| Abstract: | In this paper,an actual measure method for PSHQ(the Parameters of Sector Header Quality) is proposed,and the structure of the detecting system is introduced,based on the definition of PSHQ described in ISO/IEC 15041:1996 standard and analyzing the format and signals of sector header.The method reduces the testing complexity largely.Moreover,the testing results from the system are identical to the actual form of header signals and fully conform to the testing environment and PSHQ described in ISO/IEC 15041:1996 standard.The system has fully realized the detection for 5X Density Magneto-Optic disk. |
