In an embodiment, a solar energy system includes multiple photovoltaic modules, each oriented substantially at a same angle relative to horizontal. The angle is independent of a latitude of an installation site of the solar energy system and is greater than or equal to 15 degrees. The solar energy system defines a continuous area within a perimeter of the solar energy system. The solar energy system is configured to capture at the photovoltaic modules substantially all light incoming towards the continuous area over an entire season.

The present invention provides an interface for improving resonance control. The interface includes a first member having a first coupling portion, a mounting surface having a second coupling portion for coupling to the first coupling portion of the first member, and a raised engagement member located on at least one of the first member or the mounting surface. The raised engagement surface provides contact between the first member and the mounting surface.

A method of manufacturing a disc drive actuator is provided. The method includes manufacturing a disc drive actuator and machining a peripheral surface of the actuator. The peripheral surface is machined to obtain a desired profile dimension and thereby reduce variations in resonance characteristics from one actuator to the next.

Machining actuator periphery to reduce resonance variation

A flow-induced disturbance upon an actuator arm is reduced. A gas flow generated by a rotation of a disc is received and passed along a surface. The surface is mechanically isolated from the actuator arm. The surface redirects the received flow to include a substantial inward radial component so as to be better aligned along a leading edge of the actuator arm.

An interconnect apparatus for connecting a transducer to a flexible connector in an actuator assembly of a data storage device. The actuator assembly has a moveable actuator body and an arm extending from the body. The body defines a longitudinal opening aligned with the arm and associated with the placement of the interconnect apparatus. The interconnect apparatus includes a proximal end fixed to the actuator body and electrically connected to the flexible connector; a distal end fixed to the arm and electrically connected to the transducer; a medial portion electrically connecting the ends, a segment of the medial portion disposed within the actuator body opening; and a retaining member interposed between the medial portion and the actuator body within the opening, fixing the medial portion to the actuator body without using a bonding material.

A head interconnect circuit for connecting transducer elements of a data head to drive circuitry including an alignment finger on a lead tip for aligning leads relative to connectors or solder pads for electrically connecting heads to drive circuitry. A method for connecting a head interconnect circuit to a printed circuit supported on an head actuator including aligning an alignment finger on the lead tip with a printed surface of a drive circuit for soldering leads on the lead tip to solder pads or connectors on the drive circuit.

A head actuator supporting a data head for read or write operations. The actuator includes a head support excitation shield along a flow path to a leading edge of the slider (or head) to isolate the head support from flow induced excitation and vibration. A method for reading or writing data on a disc via a data head supported by a head support including rotating the disc to create an airflow stream and diverting the air flow stream to shield the head support from excitation.

An information handling system, such as a disc drive, includes a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The disc stack assembly includes a spindle hub rotatably coupled to the disc drive. The spindle hub includes a cylindrical portion as well as a flange on one end of the spindle hub. At least one disc and a disc spacer are clamped to the spindle hub. The disc spacer includes at least one disc contact surface. In some instances the disc spacer may have two disc contact surfaces. In the disc contact surface also has channel or groove therein. The channel or groove is annular and continuous so that no localized stress or a minimum amount of localized stress will be produced. The channel or groove is dimensioned so that a specific coefficient of friction is produced between the disc spacer ring and the surface of the disc. The disc contact surface may have more than one channel or groove therein. Assembling the disc stack includes placing the at least one disc moveably about the spindle hub and placing the disc spacer ring moveably about the spindle hub. The disc contact surface of the disc spacer ring which has the groove or channel therein is positioned so that it contacts the surface of the disc. The disc and disc spacer are then clamped to the spindle hub with a force sufficient to cause the surface of the disc to protrude into the groove of the disc spacer ring.
