Quality Assurance in Mastering

The purpose of mastering is to produce perfect stampers with good pit geometry so that replicated discs meet industry standards. To ensure high quality levels:

Errors which can occur during mastering include variations in track pitch and linear velocity and pit geometry which can produce high jitter in the moulded discs. In addition poor stamper finishing can result in discs with eccentricity and/or unbalance out of specification.
