Abstract
The characteristic of embossed information is very important for magneto otpical disk, which is used by the magneto optical driver to control the axial focusing and radial tracking servos on the information tracks and to search the sectors. It must be tested in the process of development and production of magneto otpical disk. the characteristics of 4X-density magneto otpical disk's embossed information are described in this thesis; the test method of the header signal and groove signal is discussed based on the international standard test condition. A test system has ben designed which can measure the characteristics of embossed information of magneto optical disk, and a sample disk's test result is given in the end.
