摘要： A recording device records marks in a track on a record carrier via a beam of radiation. The device has a focus servo unit for focusing the beam to a scanning spot on the track. A focus adjustment unit adjusts the focus servo unit in dependence on a focus offset, and determines the focus offset during recording as follows. The recording process (112) is suspended, and the scanning spot is moved (113) to a recorded part of the track near the location of the track to be recorded. Previously recorded marks are read using a multitude of focus offset settings (114) and subsequently a quality parameter of the scanning signal is measured (115). Finally the focus offset is calculated (117) in dependence on said measuring and focus offset settings. A record carrier may have a focus adjustment indicator indicating a focus adjustment setting to be applied during determining the focus offset.

摘要： This invention relates to a method for recording information on a multi layer record carrier. The information is recorded on the record carrier according to special filling patterns, such that the record carrier is compatible with the DVD-ROM standard while the time required for closing a session and/or finalizing the disc is reduced. The information is substantially evenly distributed over the layers in blocks of a predefined amount of storage space. The size of these blocks may be flexible and set by the method or read from the record carrier.
摘要翻译：本发明涉及一种在多层记录载体上记录信息的方法。信息根据特殊的填充模式被记录在记录载体上，使得记录载体与DVD-ROM标准兼容，同时减少了关闭会话和/或完成光盘所需的时间。信息基本均匀地分布在预定量的存储空间的块中的层上。这些块的大小可以是灵活的，通过该方法设置或从记录载体读取。

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： 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.
