    • An information recording apparatus has: a recording device for recording information onto an information recording medium, whose recording speed can be changed to first and second linear velocities, by irradiating laser light with a variable recording power; a measuring device for measuring reproduction quality by reproducing the record information recorded at the first linear velocity, if the recording speed is changed from the first linear velocity to the second linear velocity; a first calculating device for calculating a link power which is the recording power which gives the reproduction quality measured by the measuring device in the second linear velocity, on the basis of correlation information for representing a correlation between the recording power in the second linear velocity and the reproduction quality of the record information; and an adjusting device for adjusting the recording power at a time in stages or in continuity.
    • 信息记录装置具有:通过用可变记录功率照射激光将信息记录到信息记录介质上的记录装置,其记录速度可以改变为第一和第二线速度; 如果记录速度从第一线速度改变为第二线速度,则通过再现以第一线速度记录的记录信息来测量再现质量的测量装置; 第一计算装置,用于基于用于表示第二线速度中的记录功率与第二线速度之间的相关性的相关信息,计算作为以第二线速度给出由测量装置测量的再现质量的记录功率的链接功率; 记录信息的再现质量; 以及用于分级或连续地调整记录功率的调整装置。
