Patent ID: 6958875

Claim:
A mechanism of self-vaccination providing optimized read channel parameters for a disk drive possessing a read channel optimization for a first temperature range, comprising: means for determining said disk drive operating at a second temperature outside said first temperature range to create a second read channel optimization process for said second temperature range; means for performing said read channel optimization process for said second temperature range to create a read channel optimization parameter list for said second temperature range; wherein said initial read channel optimization for said first temperature range is applicable to a sequence of at least two tracks on a disk surface within said disk drive; wherein said read channel optimization for said second temperature range is applicable to said track sequence on said disk surface; wherein said read channel optimization parameter list for said temperature range contains at least one member of a read channel parameter collection; wherein said mechanism, is further comprised of: means for said disk drive accessing any of said tracks belonging to said track sequence on said disk surface based upon said read channel optimization parameter list for said second temperature range whenever said disk drive is operating within said second temperature range; wherein the means for performing said range read channel optimization process is further comprised of: means for detecting when disk drive is idle and operating within said second temperature range; means for incrementally performing read channel optimization whenever disk drive is idle and operating within said second temperature range to create a temporary read channel optimization with a temporary quality measure; and means for updating said read channel optimization for said second temperature range with said temporary read channel optimization whenever said temporary quality measure is better than a current quality measure for said track sequence.
