摘要

The position error signal is equal to the difference between the reference waveform and the measured relative position waveform derived from the readback signal from the head interacting with the disk, which is a method for recording a pattern on a medium, A method of magnetic servo writing on a rotating disk in a disk drive comprising a servo controlled actuator positioned radially, the method comprising: recording a servo pattern on a continuous radial track of the disk using an actuator; There is provided a method of recording a pattern on a medium comprising deriving a reference waveform as a function of a transfer function and one or more measured position waveforms. The frequency dependent gain of the servo loop may be set to be sufficiently high to provide a significant reduction in mechanical disturbance although the closed loop response of the servo loop is less than one at every multiple of the disk rotational frequency. Recording a series of first patterns along a track, displacing the head to a displaced position by a known fraction of the track, determining a position for determining deviation information indicative of head deviation from the known portion, Reading information from a selected one of the first patterns and using the variance information encoded in the second pattern to propagate the second pattern at the displaced position. The interval between adjacent tracks can be adjusted without recording the entire disc. The deviation of the demodulated position signal resulting from the irregular positioning error of the servo pattern can be eliminated. An apparatus for carrying out the above method and a disk drive recorded by the above method are provided.
