Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser equipped with a semiconductor laser element, in which the output current characteristic of a laser output to a monitoring PD is linear in both the low-output region and the high-output region, and in the transition region to the high-output region from the low-output region. SOLUTION: This laser coupler comprise a PDIC 12, the semiconductor laser element 14, and a Pin PD 16 which are integrated on the PDIC and the monitoring PD 18 which is installed on the PDIC at the front of the emission direction of the semiconductor laser element, and which detects the optical output of a laser beam of the semiconductor laser element for outputting an output control signal. The planar pattern of the light-receiving plane of the monitoring PD is formed into a trapezoidal shape, which is demarcated by two side faces forming the same angle as an emission angle θpall2 of the laser beam at high output. An emission angle (θpall) is wide at low output, and it becomes narrow at high output. The monitoring PD having the light- receiving planar pattern into the trapezoidal shape cannot receive a part of the laser beam of the semiconductor laser element. Consequently, coupling (F1 ) of the semiconductor laser element to the monitoring PD becomes small, and since coupling F2 is constant, adjustment ImL=1 is made.

Abstract: PROBLEM TO BE SOLVED: To perform dubbing without the aid of a computer. SOLUTION: When the input operation of a dubbing key 54 (54 or 55) is discriminated to be detected, whether recording media of both of a disk and a memory card are loaded into a disk drive assembly or not is discriminated and when both media are discriminated to be loaded, whether a command supplied from a host computer is currently executed or not is discriminated (S001 to S003). When the command is discriminated to be not executed, the inputted dubbing key is identified and when the dubbing key 54 is discriminated to be inputted, the data is read out of the disk and the data dubbing to the memory card is executed (S004, S005). When the dubbing key 55 is discriminated to be inputted, whether the loaded disk is a recordable disk, such as, for example, a CD-R/CD-RW or not is discriminated and when the disk is discriminated to be recordable, the data dubbing from the memory card 40 to the disk 90 is executed (S006, S007).

Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly and easily discriminate the kind of a loaded disk by utilizing the difference in the signal planes in the thickness direction of the disk and discriminating whether the loaded disk is a first kind or second kind by using reflected light information. SOLUTION: When the disk D is inserted, a DVD pickup 1b is set in a DVD pickup mode to be used. As the discrimination operation, an objective lens 2b for DVD is forcibly elevated or lowered within a focus search stroke range, and it is instructed to start the output of a focus search drive signal. A system controller 30 detects the discrimination signal DD supplied from a discrimination signal forming circuit 27 and measures the period between two pulses while executing the movement of the objective lens 2b for DVD within the prescribed region. A measured value and a reference value are then compared and the disk D is judged to be a CD when the measured value is longer.

Abstract: PROBLEM TO BE SOLVED: To make stably controllable the write power during recording even in a pulse-train recording. SOLUTION: After writing starts, S/H 204 samples the output signal WRF' of an LPF 203 at specific time intervals corresponding to a specific pulse width part of recording data RD to find the pit level LVP. The signal WRF' has a variation part, corresponding to the multi-pulse train of a write RF signal WRF, smoothed. A controller 124 corrects the level of a target level signal STA supplied to an APC circuit 202 so that the pit level LVP becomes equal to an optimum pit level LVPr found before the writing. The pit level LVP is obtained after the variation part of the write RF signal WRF is smoothed by the LPF 203, so the pit level LVP can stably be obtained without being affected by the multi-pulse train and the write power can stably be controlled.
