Abstract
An information recording apparatus having an energy beam generator for generating an energy beam, a power adjusting mechanism for setting a power level of the energy beam to a first power level state and a second power level state which is higher than the first power level state and a circuit for generating a basic recording pattern to record a recording medium. When a period of a recording timing generating clock in a recording mode is T, and a relative velocity of the energy beam and the recording medium is v, the circuit forming a sequence of the first and second power level states so as to effect recording.
