ABSTRACT:
An optical disc has a plurality of tracks for recording information represented as marks and spaces between the marks. The marks are formed by an optical beam modulated by a plurality of drive pulses where a number of the drive pulses is determined according to a length of a mark part in the original signal to be recorded to the track. The optical disc has a data recording area for recording data, and a control information recording area for storing a first pulse position Tu value indicative of rising edge of the first drive pulse for determining a start position of a mark to be recorded, and a last pulse position Td value indicative of falling edge of the last drive pulse for determining an end position of a mark to be recorded.
