You can test duplicated copies for accuracy by performing our “Compare” function. This function compares the duplications to the original master disc by comparing the duplicated disc bit by bit. This process ensures the duplication is a 100% exact duplication of the original, providing optimal playback ability. If there is a recording problem, the duplicator will notify you on the display there was a failure and keep the affected disc in the machine so you can identify which one(s) are defective without disrupting the rest of the duplicating process.
