Abstract
In an error recovery procedure (ERP) in a disk drive, the time needed to execute each step of the ERP is stored in a table. A timer measures the elapsed time from the start of the execution of the ERP, and the elapsed time is checked while executing the ERP. There are two types of ERP steps: those steps with (1) short execution times or (2) relatively long execution times. The two types of ERP steps are stored in different tables. An ERP step is selected and executed depending on the remaining execution time for the ERP.
