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).

摘要： A switchable diaphragm (9) and a device for beam deflection (10) are placed in the servo branch of an optical drive, in a path of light beams of different diffraction orders. This permits redirection of light beam orders towards a detection means (8) on an individual basis and selection of light orders at a detection means (8) depending on requirements. The number of detectors in the device detection means (8) can thus be reduced, thereby also reducing additional components associated with those detectors and saving on cost and complexity. With such device functionality, new methods for measuring beam landing and spherical aberration are developed.

摘要： Apparatus and method for measuring the depth of data record layers of an optical storage disc having a cover layer of thickness d, an entrance surface (S), and, for example, a first data layer (L0), a second data layer (L1) and a third data layer (L2). The optical apparatus comprises a spherical aberration compensator (SA), and an objective lens (OL) mounted in an actuator (AC), the actuator (AC) receiving a current I and being arranged and configured to move the objective lens (OL) in the z (axial) axis relative to the optical storage disc. Light incident on the objective lens (OL) is converged into a cone-like beam such that it is focussed on one of the data layers (D1). A control signal is used to keep the scanning spot focussed on the data layer (L1). This control signal is the focus error signal (FES) and is provided by the actuator drive (AC). In order to provide the spherical aberration compensator (SA) with right control signal, the depth of each data layer must be measured and means are provided for measuring the depth of the data layer(s) of a single- or multi-layer disc, and this achieved by using the distance between zero-crossings of the focus error signal (FES).

摘要： In the described method of producing a plurality of bodies bearing equal imprints of a stamp as optical structures, a stamp (13) is initially produced, by attaching particles (14) to a surface (15) of an auxiliary body (16); than, the stamp (13) is used to produce an imprint (11) on a plurality of bodies (10). Optical structures can be irradiated, producing on a screen a speckle pattern indicative of a key. It is substantially impossible to clone a given optical structure with current technological means. Optical structures represent physical One-Way Functions, easy to compute in the forward sense but unfeasible to reverse. Thus, they can be used to build an access/copy protection system of user information contained in an information carrier associated with the body 10. The reproducibility of the optical structures makes this method suitable for optical disks.
摘要翻译：在所述制造多个具有作为光学结构的印模的印记的物体的方法中，通过将颗粒（14）附着在辅助体（16）的表面（15）上，最初产生印模（13）。使用印模（13）在多个主体（10）上产生印记（11）。可以照射光学结构，在屏幕上产生指示关键的斑点图案。以目前的技术手段克隆给定的光学结构是完全不可能的。光学结构表示物理单向函数，容易在正向方面计算，但不可逆转。因此，它们可以用于构建包含在与主体10相关联的信息载体中的用户信息的访问/复制保护系统。光学结构的再现性使得该方法适用于光盘。
