MAM-A CD-R media benefits from a consistency and process control which no other manufacturer can equal. Since we don't rely on third-parties to provide our technology, production facilities, or raw materials, MAM-A CD-R customers know that each component and each step in the manufacturing process has been subjected to the most rigorous quality controls in the industry. Every MAM-A CD-R is warranted for life. No other CD-R media manufacturer offers a warranty of this strength. Every MAM-A CD-R is certified for use with all high speed recorders up to 52X. There are two reasons for this. Firstly, MAM-A's molding process results in discs that are flatter than the competition. While all discs are slightly warped, if they are warped beyond a certain tolerance they cannot be used for high speed recording. Secondly, the unique characteristics of the Phthalocyanine dye simply works better in high speed writers than other dyes. Some of the key parameters to judge CD quality actually improve at higher speeds with MAM CD-R.
