Customized data recovery procedures selected responsive to readback errors and transducer head and disk parameters

摘要

A method and apparatus are provided for data recovery in a disk drive data storage system of the type including at least one disk surface and at least one transducer head for reading and/or writing data to a respective disk surface. A plurality data recovery procedures (DRPs) are stored. When a readback error is detected in a readback data signal, a plurality of predetermined transducer head and disk parameters are identified. One of the stored plurality of data recovery procedures (DRPs) is selected responsive to the detected readback error and the identified plurality of predetermined transducer head and disk parameters.
