摘要： The invention relates to control systems for data storage media. More particularly, the invention relates to a system, method and apparatus for forming various frequency modulation patterns on storage media for providing position error signals. The invention also relates to forming various frequency modulation patterns on storage media for providing position error signals having a continuously varying frequency that is proportional to the position of a read/write transducer head within a track defined on a storage medium. The invention also relates to providing a demodulated signal that is proportional to a continuously varying position error signal frequency and thus to the position of the read/write head within a track defined on a storage medium.
摘要翻译：本发明涉及用于数据存储介质的控制系统。更具体地说，本发明涉及用于在存储介质上形成各种频率调制模式以提供位置误差信号的系统，方法和装置。本发明还涉及在存储介质上形成各种频率调制模式，以提供具有连续变化的频率的位置误差信号，该连续变化的频率与在存储介质上限定的轨道内的读/写换能器头的位置成比例。本发明还涉及提供与连续变化的位置误差信号频率成比例的解调信号，从而提供读/写头在存储介质上限定的轨道内的位置。
