Information recording medium, recording method, recording apparatus and integrated circuit

A recorder for performing a write operation on a storage medium, which is adapted for multiple different writing speeds and on which writing conditions associated with each of the multiple writing speeds are stored in advance, with the best recording power,

• wherein the writing conditions include a parameter that defines a target for the recording power associated with each said writing speed, and
• wherein the recorder controls the recording power by calculating the target for the recording power associated with each said writing speed using the parameter such that signals generated by scanning recorded areas have substantially equal degrees of modulation.

A recorder for writing data on an information storage medium, on which a number of tracks are arranged either concentrically or spirally and on which data is to be written as marks and spaces between the marks by irradiating the storage plane of the tracks with a light beam,

• wherein in determining the power of the light beam to irradiate to perform the write operation,
• a first pulse position parameter value, a first recording power value for writing data at a first linear velocity using the first pulse position parameter value, and a second recording power value for writing data at a second linear velocity, which is lower than the first linear velocity, using the first pulse position parameter value are stored in a predetermined area on either the information storage medium or the recorder, and
• wherein the recorder calculates the first recording power for writing data at the first linear velocity based on the first recording power value, the second recording power value, and the second recording power in a situation where a test write operation has been performed at the second linear velocity using the first pulse position parameter value.
