with a light comprises: a detecting circuit, a tracking error signal producing circuit, and a tracking control circuit. The detecting circuit selectively detects a circular area having a diameter smaller than a diameter of a light beam reflected from the recording medium and obtains an output signal corresponding to the detected circular area. The tracking error signal producing circuit produces, from the output signal of the detecting circuit, a tracking error signal indicating a shift in a position of a light beam irradiated on the recording medium in a track width direction. The tracking control circuit controls an irradiation position of a light beam irradiated on the recording medium in the track width direction based on the tracking error signal.

Abstract: An optical disk apparatus comprising a light source for emitting a light beam, an optical system for focusing the light beam to form a beam spot on the optical disk, a tracking unit for detecting the light reflected from the optical disk to generate a tracking error signal from the light by a differential phase detection method, and move the beam spot in accordance with the tracking error signal, and an information-readout section for reading out information from the optical disk. To achieve readout compatibility between a high-definition DVD and a DVD-ROM, a predetermined delay is given relatively to first and second signals obtained from two pairs of regions arranged in two crossing diagonals of a quadrant photodetector, thereby shifting the beam spot from the centerline of the pit stream in the radial direction of a DVD-ROM, in order to read out information from the DVD-ROM.
