Defining from a first recording speed a second recording speed for recording on an information recording medium

An information recording method comprising:

• a recording process of irradiating an information recording medium with laser light and of recording information onto the information recording medium;
• an obtaining process of obtaining at least one of (i) a special OPC strategy for defining a waveform of the laser light used to calculate, at a first recording speed, an optimum laser power of the laser light for recording the information at a second recording speed different from the first recording speed, and (ii) a recording strategy for defining a waveform of the laser light used to record the information at the second recording speed;
• a power calculating process of calculating the optimum laser power by using the special OPC strategy at the first recording speed;
• and
• a controlling process of controlling said recording device to record the information at the second recording speed, by using the calculated optimum laser power and the recording strategy.

A computer readable recording medium with a computer program recorded thereon for tangibly embodying a program of instructions executable by a computer provided for an information recording apparatus, to make the computer function as at least one portion of a recording device, an obtaining device, a power calculating device and a controlling device,

• said information recording apparatus comprising:
• said recording device for irradiating an information recording medium with laser light and for recording information onto the information recording medium;
• said obtaining device for obtaining at least one of (i) a special OPC strategy for defining a waveform of the laser light used to calculate, at a first recording speed, an optimum laser power of the laser light for recording the information at a second recording speed different from the first recording speed, and (ii) a recording strategy for defining a waveform of the laser light used to record the information at the second recording speed;
• said power calculating device for calculating the optimum laser power by using the special OPC strategy at the first recording speed;
• and
• said controlling device for controlling said recording device to record the information at the second recording speed, by using the calculated optimum laser power and the recording strategy.
