    摘要: A system includes a first filter generating a first output signal based on an input signal. The first filter includes N tap weight coefficients, where N is an integer greater than 1. A first device updates the N tap weight coefficients of the first filter. A second filter generates a second output signal in response to the first output signal. The second filter includes M tap weight coefficients, where M is an integer greater than 1 and less than N. A second device determines a value of a first one of the M tap weight coefficients for each of multiple sampling times of the input signal. The second device updates the first one of the M tap weight coefficients based on the values of the first one of the M tap weight coefficients, a first gain constant, and a change in timing phase error of the first filter.

    摘要: A storage system includes a first buffer configured to store a first repeatable runout profile (RRP) for a sector of a rotating storage medium. A second buffer is configured to store a second RRP for the sector. A controller: controls a servo of the rotating storage medium based on the first RRP during a first revolution of the rotating storage medium; and learns the second RRP (i) while operating in a track-following mode, and (ii) during the first revolution. The controller ceases learning of the second RRP when one of (i) the controller is operating in a seek mode and (ii) the rotating storage medium is in an off-track state. Subsequent to the first revolution of the rotating storage medium and based on whether the learning of the second RRP was stopped during the first revolution, the controller replaces the first RRP with the second RRP in the first buffer.

    摘要: A method and apparatus is described for reducing RRO in storage systems. A disc may be partitioned into a number of equally spaced sectors. An RRO profile may be individually obtained for each sector, a runout control algorithm may be applied to each sector to generate an RROC waveform for the sector to suppress the RRO, and sector RROC waveforms may be assembled into an RROC waveform for a whole revolution and saved in a memory buffer for feed-forward control. The RROC is performed in the time domain, and it may be adapted for each sector to reject the RRO disturbance.

    摘要: A self-servo writing circuit including a controller. The controller is in communication with a read/write head having a read element and a write element, in which the read element is radially offset from the write element by a first predetermined distance. The controller is configured to i) cause the write element to write a first set of wedges of servo data onto a disk, and ii) after causing the write element to write the first set of wedges of servo data, cause the write element to write a second set of wedges of servo data onto the disk between the first set of wedges of servo data. The second set of wedges of servo data is radially offset from the first set of wedges of servo data based on the first predetermined distance between the read element and the write element.
