ABSTRACT:
An actuator coil for a disk drive is formed of materials and processed in a manner such that the amount of outgassing that occurs in normal operation of the disk drive is minimized. An insulative coating, such as polyurethane which is rated well above the normal operating temperature is first applied to drawn copper wire. Then, a polyamide bond coating was used to cover the insulative coating. Next, a lubricant having a low average molecular weight was selected. The resulting wire was then wound to form the actuator coil. The coil is then cured at a high temperature for an extended length of time to drive off solvents and allow the polymers to crosslink and stabilize.
