摘要： The present invention discloses an optical drive and a method for preprocessing a disc readout signal r k of an optical drive on the basis of a set of low-pass filters. The cutoff frequency f c of the filters wk, more particularly, can be set within the optical bandwidth, which improves the Viterbi detection performance in the case of high speed drive operations. Three types of filters are described, in which a Type I shaping filter performs best given a limited hardware cost for the bit detector. Compared to other more advanced noise- whitening techniques, it is only speed dependent and requires little prior knowledge of the channel and noise, thus cheap and easy to design. The invention can be applied in connection with optical disc drives, in particular when high frequency noises are dominant, for example, in the case of high speed operations.

摘要： The present invention provides a method and apparatus for robust tracking at narrow track-pitches on optical discs, enabling higher densities on Blu-ray Discs (5) as well as near-field discs. Increasing radial density results in loss of radial diffraction within the numerical aperture of the lens. Due to this loss in diffraction, current tracking methods, such as Push-Pull and Differential Phase Detection (DPD), will stop working. The invention provides a method and apparatus that relies on cross-correlating the central aperture (CA) signals of 3 optical spots (22, 24, 26) that are positioned such that there are a central spot (24) and spots (22, 26) positioned to the left (22) and right (26) of the central spot (4) . By using CA signals, the tangential diffraction is used, which is hardly affected by a track-pitch reduction.

摘要： A multi-stack optical data storage medium (20) for rewritable recording using a focused radiation beam (30), entering through an entrance face (25) is described. The medium (20) has a substrate (1a, 1b) and an L0 recording stack (2) and an L1 recording stack(3) both comprising a phase-change type L0 and L1 recording layer and the recording stacks are separated by a transparent spacer layer (4). The L0 recording stack (2) is present at a position closest to the entrance face (25) and has an optical transmission of TL0a and TL0c when the phase-change layer respectively is in the amorphous phase and in the crystalline phase. The medium (20) contains pre-recorded information modulated in at least one of: an embossed pregroove (21) in the substrate (1a, 1b), embossed pits in the substrate and recorded phase-change marks in at least one of the recording layers L0 and L1 (6, 11). The pre-recorded information contains a flag whether formatting of the L0 recording layer of the L0 recording stack (2) is needed depending on the transmission values TL0a and TL0c of the L0 recording stack (2). In this way it is achieved that the medium (20) has a good playability, recordability and random access behavior even when the L0 recording layer (2) has been partially recorded with information.

摘要： The present invention relates to optical system capable of reproducing information from an optical carrier by a main beam (C) for reading information as readable effects on the carrier, and a first (A) and a second (B) auxiliary beam. The optical system is adapted to direct the main beam (C) and the first (A) and second (B) auxiliary beam onto the carrier so that the main beam is positioned on a first track, and the first and second auxiliary beam are oppositely positioned on a second and a third track. The optical system can adjust a push pull (PP) radial error signal from the main beam by a function; f=f(A, B, C), where the function f is dependent upon adjacently positioned readable effects in the first, second and third track i.e. the local optical environment of the main beam. Therefore a filtering or "cleaning" of the push pull signal is performed depending on the local optical environment of the main beam.

摘要： The invention discloses an optical recording drive for recording data on an optical carrier such as an optical disk of the DVD or BD format. A radiation source is arranged to emit a write pulse train (80) for writing an optically detectable effect (90) i.e. a pit or mark. Photo detection means (10) detects a first reflected radiation beam pulse (R1) from a start time portion of the write pulse train (80) and generates a corresponding first signal (PS1) indicative of the power in the first pulse, the photo detection means (10) further detects a second reflected radiation pulse (R2) from an end time portion of the write pulse train (80) and generates a corresponding second signal (PS2) indicative of the power in the second pulse. By comparing (e.g. the heights of) the first signal (PS1) and the second signal (PS2), it is possible to get an indication of the received power in the optically detectable effect (90) as delivered by a power level (81; 82) in the write pulse train (80) continuously during writing and for a broad range of carrier rotation speeds.

摘要： The invention relates to a device and a method for determining a direction of movement (DOM) of a person carrying a portable acceleration sensor. The direction of movement (DOM) characterizes the motion direction of the person' s movements at certain points in time. By utilizing that the person's movement in directions other than the direction of movement (LAT) averages to zero over a given time interval, the forward direction of movement can be determined. The direction of movement (DOM) can be determined under the constraint of minimizing the displacements in a direction perpendicular to the direction of movement or by ensuring that the accumulated displacement perpendicular to the direction of movement (LAT) approximates (LAT) zero or is below a given threshold value.
