Self-servo writing using recording head micropositioner

摘要: Servo tracks are written onto different disk surfaces using multiple recording heads within a drive without requiring servo writing machine or clean room conditions. Microactuators in the reference capable of independent motion with respect to one another, which allows be surfaces. The process begins as biased against crash stop, and then moved an adjacent track. One writes track at this position when microactuator head is centered. This follows its centered, while other move radial direction write information on their respective tracks. Reference successively used away from stop.
