Abstract:
High density magnetic disks are each placed on testers. Each tester tests a portion of the disk. If the tester finds an error, a new disk is placed on the tester. The tester goes to the allocated portion of the disk and tests whether the error is on the new disk. This process may be repeated several times to confirm the error. After an error is confirmed an alarm is sent indicating that there may be a defect in the disk manufacturing process.
