Abstract
A method and device for recording information in units on a partly recorded writable record carrier, e.g. an optical disc. The information is recorded in a track represented by series of marks of different runlengths between a minimum runlength and a maximum runlength and synchronizing patterns of marks, which patterns do not occur in the series of marks and comprise at least one long mark of at least the maximum runlength. At least one information unit is encoded into a modulated signal comprising signal elements corresponding to said marks. The track is scanned up to a link position before a selected one of said addressable locations, and the modulated signal is recorded from the link position. The modulated signal is provided at the begin and/or at the end with a link signal element corresponding to a mark of at most the minimum runlength.
