Document Type and Number:
Japanese Patent JP2001515640
Kind Code:
A
Abstract:
An optical record carrier (10) comprises a recording layer for recording information in a pattern of optically detectable marks in substantially parallel tracks (11-15). Neighboring tracks are separated by edges (16-20). Control information is encoded in a modulation of the transverse position of the even-numbered edges (16, 18, 20). The modulation of neighboring even-numbered edges have a mutual fixed phase shift. The modulation of the odd-numbered edges (17, 19) is such as to enhance the amplitude of a push-pull signal when scanning the tracks (11, 12) neighboring such an odd-numbered edge (17).
