Abstract:
1. A method of recording marks onto an optical disc, the optical disc comprising an information layer, by irradiating the information layer by a pulsed radiation beam, a mark (I the method determining: the number m of write pulses in a mark having the shortest time length corresponds to Ceiling (n/a), wherein Ceiling (n/a) defines the smallest integer that is larger than n/a the number m of write pulses in the marks of other time lengths corresponds to Floor(n/a), where Floor(n/a) defines the largest integer smaller than n/a, wherein a is an integer number larger than or equal to 2, wherein an individual write pulse exceeding a known threshold is recorded as a sequence comprising two write pulses, said threshold being determined with respect to a median write pulse length in the sequence.
