A method and apparatus is capable of recording optical information at high speed without using a high power laser beam. An intensity of a laser beam required in forming a land during recording optical information on an optical information recording medium is set to have a larger value for a greater linear velocity between a light source and the optical information recording medium such as an optical disc. As a result, a potion of the optical information recording medium in which a pit is to be formed can be sufficiently preheated even at the greater linear velocity, so that the pit can be formed without increasing an intensity of the laser beam required in forming pits.
