摘要： An information recording apparatus is provided, which can control over the power of light beams emitted from a light source and various types of servo control with higher accuracy. A laser beam is emitted from a semiconductor laser to write information onto an optical disc. A detection signal indicative of the power of the laser beam output from a light-receiving device is sampled and held with a sample and hold circuit via an I-V converter at a timing delayed by the time corresponding to the delay time of the I-V converter. A tracking error generation circuit and a focus error generation circuit generate a tracking error signal and a focus error signal, respectively, on the basis of a detection signal having information about tracking error and focus error and output from a light-receiving device. Sample and hold circuits sample and hold the tracking error signal and the focus error signal at a timing delayed by the time corresponding to the delay time of each of the generation circuits, respectively. Power control, tracking servo, and focus servo are performed using each of the signals held by the sample and hold circuits, respectively.

摘要： An information recording reproduction apparatus includes a laser light source, a laser driving unit which supplies a laser driving signal to the laser light source to make it emit a laser light for recording and reproduction, a high frequency superimposing unit which superimposes a high frequency signal to a laser driving signal and a duty controlling unit which controls a duty ratio of the high frequency signal. The high frequency superimposing unit superimposes the high frequency signal on the laser driving signal driving the laser light source in order to prevent an effect due to a return light from an optical disc. The duty controlling unit controls the duty ratio of the high frequency signal so that generation of a higher harmonic component in the high frequency signal is decreased or so that the duty ratio becomes approximately 50%, for example.

The tilt servo-control apparatus includes: an optical pickup for irradiating an optical beam onto an optical disk and detecting a reflected light from the optical disk; a tilt-correction unit for correcting, using a correction amount, a tilt error due to aberration caused by a tilt angle formed between an optical axis of the optical beam and a normal line of the optical beam at an emitted position on the optical disk; an amplitude detecting unit for detecting a maximum amplitude and a minimum amplitude of a detected signal by the optical pickup within a period of one rotation of the optical disk; and a tilt-correction controlling unit for providing a control signal to control the correction amount used in the tilt-correction unit. The tilt-correction controlling unit includes a unit for applying variations to the control signal and adjusting the control signal so that a difference between the maximum amplitude and the minimum amplitude is minimized responsively to the variations.
