摘要： The invention relates to a record carrier having a data zone (7) and an initial zone (25) and comprising a main channel storing content and a side channel storing address information and data relevant for making recordings. It further relates to methods and devices for protecting content stored on a record carrier and for reading out protected content. To provide a record carrier with content protection information (20, 22, 24, 26, 28) stored on it, which can be used with legacy devices without causing confusion, which can substantially be produced without extra production steps and which can be easily read by common devices, it is proposed to store said content protection information (20, 22, 26, 28) for protection of said content in said side channel in said data zone (7).

摘要： An optical record carrier (1) is provided with tracks having a groove (4) wobbled in a radial direction and predetermined positions (18) along the track. Embossed pits (18) at the predetermined positions represent addressing information. The phase of the wobble near the predetermined positions depends on whether a pit is present (18) on a predetermined position or not (19). The wobble changes phase between each two subsequent predetermined positions of which one on the positions contains no pit and the other position contains a pit.

摘要： An optical record carrier (1) is provided with tracks having a groove (4) wobbled in a transverse direction and predetermined positions (18) along the track. The wobble comprises a substantially monotonous undulation (15). Local excursions (16) of the groove superposed on the undulation at the predetermined positions represent position information, such as addresses. The spatial frequency of the undulation is lower than that of the excursions.

摘要： In an optical record carrier recording method for forming marks and lands by irradiating a radiation beam onto a recording surface of an optical record carrier, the radiation beam for each mark to be recorded is set to at least one write power level (Pw) capable of forming a mark during a mark period (31) and, for each land between the marks, to at least one bottom power level (P0) incapable of forming a mark during a land period (32). When recording a wobble signal on the record carrier, in order to achieve a better wobble signal-to-noise ratio during writing, the bottom power level (P0) is temporarily raised to an intermediate power level (Pi) during an intermediate period (34). Preferably, the intermediate power level (Pi) is set within a range of from 1.5 to 6, in particular, from 2 to 4, times the bottom power level (P0).
