摘要： In a user data area, control of recording laser power cannot be performed accurately. In recording data in the user data area, data for the control of recording laser power is also recorded together with user data to be recorded. By reproducing the data for control of recording laser power, the recording laser power can be controlled to be suitable for a user data recording position and user data is recorded with use of the thus-controlled laser power. In this way the recording laser power can be controlled to be suitable for a recording position on an optical disc and hence an optical disc superior in recording quality is realized.
