Method and apparatus providing a self-vaccine for a disk drive

A method of self-vaccination providing optimized read channel parameters for a disk drive possessing a read channel optimization for a first temperature range, comprising the steps of:

• determining said disk drive operating at a second temperature outside said first temperature range to create a read channel optimization process for said second temperature range;
• 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 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 for said second temperature range contains a parameter list contains at least one member of a read channel parameter collection;
• wherein said method, is further comprised of the step of:
• said disk drive accessing any of said tracks belonging to said track sequence on said disk surface based upon said read channel optimization for said second temperature range whenever said disk drive is operating within said second temperature range;
• wherein the step performing said read channel optimization process is further comprised of the steps of:
• detecting when disk drive is idle and operating within said second temperature range;
• 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
• 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.
