..., lubricants, which are difficult to transfer to the air-bearing surfaces, should be developed and used in hard disk drives. The effect of molecularly thin liquid lubricant films on slider hysteresis behavior in hard disk drives has been investigated experimentally. It has been attempted...

...Jia-Yang Juang; David B. Bogy; C. Singh Bhatia To achieve the areal density goal in hard disk drives of 1 Tbit ∕ in . 2 the minimum physical spacing or flying height (FH) between the read/write element and disk must be reduced to ∼ 2 nm . A brief review of several FH adjustment schemes is first...
