摘要： A light source device can attain a stable output of a harmonic even when there occurs a change in the ambient temperature or fluctuation in the output power. The light source device is provided with a semiconductor laser source (4), an optical waveguide-type QPM-SHG device (5) for generating a second harmonic from light emitted from the semiconductor laser source (4), a wavelength control means (7) for controlling a wavelength of light emitted from the semiconductor laser source (4), a means for slightly fluctuating wavelength (8) for changing a wavelength of light emitted from the semiconductor laser source (4) and a means for detecting a change in output light power of the optical waveguide-type QPM-SHG device (5) that occurs when a wavelength of light emitted from the semiconductor laser source (4) is changed. In this case, a wavelength of light emitted from the semiconductor laser source (4) is controlled to an optimum wavelength of the optical waveguide-type QPM-SHG device (5) based on a change in output light power of the optical waveguide-type QPM-SHG device (5) that occurs when a wavelength of light emitted from the semiconductor laser source (4) is changed.

摘要： Tilt of an optical storage medium is stably detected even when then the guide groove pitch is reduced and recording capacity is increased. On a disk with continuous grooves of a pitch Gp, part of tracks Gn−1 and Gn+1 adjacent to opposite sides of an n-th track Gn is eliminated, forming an area where the groove pitch is equivalent to 2·Gp. A push-pull signal from the area of groove pitch Gp and a push-pull signal from the area of groove pitch 2·Gp are differentiated to obtain a tilt error signal. Tilt can therefore be detected even when groove pitch Gp is reduced and storage capacity is increased, and a highly reliable data recording and reproducing apparatus can be provided at low cost.
