Abstract
A data transducer position control system for data disk storage drive system involves an electronically and mechanically improved method and apparatus for position control of the data transducer adapted to write and/or read information data in and/or from the data tracks provided on a data disk. Particularly, the system comprises a positioning device for actuating the data transducer, a position encoder for detecting the position of the data transducer, a tracking error detector for detecting the relative position of the data transducer to the selected data track, and compensating position calculator for precise tracking so that the speed-up of track access can be effected, that the accuracy in positioning can be improved, that the system itself can be compact in size and reduced in energy consumption, and that the control electronic system can also be simple in arrangement.
