I bore down hard on the fact my shop boss was servo trained and held my breath for fear I'd be asked how many men I had.

The split morph can be used as precision positioner, especially as the secondary actuator in dual stage head positioning servo system of high density hard disk drives.

Based on the idea of partial servo track writing (PSTW), a new servo track writing implementation method, named spiral servo track writing, for micro hard disk drives was introduced.
