摘要： A disk apparatus in which the position of a head is detected using servo information recorded on a recording plane of a disk. A first phase difference detecting section uses a zero-cross signal, a master clock, servo patterns corresponding to N cylinders (N is an integer equal to or greater than 2) so as to discriminate the different polarity information items contained in servo patterns from one another and to output phase difference information. A second phase difference detecting section uses the zero-cross signal, the master clock, half the servo patterns corresponding to the N cylinders so as to output phase difference information without discriminating the different polarity information items contained in the servo patterns from one another. When seek operation is performed, a selecting section outputs the phase difference information delivered from the first phase difference detecting section. When on-track control is performed, the selecting section outputs the phase difference information delivered from the second phase difference detecting section. A phase difference information integrating section integrates the phase difference information selected by the selecting section and outputs a position control signal for controlling the positioning of the head. The position signal can be demodulated accurately during/high speed seek operation of the head, without increasing complexity of the processing for the demodulation of the positional signal. The object is to make it possible to demodulate a position signal accurately during high speed seek operation of a head, without increasing complexity of the processing for the demodulation of the positional signal, thereby increasing the reliability of the disk apparatus.

摘要： A head position detecting method and apparatus for detecting a phase difference from servo data on a recording medium to detect the position of a head. This head position detecting method and apparatus detect the phase differences between the read pulse of the servo data read by the head and reference clocks, and average the phase differences to detect the head position. A training area having a timing signal recorded therein is provided before the servo data on the recording medium. A phase-lock loop circuit for generating reference clocks is synchronized with the timing signal to accurately detect the phase differences. An integrator is used to average the phase differences. This design ensures accurate detection of the head position even under fast seek. Further, a phase difference signal around a target cylinder is obtained by selecting the phase of the reference clock in accordance with the position of the target cylinder.
