Magnesium-beryllium disk drive armset

In a disk drive system, an actuator for movably positioning and supporting a transducer over a disk of the disk drive system, wherein the actuator includes:

• an armset comprising a magnesium alloy mixture containing beryllium, and having a bore which is pivotable about a spindle, the mixture comprising from about 1% to about 99% by weight beryllium with the balance a magnesium component, and being free of intermetallic MgBe.sub.13 compounds;
• a bearing assembly interposed between the armset and the spindle;
• a flexible suspension coupled at one end to the armset;
• a transducer coupled to an opposing end of the suspension;
• a voice coil coupled to a set of brackets of the armset, wherein the voice coil and brackets are placed opposite the suspension and transducer such that a counter weight is not required to balance the armset relative to the bore.
