摘要： An optical scanning device (3) for scanning a multiple of types of optical recording media. The optical scanning device is provided with a filtering means (301) that is arranged and configured such that when scanning an optical recording medium (15) having plurality of information layers (L0, L1) radiation reflected by another information layer than the information layer being scanned is not reaching the radiation detector (38), while the filtering means is substantially not affecting the radiation towards the radiation detector when another type of recording media is scanned. Improved data signal reproduction and tracking servo signals are obtained.

摘要： An optical pick-up unit is suitable for scanning a first type of record carrier having a first information density and at least a second type of record carrier, the second type of record carrier having a second information density different from the first information density. The optical pick-up unit comprises a first radiation source (16, 86) for emitting a first diverging radiation beam (24) for scanning the first type of record carrier, and at least a second radiation source (48, 96) for emitting a second radiation beam (50) for scanning the second type of record carrier. The optical pick-up unit also comprises a first beam splitter (58, 93, 104) for combining the first radiation beam and the second radiation beam on a common optical path. The first beam splitter is a plane-parallel plate-type beam splitter. A correcting element (20, 22, 72) for astigmatism and coma correction is arranged between the first radiation source and the first beam splitter.

摘要： The present invention relates to a method of reading out information from a multiple layer optical recording medium (10) by an optical readout device (12), the method comprising the steps of: focusing a central light beam (14) and two satellite light beams (16, 18) onto a first recording layer (20) of the optical recording medium, projecting reflection beams (22, 24)of at least part of the satellite light beams on two split detectors (26, 28), thereby creating satellite spots (116, 118), each split detector being associated with one of the satellite light beams, the reflected light interfering with light reflected by a second recording layer (21), and processing the signals from the split detectors for providing a tracking error signal, wherein the influence of a central part (29) of the reflection beams on the tracking error signal is removed and/or modified, thereby reducing a negative influence of this central part on the quality of the tracking error signal. The present invention further relates to an optical readout device (12) and to a grating (3Oe) for use in an optical readout device (12).
