摘要： A suspension is disclosed that includes a pre-load section and a load section. The pre-load section is configured to be connected to a base. The load section is connected to the pre-load section and comprises a load beam portion, a flex circuit portion, and a brace. The brace extends laterally exterior to the load beam portion proximate to the pre-load section. The brace increases the lateral sway vibration mode of the load section, allowing the load beam portion to be narrower, and provide a decreased weight and increased torsion vibration mode, while also maintaining an increased lateral sway vibration mode.

摘要： In one implementation, the presently disclosed technology teaches an apparatus with a head attached to an end of a baseplate. The baseplate includes a tilted section that causes a torsion axis of the baseplate to pass near the head. In another implementation, the presently disclosed technology teaches an apparatus with a load beam attached to a baseplate. The apparatus also includes a head attached to an opposite end of the load beam from the baseplate. The baseplate includes a mass-shifted section that causes a torsion axis of the apparatus to pass through the head. In yet another implementation, the presently disclosed technology teaches a method for reducing baseplate resonance amplitude. The method includes shifting a baseplate mass on a suspension toward an adjacent disc surface to move a baseplate torsion axis to pass near a head.

摘要： A head suspension for mounting a head assembly in a disc drive that utilizes dynamic loading and unloading of the head assemblies. The head suspension includes a ramp contact feature that is located at the distal end of the head suspension and is substantially laterally centered on the head assembly, in order to minimize induced attitude moments at the time of loading and unloading of the head assemblies. The head suspension also provides selectable vertical separation between the ramp contact feature and the associated disc surface, in order to allow design flexibility. The head suspension also includes displacement limiting features which prevent plastic deformation of the gimbal during head lifting, and which contribute to positive pitch attitude during head unloading, to minimize the amount of disc surface which must be reserved for head unloading.

摘要： A head suspension assembly, particularly useful in a disc drive that incorporates a head/microactuator assembly and dynamic loading and unloading of the head/microactuator assembly into and out of operative engagement with a disc. The head suspension includes a gimbal that that mounts the head/microactuator assembly via the microactuator, and thus allows the head assembly to be microstepped by the microactuator. The gimbal further includes reverse bending features providing increased pitch attitude compliance, and limiting features which interact with cooperative lifting features on the rigid beam of the head suspension to control the static attitude extremes of the head assembly during dynamic unloading of the head/microactuator assembly from operative engagement with a disc. In a further aspect of the invention, the head suspension includes mechanisms for controlling the attitude of the head/microactuator assembly relative to the disc during dynamic loading of the head/microactuator into operative engagement with the disc.

摘要： A head suspension mounts a head assembly in a disc drive. The head suspension includes controllable bending elements on the gimbal portion of the head suspension which allow dynamic control of the flying attitude of the head assemblies, and thus the flying height. In a first embodiment, the control elements are bi-metal features that utilize differential thermal expansion to control the flying attitude. In a second, and presently preferred, embodiment, the control elements are piezo-electric elements which provide bi-directional control of associated elements of the gimbal portion of the head suspension. In another aspect, the controllable bending elements are used to increase the flying height of the head assembly as the head assembly is moved from the data recording area of the disc into engagement with a textured landing zone.

摘要： A system for unloading heads from and loading heads into cooperative engagement with discs in a disc drive, including a novel head suspension for mounting and supporting the heads. The head suspension includes a primary ramp contact feature formed as a portion of the load beam portion of the head suspension and a secondary ramp contact feature formed as an extension of the mounting tab of the gimbal portion of the head suspension. The primary ramp contact feature acts as the principal lifting mechanism of the head suspension, while the secondary ramp contact feature serves to controllably lift the head. In an alternative embodiment, only the secondary ramp contact feature is used for the unloading and loading of the head.
