| By analyzing and researching the physical format, logic format, file system and ATAPI interface protocol of the CD/VCD/DVD disc, disc drive performance test program for Preview Group Ltd. product line based on DOS had been designed, the demands to test the disc drivers had been implemented fast,well and truly.Commercial test software such as NERO,CDWinBench was based on windows and couldnot satisfied the needs of product lines on simpleness and speediness. This program was used to test the basic performance of disc drivers in PIO &DMA mode based on ATAPI transport protocol and implemented easily. The whole system included two modules: the first module was disc driver interface program and its function was to control the driver to implement the works such as initial,tray in/out, play audio, write disc and test read rate& write rate and 1/3 seek time and full seek time. The second module was the firmware to control the test process. It provided the GUI and results'store & compare function and user can set the test driver,test items and intervals. Development tools are MASM and Borland C++ 3.0.The results showed that this system was suited to 98% disc drivers on market. It was friendly, stably and conveniently, so test process was fast and truly.
