| A method of forming an optical disc, and an optical disc formed, so as to facilitate identifying unauthorized copies of the disc by using a defined procedure for reading the disc. The method comprises the steps of encoding digital data, comprised of a series of Os and 1s, in the disc by forming a series of spaced pits along a track, so that the track comprises a series of pits and lands, and wherein, when said defined procedure is used to read the disc, each of said pits and lands is read as either a 0 or a 1. The method comprises the further step of forming at least one fuzzy area on the track so that when the defined procedure is used to read the disc, the fuzzy area is sometimes read as 0 and sometimes read as 1. With a preferred procedure, the pits reflect a given light beam at a first intensity, the lands reflect the given light at a second intensity, and the fuzzy area reflects the given light at a third intensity substantially midway between the first and second intensities. | ||||||

| 87 | OPTICAL RECORD CARRIER AND SCANNING DEVICE | PCT/EP2000/011825 | 2000-11-27 | WO01045096A1 | 2001-06-21 | |
| An optical record carrier is described comprising a track for carrying data encoded in optical marks. A parameter of the track has a periodic variation for generating a varying signal when scanning the track, for example a variation of the center of a pre-groove usually called wobble. The track further comprises reference elements, e.g. headers, interrupting the periodic variation. The phase of the periodic variation after the reference elements is indicative of a property of the record carrier for controlling the scanning of the record carrier in dependence of said property. In particular the phase may indicate whether or not the bottom of the pre-groove is closer to the scanning beam entry side of the disc. Further a scanning device is described comprising a detector for detecting said phase based on the varying signal. The device adapts its scanning control means to the indicated property. | ||||||

| A recording cover that provides a clean air distribution and micro cleanroom environment for recording of optical disc masters, while concomitantly serving the purpose of protecting the sensitive optically active lamina during transportation and storage of the optical disc substrate. A rigid, opaque, and reusable recording cover concentrically and fixedly, yet removably, fits over the optically active lamina of a disc substrate and creates an enclosed contaminate free space therebetween. The recording cover has a plurality of inwardly located air entrance cavities and a plurality of circumferentially located air exit holes, whereby clean and dry air is introduced into the air entrance cavities.
