摘要： The present invention provides a single information recording and reproducing apparatus that is used to record data to multiple disks that are to be recorded on using different wavelengths. More specifically, the present invention provides an apparatus that accurately discriminates disk types while preventing disk damage and accidental recording of data during the disk type discrimination operation. The disk type is determined using the intensity of light reflected from the disk. Information is encoded using an encoder corresponding to the disk type. The resulting signal is used to drive a laser corresponding to the disk type, and information is recorded.

摘要： An objective of the present invention is to enhance reliability of recorded data by preventing deterioration of OPC (Optimum Power Calibration) accuracy due to an influence of inter-layer interference in an optical disk device capable of writing in a multilayer optical disk. Aiming at the objective, a relationship between asymmetry and a signal modulation depth, which are measured by use of a standard driver is referred, and thereby an offset caused by a device, a disk, a writing state of another layer and the like is compensated. Thus, OPC is executed.

摘要： In a comparator circuit comprised of a feedback amplifier and a differential amplifier AMP1, the feedback amplifier includes input transistors Tr1 to Tr4. Gates of the transistors Tr1 and Tr2 are respectively inputted with first and second inverted inputs, and gates of the transistors Tr3 and Tr4 are inputted with first and second non-inverted inputs. First ends of current paths of the transistors Tr3 and Tr4 are connected in common, and ends of current paths of transistors Tr1 and Tr2 are connected in common. Second ends of the current paths of the transistors Tr1 to Tr4 are connected in common to a constant current source. The first and second inverted inputs are supplied with a reference voltage, and the first and second non-inverted inputs are respectively supplied with the non-inverted and inverted outputs of the differential amplifier AMP1. A signal from a connection point common to the first ends of the current paths of the transistors Tr3 and Tr4 is supplied as a feedback output to the differential amplifier AMP1 to control operation of the differential amplifier AMP1. The timing when feedback is performed to stabilize the operating point of the differential amplifier AMP1 is the timing when the non-inverted and inverted outputs of the differential amplifier AMP1 have a small potential difference therebetween or are substantially equal to each other.
