A method of test recording to determine a recording power used to record information to an optical disk by test recording which records predetermined data to a plurality of areas in a test recording area of the optical disk, said method comprising:
- moving a light spot on the optical disk in a direction from an outer periphery to an inner periphery of the optical disk to record the predetermined data to the test recording area;
- wherein usage of the test recording area moves from an inner part of the plurality of areas towards an outer part of the plurality of areas to carry out the test recording.
An apparatus for recording information to an optical disk comprising:
- a power determining section operable to determine a recording power used to record information to the optical disk by test recording which records predetermined data to a plurality of areas in a test recording area of the optical disk;
- wherein said power determining section moves a light spot on the optical disk in a direction from an outer periphery to an inner periphery of the optical disk to record the predetermined data to the test recording area, and usage of the test recording area moves from an inner part of the plurality of areas towards an outer part of the plurality of areas to carry out the test recording.
