摘要：Apparatus and Methods are disclosed for adaptively optimizing an ER filter in areadback system of a storage device, such as a disk drive. A sample value is read from thestorage device and an error measure is calculated between the sample value and an idealvalue. Pole parameters and zeros of the ER filter are modified to minimize the ER filter.The apparatus and methods disclosed can function with customer data to adaptivelyoptimize the ER filter in real time during normal operation of the storage device.Furthermore, temperature compensation circuits are disclosed to compensate fortemperature dependencies in the ER filter.
