Femto sliders are currently the smallest among standardized sliders and are 20% the size of Mini sliders. The current trend is to move from Pico sliders, 30% sliders, to Femto sliders.

HDD composed of Femto sliders are on the market these days, in which NHK's highly accurate suspensions are utilized.

---Dimension of Femto Slider---

Pico: 1.25 x 1.0 x 0.30 (Mass 1.6mg)
Femto: 0.85 x 0.7 x 0.23 (Mass 0.6mg)

 

Merits & Demerits for Using Femto Slider
Merits
1. Slider Cost Reduction
2. Reduction in Power Consumption
3. Etc…
Demerits
1. Fly Height Control Difficulties
2. Etc…

 

Fly Height Sensitivity is increased by;

O Flexure Pitch Stiffness
O Flexure Roll Stiffness
O Suspension Gramload

For using a FEMTO Slider

O Designing a low stiffness flexure with a high degree of accuracy for pitch and roll
O Improving Gramload accuracy
O Weight saving loadbeam to avoid deterioration of shock resistance due to a reduced load

We are pursuing continuous development and design of Femto Slider Suspensions that satisfy the conditions mentioned above.
