摘要： A focus servo control method for an optical disc device is provided which compensates for variations present on the disc while printing a label on a label surface of the disc. The label surface of the disc is radially divided into a plurality of areas arranged about the center of the disc, and a focus swing operation is performed for each of the radially divided areas to detect an RF signal. Respective center points of pulses in the detected RF signal are regarded as optimal focus points, and focus driving voltages corresponding respectively to the center points are detected and stored in association with the corresponding areas. When a label is printed on the label surface, feed-forward focus servo control is performed based on the stored focus driving voltages. Accordingly, feed-forward focus servo control can be performed while compensating for variations the disc, thereby improving the label printing operation and quality of the resulting label.

摘要： A reference pattern (300, 700) on the non-data side (or label side) (146) of an optical data storage disc (126) enables optical disc devices (102) to register a position of a laser (118, 308) to an absolute radial location on the disc's non-data side (146). The absolute radial location serves as a reference track to which that all radial positioning can be referenced.

摘要翻译：提供一种用于光盘装置的聚焦伺服控制方法，其在光盘的标签表面上打印标签时，补偿光盘上存在的变化。盘的标签表面被径向分成围绕盘的中心布置的多个区域，并且对于每个径向划分的区域执行聚焦摆动操作以检测RF信号。所检测的RF信号中的各个脉冲中心点被认为是最佳聚焦点，并且与相应的区域相关联地检测并存储对应于中心点的聚焦驱动电压。当标签印在标签表面上时，基于存储的聚焦驱动电压进行前馈聚焦伺服控制。因此，可以在补偿盘的变化的同时进行前馈聚焦伺服控制，从而提高标签打印操作和所得标签的质量。

摘要： Light-readable information-recording media are fabricated according to a method wherein the back of a production stamper is laser-scribed, diamond-scribed, etched, or marked by other means to produce an image. This production stamper is then used to form a substantially transparent substrate having information recorded on it by means of pits and lands. During the formation of the substrate, the image is transferred from the back of the stamper to the surface of the substrate. The resulting watermark may be visible under normal light conditions. Information-recording media bearing indelible watermarks according to the present invention are also disclosed.

摘要： An artifact (2) is used in the positioning of the read/write arm (4) during servo-writing (32) of a computer memory disk. A method for positioning the arm (4) using the artifact (2), and an apparatus incorporating the method is also included. The artifact (2), when applied to a moveable read/write arm 84), which traverses the surface (6) of a computer memory disk can be read without the presence of the housing, or through a permeable window in the housing of the disk, and which is read by an external laser beam (14; 84, 85) and thence processed by interference laser metrology techniques to produce an electrical signal which provides a representation of the displacement of the arm (4) from the center of the disk.
Winchester drives provided with one or more optical windows to view the artifact-containing arm are especially adaptable to use of this artifact (2), apparatus, and method of this invention.

摘要： The present invention relates to a data storage medium, such as a compact disk, combined with a data reader in which a stick-on label is applied to the data storage medium on the side opposite the data readable side. The stick-on label includes a user markable surface on one side and an adhesive coating on the other side which allows the label to be attached and removed from the data storage medium. The label comprises regions containing region numbers which correspond to information stored on the data storage medium. A user mark in a region indicates that the corresponding information is to be skipped when the data storage medium is played on the data reader. The printing which outlines the regions and provides the region numbers is light transparent. The data reader includes a scanner for scanning the regions as the data storage medium rotates. A timing ring with timing marks aids in the sampling of the user marks on the stick-on label.

摘要： An optical disc for use in optical memories has a memory data recording surface 16 overlain by a protective cover 14 to protect it from dust and contaminants. Position related data is recorded on the outer surface 24 of the cover 14 in a more gross and less densely packed format than is the memory data on the memory recording surface 16. By removing the positional data from the memory recording surface 16, (i) more space is made available on the memory recording surface and (ii) the positional data is more easily read by a moving position scanning beam.
