摘要： A method and an apparatus select the operational spindle rotation rate for a disk drive based on measured performance of the head-disk assembly. The position error values are measured and analyzed to generate a position error metric. Based on the value of the position error metric, an operational spindle rotation rate is selected for use when the head-disk assembly is combined with a controller to produce a disk drive.

摘要： A method and an apparatus for reducing position error signal in a disk drive, which has an actuator and a magnetic medium, write the servo tracks with a servo track writer using a varying increment. The servo tracks are written after the servo track writer incrementally moves the actuator by a non-constant amount. The non-constant incrementing enables a servo track writing operation to write servo tracks that are at least as wide near the outer circumference as they are near the zero skew position or near the inner circumference.

摘要： A method for reducing written-in runout of a disk drive writes a plurality of servo tracks onto a magnetic-storage portion of a disk that comprises a first radial band proximate the outer circumference of the disk, and a second radial band between the first radial band and the inner circumference of the disk. A first plurality of servo tracks is written to the storage medium in the first radial band at a first servo-writing spin rate. A second plurality of servo tracks is written to the storage medium in the second radial band at a second servo-writing spin rate that is different from the first servo-writing spin rate.

摘要： A method of manufacturing disk drives that are subject to disk pack imbalance includes steps of measuring the disk pack imbalance of each drive and assigning each of the drives to one of a predetermined plurality of categories, depending upon the measured disk pack imbalance. The measured imbalance of the disk drives assigned to fewer than the predetermined plurality of categories may then be reduced. Each category may be associated with one or more customers and the drives assigned to each category may be shipped to the associated customer(s).

摘要： An asynchronous system for testing disk drives includes a test platform that includes a plurality of slots for receiving and for providing communication with drives. The slots are segregated into a plurality of groups configured to satisfy predetermined environmental, communication bandwidth and test schedule requirements of the drives to be loaded therein. An automated loader/unloader is configured to selectively load drives into and out of the platform and to move drives between the plurality of groups. A module controller is assigned to each group of slots, each module controller being coupled to the slots of its assigned group and configured to administer at least one test to drives loaded in its assigned group while insuring that the predetermined environmental, communication bandwidth and test schedule requirements of its assigned group remain satisfied. A test matrix controller controls the loader/unloader to asynchronously move each drive that passes the test(s) administered in one group to a selected empty slot of another group for administration of a next test, to asynchronously move each drive that completes or fails the series of tests out of the platform. The moving steps are carried out without compromising the respective environmental, communication bandwidth and test schedule requirements of the plurality of groups.

摘要： A system and method for manufacturing disk drives, the disk drives having reliability attributes and manufacturing attributes, the manufacturing attributes comprising process or component manufacturing attributes is disclosed. The reliability attributes comprise measurements for predicting future reliability of the disk drives at the time of manufacture. The disk drives are prepared with a servo format. Each disk drive is connected to a test apparatus and then tuned to verify that each disk drive performs within expected limits. One or more technical screen tests are performed on all of the disk drives. A first sample set of the disk drives is selected automatically at a defined size using a randomizer. One or more extended tests are executed on the first sample set of disk drives to measure a margin magnitude for one or more of the reliability attributes. The margin magnitude is compared with a reference to detect a significant change. If a significant change in the margin magnitude from the reference is detected, then the defined sample size is adjusted. A second sample set of the disk drives is selected according to the adjusted sample size using the randomizer. The extended tests are then repeated on the second sample set to validate the significant change.
