ABSTRACT:
An alternative method for testing the reading reliability of a CD-ROM player is provided. The method is applicable to both the semi-complete CD-ROM player without final packing on the production line as well as the complete CD-ROM player. The method includes first step of writing a predetermined data onto a plurality of sectors of a sample CD-ROM. The sector has a sector address and the predetermined data is a one-to-one function of the sector address and is stored in the sample CD-ROM in a format which does not include an error detection code and an error correction code. The sample CD-ROM does not has an error of un-correctable type. The method includes step of generating the predetermined data by the host computer based on the function and comparing the predetermined data with the set of data output by a de-scrambler operation of the invention to evaluate the reading reliability of the CD-ROM player.
