摘要： A record carrier is described for recording information by writing marks in a track. The record carrier has a pregroove (14) indicating the position of the track. The pregroove exhibits a wobble and in addition thereto a pregroove modulation (13) constituted by variations of a physical parameter related to the shape of the pregroove, e.g. width or depth. The marks are detectable during scanning the track via a beam of radiation by a first type of variations of the radiation, e.g. by changes of reflected radiation. The pregroove modulation (13) is also detectable by variations of said first type, whereas the wobble is detectable during said scanning by a second type of variations of the radiation.

摘要： A device has a head for recording information by writing marks in a track on a record carrier via a beam of radiation. The radiation is controlled to write the marks (40) having a main mark intensity (44) and a mark length within a predefined range of mark lengths. Further secondary marks (41) are recorded in the same part of the track. The secondary marks have a secondary mark intensity (43) that is substantially different from the main mark intensity and a length substantially longer than mark lengths in the predefined range. Furthermore a record carrier, method of recording and a read device are described.

摘要： A record carrier comprises three layers that react with each other when irradiated to form a mark on the record carrier. The three layers are separated by a two separating layers that prevent direct contact of the three layers thus providing stability to the record carrier. By irradiating one or both separating layers a region of those separating layers is destroyed or altered whereby an opening is created and the reaction of the layers adjacent to the separating layer is no longer prevented in that region and a mark can be formed. Since either one or two reactions can take place if one or both separating layers are destroyed or altered multiple reflection levels for a mark can be obtained, thus enabling multilevel recording where a single mark can represent more information compared to the situation where only two reflection levels can be obtained. The size of the resulting opening determines the size of the mark and can thus be used to create a very small mark allowing high density recordings.
摘要翻译：记录载体包括三层，当被照射时彼此反应以在记录载体上形成标记。这三层由两个隔离层隔开，防止三层的直接接触，从而为记录载体提供稳定性。通过照射一个或两个分离层，这些分离层的区域被破坏或改变，由此产生开口，并且在该区域中不再防止与分离层相邻的层的反应，并且可以形成标记。由于如果一个或两个分离层被破坏或改变，则可以获得一个或两个反应的一个或两个反应，因此可以获得标记的多个反射水平，从而能够进行多级记录，其中单个标记可以表示更多信息，与仅两个反射级别可以获得。所得到的开口的尺寸决定了标记的尺寸，因此可以用于产生允许高密度记录的非常小的标记。

摘要： An optical data storage medium is described. It comprises at least a substrate, having a surface with data stored in pits that are embossed into the substrate and in spaces separating the pits, a reflective layer covering the surface and having an intrinsic optical reflectivity R at a wavelenght λ, a transparent cover stack formed on the reflective layer, the pattern of pits being readable through the cover stack by means of the focused radiation beam having the wavelength λ.

摘要： An optical disc (3) for storing data is provided with a label material layer (8) on a laser entry side of the disc (3). The label material layer (8) does not impede reading data from or writing data onto the disc (3). Reflection or absorption of light in the visual spectrum by the label material in the label material layer (8) is affectable by illuminating the label material according to a label pattern. Changing the reflection or absorption results in a local change of color. The contrast that is herewith applied to the label material layer (8) can be used for creating visual information, such as text or images for forming a label. Furthermore a device (52) is provided for applying a label to the laser entry side of an optical disc (3). The device (52) comprises means for producing a laser beam (21) for illuminating the label material layer (8) according to a label pattern.
