Abstract
A method for optimizing read/write channel parameters of a hard disk drive. The process includes measuring a first bit error rate of a head using an initial set of read/write channel parameters and varying all of the read/write channel parameters with a random jump. The random jump may be created from the generation of a random number. The process then includes measuring a second bit error rate of the head using the varied read channel parameters and accepting the varied read/write channel parameters as the new optimum, if the second bit error rate is lower than the first bit error rate.
