Abstract

記録装置（１）は、第１基準ストラテジを調整することで、第１速度（Ｍｘ）でのジッタが所望の条件を満たすような第１最適ストラテジを算出する第１ストラテジ算出手段（２１、２２）と、第１速度と第２速度（Ｎｘ）との差異に応じたクロック周期変換処理を第１基準ストラテジに施すことで、第２速度で用いられる第２基準ストラテジを算出する第２ストラテジ算出手段（２２）と、第２速度で用いられる第２最適パワーを算出する第２パワー算出手段（２２）と、第２基準ストラテジを調整することで、第２速度でのジッタが所望の条件を満たすような第２最適ストラテジを算出する第３ストラテジ算出手段（２１、２２）と、第１基準ストラテジと第１最適ストラテジとの差異及び第２基準ストラテジと第２最適ストラテジとの差異の夫々に基づいて、第３速度（Ｃｘ）で用いられる第３最適ストラテジを算出する第４ストラテジ算出手段とを備える。
