摘要： A controller (7) is disclosed for controlling the power supply to a laser (3) that is used in determining the motion of an object (8). The controller comprises a power source (2) that is arranged to supply power pulses (10, 11) to the laser (3) in response to a controller signal. The controller (7) controls the generation of pulses to those periods in which a reliable result can be obtained, by detecting the laser radiation that has interacted with pulses reflected from the object (8), in order to conserve power consumption. Further the power pulses (10, 11) comprise a heating component (9), which serves to stabilize the temperature of the laser (3) and therefore calibrate the laser (3) so that a known lasing wavelength is generated.

摘要： The waveform equalizer (6) for obtaining a corrected signal S' by performing a waveform equalization to a read signal S read out from an information carrier (1). The waveform equalizer (6) has a first filter (61) able to perform a filtering process to said read signal S, and an amplitude limiting means (62) able to obtain an amplitude limited read signal SLIM by limiting an amplitude level of said read signal S by a predetermined amplitude limitation value. A second filter (63) is provided which is able to perform a filtering process to said amplitude limited read signal SLIM. Further, an adder (64) is present which is able to add the signals obtained by performing the filtering process by each of said first (61) and second filters (63), able to generate an addition result as said corrected read signal S'. The signal frequency response of said waveform equalizer (6) to signals having an amplitude smaller than said predetermined amplitude limitation value, has a notch in a first frequency region from zero to a frequency at which the signal frequency response is at a maximum amplitude. The apparatus for reproducing information recorded on an information carrier (1), having the waveform equalizer (6) is able to read the information with a higher S/N ratio and a lower data jitter. As a result the information reproducing apparatus can be applied for a higher bit density and at the same time having a acceptable S/N ratio and data jitter.

摘要： A receiver is described for delivering a data sequence (ak) at a data rate 1/T from an analog signal (Sa), the receiver comprising: a) converting means (40) for generating a received sequence (rn) by sampling the analog signal (Sa) with a sample rate of 1/Ts, whereby the sample rate 1/Ts of the received sequence (rn) is controllable by a preset value (Pv); b) digital processing means (12) for delivering a processed sequence (yn) by processing the received sequence (rn); c) a first sample rate converter (13) for converting the processed sequence (yn) into an equivalent processed sequence (ye) at the data rate 1/T, whereby the data rate of the equivalent processed sequence (ye) is controllable by a control signal (Sc); d) an error generator (14) for delivering an error sequence (ek) from the equivalent processed sequence (ye); e) a control signal generating means (15) for generating the control signal (Sc) dependent on the error sequence (ek); f) a detector (16) for deriving the data sequence (ak) from the equivalent processed sequence (ye),whereby the ratio between the sample rates 1/T and 1/Ts is substantially constant. Conventional synchronous receivers which comprise a Sample Rate Converter have the disadvantage that the digital processing is performed within the control loop of the SRC. The delay resulting from the digital processing contributes to the overall delay of the loop, which can lead to instabilities, especially when high bandwidths are require. Therefore the receiver of the invention does the digital processing outside the control loop. To keep the advantage that the digital processing can be done at a fixed rate, the converting means (40) are controlled by a preset value for keeping the ratio T/Ts constant.

摘要： An optical disc medium 10 having a wobbled track groove 12 includes three wobble patterns including a flat wobble pattern, a positive pulse wobble pattern, and a negative pulse wobble pattern. In the flat wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is zero such that the track groove is flat. In the positive pulse wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is positive such that the track groove is wobbled in a first direction perpendicular to the lengthwise direction. Further, in the negative pulse wobble pattern, the amplitude of the wobble from the lengthwise direction of the track groove is negative such that the track groove is wobbled in a second direction opposite to the first direction. Then, three data values can be recorded using three distinctive wobble patterns.
