  • Publication number: 20120026620
    Abstract: Methods and apparatus are provided for gain estimation using servo data with improved bias correction. The gain is estimated using a preamble in a servo sector by obtaining a first gain estimate using a first gain estimation algorithm (such as a Zero Gain Start Algorithm) and a first portion of the preamble; storing the first portion of the preamble in a memory buffer; obtaining a second gain estimate using a second gain estimation algorithm (such as a Zero Forcing algorithm) and the first portion of the preamble; and processing Servo Address Mark (SAM) and Gray data in the servo sector using the first gain estimate substantially simultaneous to the step of obtaining the second gain estimate. A gain error can be obtained by calculating a difference between the first gain estimate and the second gain estimate. The gain error can be used in burst processing of the servo data.

  • Patent number: 8049982
    Abstract: Methods and apparatus are provided for measuring servo address mark distance in a read channel using selective fine phase estimates. A distance between servo address marks (SAMs) in servo data of a magnetic recording media can be computed by obtaining a count of a number of time intervals between SAM patterns; obtaining a plurality of fractional phase estimates; selecting at least one of the plurality of fractional phase estimates as a selected fractional phase estimate based on a selection criteria; and combining the count and the selected fractional phase estimate to compute the distance. The fractional phase estimates can include a first fractional phase estimate having a lower resolution and higher accuracy in the presence of frequency errors relative to a second fractional phase estimate and wherein the second fractional phase estimate has more resolution and lower accuracy in the presence of the frequency errors relative to the first fractional phase estimate.
