Abstract
An optical recording medium containing control information to set the write power at an optimum level for recording information on the medium. The control information includes a preset value of the derivative of the modulation of a read signal with respect to the write power. The optimum write power is derived from values of the modulation measured from test patterns on the medium and the preset value recorded on the medium.
