    Abstract: An optical record carrier comprises substantially parallel tracks being divided into recording units having an address area (23, 24), adjacent address areas of adjacent tracks (43, 44) comprising shared address marks (48). Shared address marks (47, 48) are positioned in between adjacent tracks and arranged in sharing portions (40, 41) of the address area, each sharing portion sharing address marks only to one side. The address area also comprises a free portion (39) which is free from shared address marks, which free portion is aligned with a sharing portion (42) of an adjacent address area. This is advantageous for reducing crosstalk in the address read signal. The sequence of the free and sharing portions within an address area differs so as to be matching in adjacent address areas. Further an apparatus for scanning the record carrier is described, which apparatus comprises an optical system (52) for generating a spot (66) on the record carrier via a radiation beam (65), tracking means (51), address recovery means (50, 56) and positioning means (54) for moving the spot to a desired track. The address recovery means (50, 56) are arranged for detecting the free portion and deriving the sequence of the free and sharing portions.

    Abstract: An optical record carrier (RC and RC'), and methods and apparatuses for recording and reproducing an information on and from said optical recording carrier (RC and RC'), whereby the effects of crosstalk from adjacent tracks (TR) is reduced, and stable tracing control is possible, is achieved. A recording track (TR) to which information (Sm) divided into sector units (S) is recorded is formed in a spiral or concentric pattern on the surface of the optical record carrier (RC and RC'). Each sector further comprises sixty frames (FRf). Each frame (FR) comprises a re-sync pattern (RS), frame address (FA), data (INF), and postamble (PA) fields. Identification information (SA) indentifying the sector location of the information (INF) is recorded to the data block of the first frame (FR1). The user data (UDf) is recorded after the data (INF) is scrambled using a value (SR) generated by a fifteen-stage maximum-length sequence generator (603) based on the value of this identification information (SA). The correlation between signals on adjacent tracks (TR) is thus reduced, and the effects of crosstalk are randomized, thus reducing the effect on the track error signal and enabling extremely stable tracking control.

    Abstract: In the portions of a program region and a recording region which are in a boundary between these two regions, buffering regions in which effective data do not exist are provided. These buffering regions are determined as access inhibited regions, to/from which neither recording nor reproduction is carried out. Accordingly, the oscillation of a tracking servo which is liable to occur when an optical spot passes the boundary between the program region and recording region is minimized. This enables a constantly stable operation of the tracking servo to be attained, and the temporary omission of information signals to be prevented.

    Abstract: A recordable optical disc capable of optically recording the data. The disc has, as a pre-pit, a pit (4a) of a rugged pattern that corresponds to a synchronized signal portion recorded on the reproduction-only optical disc in the form of pits of rugged pattern. The region sandwiched by the pre-pits (4a) serves as a region for recording data (6a) supplementarily. Therefore, the recordable optical disc can be reproduced using a player for reproduction-only optical disc, enabling the two discs to be interchangeable.
