摘要： A detection system (100, 150) for qualitative or quantitative detection of a magnetic field property of a modulated magnetic field is described. The modulated magnetic field may e.g. stem from an adjacent electrical current (I adj ) or magnetic particles. The detection system (100, 150) comprises at least one magneto resistive sensor element (102), a current controller (104) for providing a sensing current (I sense ) flowing through the magnetic sensor element (102) and a controlling means (108). The controlling means (108) is adapted for deriving at a first frequency f 1 a temperature-related parameter of the at least one magneto resistive sensor. The controlling means (108) furthermore is adapted for deriving a qualitative or quantitative characteristic of the adjacent electrical current (I adj ) or magnetic particles, taking into account the derived temperature-related parameter. This second frequency (f 1 ) is different from the first frequency (f 1 }). The invention also relates to a corresponding method.

摘要： When a recording medium is recorded using a method for control of the crosstalk between tracks using control points any change in track pitch will directly result in other optimum values for those control points. If the recording medium is copied by a bit copier the control point values are also copied without modification but because of a shift of the data in adjacent tracks relative to each other the control point values are no longer the optimum values. This can be used to distinguish between an original and a copied recording medium. If the original recording medium is copied but the control point values are recalculated to be appropriate for the copied recording medium it can easily be detected that these recalculated values differ from the expected correct values, thus distinguishing a copied disc from the original disc

摘要： An optical reproducing apparatus in which reproduction of information is carried out by using an optical record carrier. In order to compensate a radial tilt between the surface of the record carrier and the objective lens, the objective lens is tilted. In the optical apparatus of the invention, the actuator of the radial displacement of the objective lens is used to also tilt the objective lens at the same time. A displacement of the objective lens in the radial direction by the actuator has a direct effect of tilting the objective lens. This is accomplished by a mechanical link between the radial displacement and the radial tilting. This has the advantage that there is no need for an extra tilt actuator to tilt the objective lens.

摘要： The invention relates to a method and a sensor device (100) for executing optical examinations in the investigation region (3) of a carrier (5). The sensor device (100) comprises an LED (22) that is operated with a constant current (Ip) and that emits an input light beam (Ll) towards the investigation region (3). An output light beam (L2) coming from the investigation region (3) is detected with a light detector (30), typically a camera, to provide intensity related raw measurement signals (Spix). The forward voltage (VF) across the LED (22) is sensed and used in a correction unit (50) to generate corrected measurement signals (Spix nrm). Thus the measurements can be made robust with respect to variations of the input light source (22).

摘要： When duplicating the record carrier the angle between the sync words S1 S2 can be preserved at the cost of a change in bit length, or the bit length can be preserved at the expense of changes in the angle between the sync words S1 S2. Consequently a playback device that checks for both changes in the angle between the sync words S1 S2, or between other marks, and for changes in bit length can detect an illegally duplicated record carrier with a high certainty.

摘要： Described is an invention relating to a bit-detection arrangement able to convert an analog signal (AS) into a digital signal (DS). The analog signal (AS) is fed to a quantizer (11). After the quantizer (11) the output signal S1 is fed to a phase detector PD1 (12). Also samples are taken of the output signal S1. The output signal PH2 of the phase detector PD1 (12) is dependent on the phase difference between the output signal S1 and the clock signal C2. If the frequency of the clock signal C2 is approximately equal to the frequency of the output signal S1 then the output signal PH2 of the phase detector PD1 (12) varies slowly. The analog to digital converter ADC (13) can therefore sample the output at a slow rate, dictated by the clock signal C1. The clock signal C1 is derived from C2 by dividing clock signal C2 by a factor n, whereby n is greater than one. To obtain the phase differences at clock periods of clock signal C2, the processed signal PrS of the analog to digital converter ADC (13) is interpolated. This can be done in different ways. A special embodiment comprises a digital phase locked loop DPLL (2) with discrete time oscillators. The obtained phase differences are used by the bit decision unit (3) to output the samples.
摘要翻译：描述了与能够将模拟信号（AS）转换成数字信号（DS）的比特检测装置有关的发明。模拟信号（AS）被馈送到量化器（11）。在量化器（11）之后，输出信号S1被馈送到相位检测器PD1（12）。也取出输出信号S1的样本。相位检测器PD1（12）的输出信号PH2取决于输出信号S1和时钟信号C2之间的相位差。如果时钟信号C2的频率近似等于输出信号S1的频率，则相位检测器PD1（12）的输出信号PH2变化缓慢。因此，模/数转换器ADC（13）可以以由时钟信号C1指示的慢速率对输出进行采样。时钟信号C1通过将时钟信号C2除以因子n从C2导出，由此n大于1。为了在时钟信号C2的时钟周期获得相位差，模数转换器ADC（13）的处理信号PrS被内插。这可以通过不同的方式完成。一个特殊的实施例包括具有离散时间振荡器的数字锁相环DPLL（2）。获得的相位差由比特判定单元（3）用于输出样本。

摘要： The invention relates to a device for reading and/or writing a disc-shaped information carrier (17), which comprises a support element (25) of a magnetizable material along its circumference. The device comprises an electromagnetic unit (27) for co-operation with the support element and a scanning unit (23) for reading and/or writing the information carrier. By co-operation between the electromagnetic unit and the support element, the information carrier can be rotated about an axis of rotation (73) and positioned with respect to the scanning unit (23) in five degrees of freedom, i.e. in all degrees of freedom except the rotational degree of freedom around the axis of rotation. According to the invention, the electromagnetic unit (27) comprises a single pair of rows (29, 31) of electromagnets (33, 35), which rows are arranged, along an X-axis perpendicular to the axis of rotation (73), on both sides of the information carrier. The electromagnetic unit (27) further comprises a first pair of electromagnets (37, 39) and a second pair of electromagnets (41, 43) which are diametrically arranged with respect to each other, viewed in a middle position of the information carrier (17) along the X-axis and viewed along a Y-axis perpendicular to the X-axis and the axis of rotation, the magnets of the first and the second pair being arranged on both sides of the information carrier, and the magnetic poles (69, 71) of the electromagnets of each pair being arranged at equal distances from the X-axis and, in each position of the information carrier along the X-axis, on one side of a magnetic point of application (M) of the support element. Thus, the electromagnetic unit has a comparatively simple construction and comprises a limited number of electromagnets, so that also the control unit, which is necessary to control the electromagnetic forces of the electromagnets, is simplified.
