Abstract :
A high-speed process for servowriting hard-disk assemblies (HDAs) without an external clock head has been developed. This robust process achieves servo-pattern alignment accuracy comparable to or better than that achieved with conventional clock-head based servowriters at a substantially reduced capital and process cost
