Abstract
An information recording method and an apparatus therefor, wherein a recording compensation controlling unit receives data to be recorded and determines whether a pulse timing adjustment is to be performed or not, and instructs an APC to adjust the timing thereby to advance the pulse start timing of laser light and/or to delay the pulse termination timing when the pulse timing adjustment is to be performed. The recording compensation controlling unit determines the pulse timing adjustment corresponding to the presence or absence of a predetermined “space, record mark”, whereby the positional shift quantity of leading and trailing edges is reduced even for the marks having a fine dimension, and the jitter is reduced.
