secures the slider to the load beam. The "pitch static attitude"
is defined by the free angle formed between the slider and the
horizontal when the suspension is held so that the slider is
positioned at the normal flying height.
The head suspension maintains the slider at a pitch static
attitude of approximately less than zero degrees. More
specifically, the head suspension maintains the pitch static
attitude at between approximately zero degrees and negative two
degrees. When the pitch static angle is negative, a moment acts
on the head suspension when the slider rests on the storage disk.
The moment inhibits the slider from rotating and tipping in the
event the motor cogs or the disk is shocked. By maintaining the
pitch static attitude at an angle between negative two and zero
degrees, the likelihood of contact between the non-padded portion
of the slider and the disk during the start up and shut down
phases is minimized. This minimizes the likelihood of drive
stiction failure and extends the life of the disk drive.
