Abstract:
1. An optical disc recording device comprising: a laser element; a storage portion that stores maximum length information in which a maximum data length of data that the laser element can continuously record is set and optical output information in which an optical output characteristic of the laser element is set; a data split portion that splits data to be recorded in an optical disc into split data having a data length of the maximum data length or smaller; and an electric drive power setting portion that resets an base electric power value for controlling the laser element to emit a laser beam with a bottom power every time split data is recorded, wherein every time split data is recorded, the electric drive power setting portion sets a peak electric power value for controlling the laser beam to be outputted at a peak power based on the optical output information, the peak electric power value is set such that a ratio of a difference between the peak electric power value and the base electric power value to a difference between an erase electric power value for controlling the laser beam to be outputted at an erase power during a recording operation and the base electric power value is a predetermined ratio, the peak electric power value is larger than the erase electric power value, and the erase electric power value is larger than the base electric power value, and the electric drive power setting portion sets the peak electric power value for controlling the laser beam to be outputted only at the peak power throughout a period in which recording pulses are outputted.
