INFORMATION CARRIER IN FORM OF OPTICAL DISK AND DEVICE FOR REPRODUCTION ON OPTICAL DISK

摘要

FIELD: engineering of information carriers. ^ SUBSTANCE: onto information carrier in form of optical disk, recording of information about address is performed along record track groove, provided with bends. Groove of record track consists of multiple single portions. Side surfaces of each one of these single portions have periodic shift in radial direction of disk. This shift has uniform oscillation period in direction of tracking. But, shift template is different and depends on each bit of information about address (sectioned information data), positioned in each one of single portions. ^ EFFECT: decreased unproductive losses, generation of sufficiently precise clock signal in accordance to bend of record track groove. ^ 4 cl, 61 dwg
