    摘要： An optical data carrier disk reader is adapted for detecting a slope of a wall in a data track of an optical disk. An optical disk has pits (811, 812), having walls with at least two different steepnesses, in its data track. The steepness represents information written on the optical disk. A method for making an optical disk stamper (8) comprising exposing portions of a photo-sensitive layer to electro-magnetic radiation is also described. By controlling the variation of the focal point during exposure, the inclination of the walls between the bump (811, 812) or pit forming portions and the “land” forming portions of the surface of the optical disk stamper (8) can be controlled.

    摘要： A multilayer record carrier is for recording information by writing marks representing addressable blocks in a track. Each recording layer has a pre-formed recording control pattern for indicating the track, the pattern comprising physical addresses (59) that indicate the physical position of the physical address with respect to a starting point of the track. The predefined number of bits of the physical address indicates the physical position with respect to a starting point of the track. At least one address bit of the predefined number of address bits of the physical address is allocated as a layer address bit (60) that has a value indicating the recording layer. A recording device has a layer unit (34) for detecting a recording layer in dependence of the layer address bit.

    摘要： A dual-stack optical data storage medium (10) for write-once recording using a focused radiation beam (9) having a wavelength λ of approximately 655 nm is described. The radiation beam enters through an entrance face (8) of the medium (10) during recording. The medium comprises at least one substrate (1, 7) with present on a side thereof: a first recording stack (6), named L0, comprising a write-once type L0 recording layer, said first recording stack L0 having an optical reflection value RL0 and an optical transmission value TL0, a second recording stack (3), named L1, comprising a write-once type L1 recording layer, said second recording stack L1 having an effective optical reflection value RL1eff. The first recording stack (6) is present at a position closer to the entrance face (8) than the second recording stack. (3). A transparent spacer layer (4) is sandwiched between the recording stacks (3, 6). The reflection values RL0 and RL1eff are within the following ranges: 0.12≦RL0≦0.18 and 0.12≦RL1eff≦0.18 by which an improved sensitivity of the dual stack medium is achieved.

    摘要： A record carrier is for recording information by writing marks in a track. The record carrier has at least a first recording layer (40) and a second recording layer (41). Each layer has a pregroove (14) indicating the position of the track and exhibiting a wobble modulated for representing physical address information. In addition the pregroove has a pregroove modulation (13) consituted by variations of a physical parameter related to the shape of the pregroove for encoding axiliary control information. In a scanning device the pregroove modulation is detected in the main detector signal by variations of the reflected radiation.

    摘要： A record carrier is for recording information by writing marks in a track on a recording layer. The shortest mark used for recording the information has a length of a predefined minimum number d of channel bit lengths. The record carrier (11) has a pregroove that is modulated by a carrier pattern containing long marks (18,19) that provides a focus area (12) at a predefined location on the recording layer. The long marks have lengths of at least two times the length of the shortest mark for being substantially longer than the effective diameter of the scanning spot. A scanning device locates the focus area and determines the best focus offset by detecting the maximum read signal amplitude while scanning the carrier pattern.

    摘要： The present invention relates to a recording apparatus, record carrier and method of recording data on at least two layers of a recording medium by using a radiation power, wherein individual recording speeds are determined for respective ones of the at least two layers at different values of the radiation power. A recording speed to be used for recording on an individual one of the at least two recording layers is selected based on a maximum radiation power specified for the recording operation, and the speed of the recording operation is controlled individually for each of the at least two layers based on the selected recording speed. The determination of the individual recording speeds at different radiation power values may be written or embossed on the record carrier. Furthermore, a recording sequence used for recording on the recording layers can be set based on the sensitivities and thus recording speeds. Thereby, total recording time can be minimized for multi-layer recording media.
