20100226046 | DISK DRIVE DEVICE FOR ROTATING A DISK - In the brushless motor, a hub has a cylindrical separating wall in between a yoke and two magnetic recording disks. The yoke is affixed to the inner surface of the separating wall of the hub using both a press-fit and adhesion. A first convex portion and a second convex portion are formed on the inner surface of the separating wall, and the yoke is pressed against these convex portions in the case where the yoke is press-fit. The first convex portion and the second convex portion are formed in a ring shape around the rotational axis of the motor. The diameter of the first convex portion is less than the diameter of the second convex portion. | 09-09-2010 |
20110085270 | Suspension for Protecting a Component from Mechanical Shock - Approaches for protecting a component when a hard-disk drive (HDD) experiences a mechanical shock. An HDD includes a suspension comprising a load beam, a gimbal, and a flexure tongue. A component, such as a microactuator, is mounted on the suspension. The flexure tongue extends to at least the edge of the microactuator that is furthest from the gimbal. The flexure tongue prevents the microactuator from contacting the load beam when the HDD receives a mechanical shock. Alternately, the flexure tongue may comprise a tip portion that extends beyond the edge of the microactuator that is furthest from the gimbal, and the tip portion of the flexure tongue may deform to act as shock absorber when the HDD receives a mechanical shock. Alternately or additionally, a padding material may be used to prevent the microactuator or the flexure tongue from contacting the load beam when the HDD receives a mechanical shock. | 04-14-2011 |
20120206836 | Pivot Attach Method for Disk Drive Actuator Using Taper Lock Shims - Various methods and apparatus relating to disk drive actuators and methods of manufacturing them are disclosed and claimed. In certain embodiments, a disk drive actuator assembly comprises a pivot bearing defining a pivot bearing rotational axis; an actuator arm including a bore, the pivot bearing disposed at least partially within the bore; a first tapered shim, interposed in the bore between the pivot bearing and the actuator arm, the first tapered shim having a thickness at a first end greater than a thickness at a second end; and a second tapered shim, interposed in the bore between the pivot bearing and the actuator arm, the second tapered shim having a thickness at a third end greater than a thickness at a fourth end; wherein the second tapered shim frictionally engages the first tapered shim to hold the pivot bearing substantially in place relative to the actuator arm. | 08-16-2012 |
20130120878 | INTEGRATED RECORDING HEAD WITH SELECTIVE MOVEMENT - A recording head for use in magnetic storage devices is disclosed. The recording head includes a transducer that is bi-directionally movable with respect to a surface of the magnetic storage medium, thereby enabling improved positioning of the transducer during recording head read and write operations. Various structures are disclosed to bi-directionally actuate the recording head transducer. In one embodiment, an interleaver assembly having a plurality of flexure assemblies employs a motor including magnetic portions for selective, bi-directional actuation. In another embodiment, electrostatic charges are employed in the flexure assemblies for selective actuation. In yet another embodiment, piezoelectric elements are included to provide for selective actuation. | 05-16-2013 |
20130128387 | SUSPENSION WITH HIGH CONDUCTIVITY GROUND LAYER - A suspension is configured to support a magnetic head slider having a recording head element for recording data signals to a magnetic recording medium and a microwave generating element that applies a high-frequency magnetic field to the magnetic recording medium when recording is conducted by the recording head element. The suspension includes a flexure that supports the magnetic head slider and a microwave signal transmission line. The microwave signal transmission line is connected to the microwave generating element and configured to transmit microwave signals for generating the high-frequency magnetic field. A portion that supports the microwave signal transmission line of the flexure includes a lamination structure, a ground layer with the thickness of 0.1 μm or greater and less than 2 μm and having higher conductivity than that of the flexure main plate, and an insulating layer that supports the microwave signal transmission line. | 05-23-2013 |
20130128388 | SUSPENSION WITH HIGH CONDUCTIVITY GROUND LAYER - A suspension is configured to support a magnetic head slider having a recording head element for recording to a magnetic recording medium and a microwave generating element that applies a high-frequency magnetic field to the magnetic recording medium when recording is conducted by the recording head element. The suspension has a flexure that supports the magnetic head slider, a microwave signal transmission line and a recording signal transmission line. The microwave signal transmission line is connected to the microwave generating element and configured to transmit microwave signals for generating the high-frequency magnetic field. The microwave signal transmission line and the recording signal transmission line are supported between the main body part and the support part, a portion of which has a first lamination structure where a first ground layer is conductive and a first insulating layer supports the microwave signal transmission. | 05-23-2013 |
20140247521 | GIMBAL ASSEMBLY RESONANCE MODE ANTI-BIASING - A data storage system includes an actuator assembly including a load beam having a base plate end and a slider end. A bias feature is formed in the load beam near the base plate end of the load beam. The bias feature is configured to induce lateral motion on the load beam when the slider end is displaced along a z-axis. An anti-bias feature is positioned between the bias feature and the slider end of the load beam. The anti-bias feature is configured to induce lateral motion on the load beam during resonance of the load beam to oppose the lateral motion induced by the bias feature. | 09-04-2014 |
