摘要
PROBLEM TO BE SOLVED: To provide a system and a method for self-servowriting which are more flexible and to overcome the defects of known self-servowriting technology.;SOLUTION: The method and system for self-servowriting to a data storage medium are disclosed and include a step or means for servo control over the propagation bursts of a propagation pattern arranged on a track other than a last track. A reference level used for positioning a recording head is kept within a usable dynamic range needed, to hold servo track intervals constant over the medium. The method and system are described, in relation to a rotary actuator having read and write heads at an interval. A similar method for writing a trigger or timing bursts of the propagation pattern is also disclosed.;COPYRIGHT: (C)2002,JPO
