摘要

A recording power determining method for determining a recording power of a laser light beam emitted when recording information on a recording surface of an optical disk, includes the steps of emitting a laser light beam to a recording area on the recording surface of the optical disk in which data is recorded; obtaining a value relating to reflectivity of the recording area based on the laser light beam reflected from the recording area; obtaining a beta value based on the laser light beam reflected from the recording area; and determining the recording power of the laser light beam based on the value relating to reflectivity, and the beta value.
