摘要： The present invention relates to a method of selecting a range of gain values (2000) of a gain-bandwidth limited photo-detector circuit (45) for reading data from a record carrier (104). The method comprises: a) finding a first read power by setting a maximum allowable gain value (gmaχ), the first read power being a minimum read power value at which data is readable from the rotating record carrier at a first speed; and b) finding a second read power and a second gain value, by increasing the first read power value and decreasing the maximum allowable gain value. The second read power being the minimum read power value at which data is readable from the rotating record carrier at a second speed. The method is useful for all kinds of photo-detector circuits in optimizing gain values and achieving optimum performance with the optimum number of gain values.

摘要： A method of reducing power dissipation in a variable-gain photo-detector circuit is described. The variable-gain photo-detector circuit has an output to output a main spot signal and at least one side spot signal. The main spot (M) and the side spot (Si or S2) are formed by separating a light beam into a main beam and at least one side beam and focusing the main beam on the main spot (M) and the side beam on at least one side spot (Si or S2) on an optical record carrier The method processes the main spot signal with a first averaging circuit having a first cut-off frequency. The side spot signal is processed with a second averaging circuit having a second cut-off frequency. The second cut-off frequency is lower than the first cut-off frequency. The above technique reduces power dissipation in the variable-gain photo-detector circuit and is useful for all optical devices.

摘要： A recording device records marks in a track on a record carrier via a beam of radiation. The record carrier has a preformed track pattern such as a wobbled pregroove having prepits for encoding record carrier information. The device has a head for generating a scanning spot on the track and a front-end unit coupled to the head for generating detector signals based on radiation reflected from the track, the detector signals including a left subdetector signal and a right sub-detector signal. The device has a demodulation unit for retrieving the record carrier information from the detector signals, which includes a radial modulation signal circuit (34). The circuit generates a radial modulation signal (66) based on a difference signal of the sub-detector signals (61,62) normalized by a sum signal of the sub detector signals, and generates the sum signal by adding a correction amount. Thereby overcompensation due to normalization is reduced.

摘要： In summary, the present invention provides an efficient method of calibrating power for writing visible labels on an optical record medium. If the writing power is too low, the label will have a low contrast, while the image might even disappear after some time. If the writing power is too high, ablation might occur which means that the layer comes off forming blisters or flakes. The present invention solves this problem by providing a calibration method wherein a test pattern is recorded on an optical record medium with different power of the beam of light, the patterns recorded are read back and a reference power value is obtained from the patterns read back using a predetermined criterion. This reference power value obtained is used to calibrate the power needed for writing visible labels on the label side of an optical record medium.
摘要翻译：总之，本发明提供了一种校准用于在光学记录介质上写入可见标签的功率的有效方法。如果写入能力太低，标签的对比度就会降低，而图像甚至会在一段时间后消失。如果写入能力太高，则会发生消融，这意味着该层脱落形成水疱或薄片。本发明通过提供一种校准方法来解决这个问题，其中测试图案被记录在具有不同光束功率的光学记录介质上，记录的图案被读回，并且从使用回读的图案获得参考功率值预定标准。所获得的参考功率值用于校准在光学记录介质的标签侧上写入可见标签所需的功率。

摘要： In summary, the present invention provides a method for estimating maximum available write power of an optical storage drive. Optical drives have a certain guaranteed maximum power corresponding to the largest emission angles and worst case electrical parameters of the laser, but many drives could produce more if needed because they are not worst case. The extra power that is available from the lasers that is not worst case is wasted. By identifying drives with lasers that have favorable parameters, the maximum available write power of a drive becomes larger. The present invention solves this problem by providing an estimation method wherein a beam of laser light is generated having a power level (P), a first parameter of the laser light source and a second parameter of the beam of laser light that is generated are measured and used to estimate the maximum available write power.
摘要翻译：总之，本发明提供一种用于估计光存储驱动器的最大可用写入功率的方法。光驱具有对应于激光器的最大发射角度和最差情况的电气参数的一定的保证最大功率，但是如果需要，许多驱动器可以产生更多的驱动器，因为它们不是最坏的情况。激光器提供的额外功率不是最坏的情况是浪费的。通过识别具有有利参数的激光器的驱动器，驱动器的最大可用写入功率变大。本发明通过提供一种估计方法来解决这个问题，其中产生具有功率电平（P），激光光源的第一参数和产生的激光束的第二参数的激光束并用于估计最大可用写入功率。
