Enabling Femto Slider Technology: Reducing the Pitch Static Attitude and Roll Static Attitude Variations in Head Gimbal Assemblies

摘要

The move to Femto size sliders (Ref.1) marks the continued trend toward the miniaturization of the slider carrying the magnetic read write head in a hard disk drive. Femto size slider, because of the smaller area required, allows the fabrication of more sliders per unit wafer area than is possible with Pico sliders. In addition, The use of Femto sliders makes more disk real estate available for recording data than is possible with its bigger counterparts. The reduction in cost and the increase in the storage per disk are essential to ensure a continued decrease in the price/GB of storage.
