Abstract
Window center settings in a read channel of a magnetic disk drive are controlled. The magnetic disk drive is suitable for reading data from a magnetic disk. A number of read operations are performed and data is read from the magnetic disk. Read errors are detected during the read operations. The number of read errors is recorded and error types are determined. Adjustment of the window center settings is controlled based on the number of read errors detected and the error types determined.
