Patent ID: 7251205

Claim:
A method of performing optimum test writing parameters for test writing of a writable optical storage media by using optimum test writing parameters which are specific to both an optical storage media recording/reproducing apparatus and to a writable optical storage medium manufactured by a respective one of a plurality of media manufacturers and which optimum test writing parameters are established independently of and without being constrained by default test-writing reference power parameters pre-recorded in the writable optical storage media during its manufacture, the method comprising: detecting information pre-recorded in a writable optical storage medium during its manufacture which uniquely specifies the writable optical storage medium's respective manufacturer; and performing a test writing parameter optimization on the writable optical storage medium to determine optimized test writing parameters for the writable optical storage medium, by writing test digital data to the writable optical storage medium while changing a light energy content in accordance with the optimum test writing parameters so that an optimum test writing light energy content representing optimum test writing parameters can have a reproducing characteristic specific to both the writable optical storage medium and the optical storage media recording/reproducing apparatus.
