摘要： A disk drive and method are provided for controlling seeking of a transducer that is adjacent to a rotatable data storage disk in a disk drive. The disk drive includes an actuator for positioning the transducer relative to the disk, the method comprising. The actuator is controlled to move the transducer toward a target track on the disk during an initial phase of a seek mode during which the transducer is primarily accelerated toward the target track. During a settle phase of the seek mode which follows the initial phase the actuator is controlled to settle the transducer onto the target track. An initial position, an initial velocity, and an initial acceleration of the transducer are determined at a phase switch time at about when control of the actuator switches from the initial phase to the settle phase of the seek mode. Feed-forward control information is generated based on the determined initial position, initial velocity, and initial acceleration of the transducer. The actuator is controlled responsive to the feed-forward control information to settle the transducer onto the target track during the settle phase of the seek mode.

摘要： A disk drive includes a transducer and a rotatable disk, which includes a plurality of tracks. A vibration state of the transducer relative to the disk is determined. The transducer is positioned relative one of the tracks based on a compensation scheme that varies based on the determination of the vibration state. The compensation scheme may be varied by selecting among output of two or more compensators, based on the determined of the vibration state of the transducer, to control positioning of the transducer. The compensation scheme may alternatively, or additionally, be varied by varying a contribution from a vibration state actuator compensator to the control of positioning of the transducer. The vibration state actuator compensator is configured to improve transducer track following while the transducer is subjected to vibration.

摘要： An actuator control system and method for a hard disk drive comprising first and second actuators that support a head relative to a disk is disclosed. The actuator control system comprises a first stage, a second stage, a memory device, and a maximum stroke calculator. The first stage displaces the first actuator relative to the disk. The second stage displaces the second actuator relative to the first actuator. The memory device stores at least one data value indicative of a predicted response of the second stage. The maximum stroke calculator generates a predicted maximum stroke based on the at least one data value stored by the memory device. The second stage is deactivated when the disk drive initiates a seek operation. The second stage is reactivated based on a comparison of the predicted maximum stroke with a position of the second actuator.

摘要： The present invention is directed to utilizing the capabilities of multi-stage actuators in disk drives to write servo tracks that have a variable number of tracks-per-inch (TPI) from head to head, thereby improving both the performance of the drive and manufacturing yields. An appropriate TPI for a particular head has been found to depend on a number of factors that vary from head to head. Consequently, the initial step is to determine an appropriate TPI for at least one of the heads or, more preferably, all of the heads in the drive. The determination typically involves measurements such as read and write width measurements and off-track performance tests for the relevant heads. Once an appropriate TPI format has been determined, the servo tracks are written according to the TPI formats using either a servo track writer or self servo track writing.

摘要： A slider support structure is disclosed for minimizing off-rack due to disk flutter. In one embodiment, the slider support structure includes a gimbal assembly (306). The assembly (306) includes an outer ring (500) and an inner ring (502). The outer ring (500) is connected to the inner ring (502) via narrow strips (504 and 506) adjacent to the front (508) and back (510) surfaces of the slider body (512). The inner ring (502) is attached to the left (514) and right (516) surfaces of the slider body (512) via narrow strips (518 and 520). The strips (504 and 506) interconnecting the inner ring (502) and outer ring (500) define a flexible hinge that allows the slider body (512) to pivot relative to the assembly (306) about an axis (522) which, in this case, is the roll axis. Similarly, the strips (518 and 520) define a flexible hinge which allows the slider to pivot relative to the assembly (306) about another axis (524) which, in this case, is the pitch axis. The axes (522 and 524) are disposed close to the lower surface of the slider so that head off-track associated with such pivotal is minimized.
